I factory reset my MacBook and set up everything new to get rid of the multiple python version chaos I had on my old laptop.
Only thing I have installed atm is Anaconda. I created a new conda environment with python 3.9 and activated it in my zsh Terminal.
Still when I type "which python" it shows "/usr/bin/python" containing the MacBook standard Python2.7 version.
How can I make environments use their own dedicated version?
Edit for Code:
conda activate myenvname
which python
Trying to access the folder where the anaconda python should be leads to
cd: no such file or directory: /Users/marcus/anaconda/bin
When you install anaconda through the terminal it provides an option to prepend anaconda to the system path. make sure to choose yes. If you don't, you'll need to provide the full path to your anaconda installation when activating an environment, as in:
source <path to conda>/bin/activate
conda init
You'll need to do this in each shell session. Alternatively, you can use the anaconda terminal.
To fix this, Anaconda does not recommend fixing your path manually. I think this is because there are a number of things anaconda does when setting up your shell if you choose "yes". Instead, the recommended fix is to uninstall and re-install anaconda (and pick yes this time ;)).
See the Anaconda docs for more information.
I have installed anaconda and create and activated an environment with anaconda prompt.
But when I open python with anaconda, whether inside my anaconda folder or inside the environment folder in it, (or even if I open a python file with spider), it seems it is not using anaconda (according to sys.version).
Indeed python tells me "this python is in a conda environment, but the environment has not been activated".
I have already activated my environment in conda prompt, and I had no error message, so I guess it was succesfful. I have also tried to set my path with in conda prompt: set PATH=C:\Anaconda\envs\py33\Scripts;C:\Anaconda\envs\py33;%PATH% (with my right personal path).
Would you know what is happening?
Thank you
picture of my problem
Anaconda (listed as "Python 3.6.0 (Anaconda 4.3.1 64 bit)" ) is in my programs and features list, but there is seeming no Anaconda Navigator desktop app, as their seems to be no icon on my desktop and I am unable to search for it through "Start". Could this be because I have the 32-bit version of Anaconda downloaded and I have a 64-bit OS (I thought I should do this because Python on my computer was 64-bit) or because I downloaded Anaconda under "users" instead of Desktop. I also downloaded Anaconda twice, if that could be causing some of the problem. I have a Windows 10 laptop, if that is any help.
Try to
source ~/anaconda3/bin/activate root
anaconda-navigator
https://github.com/ContinuumIO/anaconda-issues/issues/1580
Open up a command terminal (CTRL+ALT+T)
and try running this command:
anaconda-navigator
When I installed Anaconda, and read the website docs, they said that they tend to not add a file or menu path to run the navigator because there are so many different versions of different systems, instead they give the above terminal command to start the navigator GUI and advise on setting up a shortcut to do this process manually - if that works for you it shouldn't be too much trouble to do it this way - I do it like this personally
How I solved this issue:
1. Be connected to the internet.
2. Open the Anaconda Prompt (looks like a regular command window).
If you installed the .exe in your /name/user/ location you should be fine, if not navigate to it.
Then start an environment.
conda info --envs
Then run
conda install -c anaconda anaconda-navigator
Press y when prompted (if prompted). It will being downloading the packages needed.
Then run your newly installed Anaconda Navigator
anaconda-navigator
It should start, and also appear in your regular windows 10 apps list.
activate the virtual env with command:
conda activate base
run anacond anavigator
anaconda-navigator
when you will type anaconda in windows 10 search bar it will give you the list as
then in terminal you have to type anaconda-navigator as
it will start anaconda on your machine.
Yet another option which worked in my case on Windows 10: Try uninstalling your previous installation, restart the system and run the installation again. Make sure you don't start any programs before installing Anaconda. You will find the installation finishes without prompting any kind of errors.
Type in Anaconda in your Windows 10 Search bar. You will find Anaconda Prompt appear.
I figured out the reason as to why:
1-There seems to be no navigator icon
2-When conducting the above steps of running the "anaconda-navigator" command in prompt (whether cmd or Anaconda) it yields "anaconda navigator is not recognized as an internal or external command"
This was very frustrating to me as I'd installed the proper version multiple times with no avail.
To solve this problem :
in the installation process, there will be an advanced options step with 2 selections one of which is unchecked (the top one). Make sure you check it which will add the navigator to the path of your machine variables.
Cheers,
Hossam
it works :
export PATH=/home/yourUserName/anaconda3/bin:$PATH
after that run anaconda-navigator command. remember anaconda can't in Sudo mode, so don't use sudo at all.
I faced the same problem on Windows 10. As soon as I cleared my Path variable from edit environment variables option, the icon started to appear. It was occurring because I had previously installed python 3.6.1 on my computer and added it to my path variable as C:\Python36;C:\Python36\DLL; and so on. There isn't any need to uninstall Anaconda Navigator and start from scratch if you have correctly followed the steps mentioned at the documentation for it.
Try restarting the system! You will be able to find the navigator once you restart the system after installation.
Tried all solutions here but these 2 steps solved the issue:
1) manual update of open-ssl from here:
https://slproweb.com/products/Win32OpenSSL.html
2) update OpenSSL using conda update openssl command in the Anaconda Prompt
solved the issue!
I had a similar issue today where only the prompt was available after installation.
Finally solved this by un-installing my regular python installation and then install anaconda(anaconda 3 v5.2.0, with python 3.6).
I also have the issue on windows when i am unable to find the anaconda-navigator in start menu.
First you have to check anaconda-navigator.exe file in your anaconda folder if this file is present it means you have installed it properly otherwise there is some problem and you have to reinstall it.
Before reinstalling this points to be noticed
1) You have to uninstall all previous python folder
2) Check you environment variable and clear all previous python path
After this install anaconda
your problem will be resolved if not tell me the full error i will try to solve it
Uninstall your Anaconda, delete the folder where it was. Then reinstall it.
You might not be in a anaconda environment
Below is a link how to activate the environment from the official documentation
On Windows, in your Anaconda Prompt, run activate myenv
https://conda.io/docs/user-guide/tasks/manage-environments.html#activating-an-environment
And then run the anaconda navigator from the anaconda prompt by entering the command anaconda-navigator
100% Solved.
While Installing make sure you are connected to Internet.
If already installed anaconda, open the anaconda command prompt and type following command:
conda install -c anaconda anaconda-navigator
(internet connection is required)
Note: In some cases restarting may solve the issue of navigator.
This is what I did
Reinstall anacoda with ticked first check box
Remember to Restart
I have that error an the solution was to install the Win64 OpenSSL.
https://slproweb.com/products/Win32OpenSSL.html
Download and install Miniconda first from this link and later on download and install Anaconda. Then you will be able to see the navigator in your all programs list in the start menu. I hope this will help you. Let me know in case of any concerns.
In my case; it was available in the anaconda folder in "All App" from main menu
For people from Brazil
There is a security software called Warsaw (used for home banking) that must be uninstalled! After you can install it back again.
After thousand times trying, installing, uninstalling, cleanning-up the regedit that finally solved the problem.
First Run This Command
conda config --set auto_activate_base True
Then Run This Command
anaconda-navigator.
Turn off your internet connection, then open your terminal and type anaconda-navigator or type anaconda prompt in the search bar and double click on the anaconda prompt.
If anaconda is opened, then you can turn on your Wi-Fi.
I'm also faced with this issue. When I checked conda --version got a command not recognized error. Then I set the environmental variables as in https://stackoverflow.com/a/61372328/13370201. After that run anaconda navigator command. Then it started to initializing anaconda navigator.This tutorial also help for me.
I faced the same problem in Solus Baidge but I solved by activating the conda environment.
First activate
conda activate
Then run the navigator
anaconda-navigator
Make sure to run the installer as admin
In my case (Windows 11) it was a permission problem. Make sure to run the installer as administrator. You can check this by modification of the path in the installer process.
Further steps to handle the problem:
Uninstall your actual anaconda version.
Delete old Data found in:
C:\Users\YourUsername\AppData\Roaming
C:\Users\YourUsername
(In my case it was called .anaconda and .conda folder)
Restart PC
Install Anaconda as admin
The followng command solved my issue.
pip install --upgrade pywin32==228
On windows 10, I faced the same error - only Anaconda Prompt was showing in the startup menu. What I did is i re-installed Anaconda and selected install for all users of the pc (in my initial installation I have installed only for current user).
What finally worked for me was:
Uninstalling Anaconda
Deleting all files that has "conda" in them - most of them should be
located in: C:\Users\Admin
Delete especially the "condarc" file.
Reboot
Installed 32-bit installer (even though my system is 64-bit) and reboot
Finally worked. I have not yet re-tried with 64-bit installer, since I have a time critical project, but will do when again I have spare time.
P.S. what broke Anaconda for me was a blue screen I got while updating Anaconda. I guess it did not clear all old files and this broke the new installs.
I too faced a similar issue when I was not able to find the Anaconda Navigator Desktop app in the start menu. But do not worry , Go to start Menu and Type Anaconda Navigator. Now within the apps menu you will find anaconda navigator with its icon. Click on that. After clicking you will find a command prompt dialog opened and a .exe file runs on your machine. Wait till it completes.
The Anaconda Navigator app opens on your machine.
I installed Anaconda 4.4.0 (Python 3.6 version) on Windows 10 by following the instructions here: https://www.continuum.io/downloads. However, when I open the Command prompt window and try to write
conda list
I get the
'conda' command is not recognized...
error.
I tried to run
set PATH=%PATH%;C:\Users\Alex\Anaconda3
but it didn't help. I also read that I might need to edit my .bashrc file, but I don't know how to access this file, and how I should edit it.
In Windows, you will have to set the path to the location where you installed Anaconda3 to.
For me, I installed anaconda3 into C:\Anaconda3. Therefore you need to add C:\Anaconda3 as well as C:\Anaconda3\Scripts\ to your path variable, e.g. set PATH=%PATH%;C:\Anaconda3;C:\Anaconda3\Scripts\.
You can do this via powershell (see above, https://msdn.microsoft.com/en-us/library/windows/desktop/bb776899(v=vs.85).aspx ), or hit the windows key → enter environment → choose from settings → edit environment variables for your account → select Path variable → Edit → New.
To test it, open a new dos shell, and you should be able to use conda commands now. E.g., try conda --version.
Things have been changed after conda 4.6.
Programs "Anaconda Prompt" and "Anaconda Powershell" expose the command conda for you automatically. Find them in your startup menu.
If you don't wanna use the prompts above and try to make conda available in a standard cmd.exe or a standard Powershell. Read the following content.
Expose conda in Every Shell
The purpose of the following content is to make command conda available both in cmd.exe and Powershell on Windows.
If you have already checked "Add Anaconda to my PATH environment variable" during Anaconda installation, skip step 1.
If Anaconda is installed for the current use only, add %USERPROFILE%\Anaconda3\condabin (I mean condabin, not Scripts) into the environment variable PATH (the user one). If Anaconda is installed for all users on your machine, add C:\ProgramData\Anaconda3\condabin into PATH.
How do I set system environment variables on Windows?
Open a new Powershell, run the following command once to initialize conda.
conda init
These steps make sure the conda command is exposed into your cmd.exe and Powershell.
Extended Reading: conda init from Conda 4.6
Caveat: Add the new \path\to\anaconda3\condabin but not \path\to\anaconda3\Scripts into your PATH. This is a big change introduced in conda 4.6.
Activation script initialization fron conda 4.6 release log
Conda 4.6 adds extensive initialization support so that more shells than ever before can use the new conda activate command. For more information, read the output from conda init –help We’re especially excited about this new way of working, because removing the need to modify PATH makes Conda much less disruptive to other software on your system.
In the old days, \path\to\anaconda3\Scripts is the one to be put into your PATH. It exposes command conda and the default Python from "base" environment at the same time.
After conda 4.6, conda related commands are separated into condabin. This makes it possible to expose ONLY command conda without activating the Python from "base" environment.
References
Conda 4.6 Release
How do I prevent Conda from activating the base environment?
When you install anaconda on windows now, it doesn't automatically add Python or Conda.
If you don’t know where your conda and/or python is, you type the following commands into your anaconda prompt
Next, you can add Python and Conda to your path by using the setx command in your command prompt.
Next close that command prompt and open a new one. Congrats you can now use conda and python

The newest version of the Anaconda installer for Windows will also install a windows launcher for "Anaconda Prompt" and "Anaconda Powershell Prompt". If you use one of those instead of the regular windows cmd shell, the conda command, python etc. should be available by default in this shell.
If you want to use Anaconda in regular cmd on windows you need to add several paths to your Path env variable.
Those paths are (instead of Anaconda3 the folder may be Anaconda2 depending on the Anaconda version on your PC):
\Users\YOUR_USER\Anaconda3
\Users\YOUR_USER\Anaconda3\Library\mingw-w64\bin
\Users\YOUR_USER\Anaconda3\Library\usr\bin
\Users\YOUR_USER\Anaconda3\Library\bin
\Users\YOUR_USER\Anaconda3\Scripts
\Users\YOUR_USER\Anaconda3\bin
I had also faced the same problem just an hour back. I was trying to install QuTip Quantum Toolbox in Python
Unfortunately, I didn't stumble onto this page in time.
Say you have downloaded Anaconda installer and run it until the end.
Naively, I opened the command prompt in windows 10 and proceded to type the following commands as given in the qutip installation docs.
conda create -n qutip-env
conda config --append channels conda-forge
conda install qutip
But as soon as I typed the first line I got the following response
conda is not recognized as an internal or external command, operable program or batch file
error messsage
I went ahead and tried some other things as seen in this figures
error message
Finally after going through a number conda websites, I understood how one fixes this problem.
Type Anaconda prompt in the search bar at the bottom like this (same place where you hail Cortana)
Anaconda prompt
Once you are here all the conda commands will work as usual
If you have installed Visual studio 2017 (profressional)
The install location:
C:\ProgramData\Anaconda3\Scripts
If you do not want the hassle of putting this in your path environment variable on windows and restarting you can run it by simply:
C:\>"C:\ProgramData\Anaconda3\Scripts\conda.exe" update qt pyqt
You need to add the python.exe in C://.../Anaconda3 installation file as well as C://.../Anaconda3/Scripts to PATH.
First go to your installation directory, in my case it is installed in C://Users/user/Anaconda3 and shift+right click and press "Open command window here" or it might be "Open powershell here", if it is powershell, just write cmd and hit enter to run command window. Then run the following command setx PATH %cd%
Then go to C://Users/user/Anaconda3/Scripts and open the command window there as above, then run the same command "setx PATH %cd%"
To prevent having further issues with SSL you should add all those to Path :
SETX PATH "%PATH%;C:\<path>\Anaconda3;C:\<path>\Anaconda3\Scripts;C:\<path>\Anaconda3\Library\bin"
Requests (Caused by SSLError("Can't connect to HTTPS URL because the SSL module is not available.") Error in PyCharm requesting website
case #1
You should set 3 path:
%ANACONDAPATH%;
%ANACONDAPATH%\Scripts;
%ANACONDAPATH%\Library\bin;
It will solve problem:
C:\WINDOWS\system32>conda update conda
Solving environment: failed
CondaHTTPError: HTTP 000 CONNECTION FAILED for url <https://repo.anaconda.com/pkgs/msys2/noarch/repodata.json.bz2>

Also you can use Anaconda Promd (for Win10) instead CLI (cmd.exe)
According to the official documentation, for Windows users there are two environment variable PATHs which can be updated, depending on how your Miniconda/Anaconda distribution has been installed -- one is the SYSTEM PATH, the other is the USER PATH: https://docs.conda.io/projects/conda/en/master/user-guide/tasks/manage-environments.html#activating-an-environment
Basically it says the following: If like the official recommendation you have installed conda for yourself on the user level only, you can add a path similar to C:\Users\<user-name>\miniconda3\Scripts to the user variables.
Please remember to change to Anaconda if you are not using miniconda and update the to your system username in order for this to work.
However, if you have a system level install for all users on the same machine, you should add the path c:\miniconda3\Scripts\ to the system variables.
Also, please run conda init in your PowerShell to have conda working on your PowerShell. If there is a Python version already installed on your PC, you can disable "app execution aliases" in Settings (under "Manage app execution aliases") for this to use only the Python ones on the command line to avoid conflict.
Even I got the same problem when I've first installed Anaconda. It said 'conda' command not found.
So I've just setup two values[added two new paths of Anaconda] system environment variables in the PATH variable which are: C:\Users\mshas\Anaconda2\ & C:\Users\mshas\Anaconda2\Scripts
Lot of people forgot to add the second variable which is "Scripts" just add that then conda command works.
I installed Anaconda3 4.4.0 (32 bit) on my Windows 7 Professional machine and imported NumPy and Pandas on Jupyter notebook so I assume Python was installed correctly. But when I type conda list and conda --version in command prompt, it says conda is not recognized as internal or external command.
I have set environment variable for Anaconda3; Variable Name: Path, Variable Value: C:\Users\dipanwita.neogy\Anaconda3
How do I make it work?
I was faced with the same issue in windows 10, Updating the environment variable following steps, it's working fine.
I know It is a lengthy answer for the simple environment setups, I thought it's may be useful for the new window 10 users.
1) Open Anaconda Prompt:
2) Check Conda Installed Location.
where conda
3) Open Advanced System Settings
4) Click on Environment Variables
5) Edit Path
6) Add New Path
C:\Users\RajaRama\Anaconda3\Scripts
C:\Users\RajaRama\Anaconda3
C:\Users\RajaRama\Anaconda3\Library\bin
7) Open Command Prompt and Check Versions
8) After 7th step type
conda install anaconda-navigator in cmd then press y
Although you were offered a good solution by others I think it is helpful to point out what is really happening. As per the Anaconda 4.4 changelog, https://docs.anaconda.com/anaconda/reference/release-notes/#what-s-new-in-anaconda-4-4:
On Windows, the PATH environment variable is no longer changed by default, as this can cause trouble with other software. The recommended approach is to instead use Anaconda Navigator or the Anaconda Command Prompt (located in the Start Menu under “Anaconda”) when you wish to use Anaconda software.
(Note: recent Win 10 does not assume you have privileges to install or update. If the command fails, right-click on the Anaconda Command Prompt, choose "More", chose "Run as administrator")
This is a change from previous installations. It is suggested to use Navigator or the Anaconda Prompt although you can always add it to your PATH as well. During the install the box to add Anaconda to the PATH is now unchecked but you can select it.
I found the solution.
Variable value should be C:\Users\dipanwita.neogy\Anaconda3\Scripts
When you install anaconda on windows now, it doesn't automatically add Python or Conda to your path.
While during the installation process you can check this box, you can also add python and/or python to your path manually (as you can see below the image)
If you don’t know where your conda and/or python is, you type the following commands into your anaconda prompt
where python
where conda
Next, you can add Python and Conda to your path by using the setx command in your command prompt (replace C:\Users\mgalarnyk\Anaconda2 with the results you got when running where python and where conda).
SETX PATH "%PATH%;C:\Users\mgalarnyk\Anaconda2\Scripts;C:\Users\mgalarnyk\Anaconda2"
Next close that command prompt and open a new one. Congrats you can now use conda and python
Source: https://medium.com/#GalarnykMichael/install-python-on-windows-anaconda-c63c7c3d1444
Just to be clear, you need to go to the controlpanel\System\Advanced system settings\Environment Variables\Path,
then hit edit and add:
C:Users\user.user\Anaconda3\Scripts
to the end and restart the cmd line
In addition to adding C:\Users\yourusername\Anaconda3 and C:\Users\yourusername\Anaconda3\Scripts, as recommended by Raja (above), also add C:\Users\yourusername\Anaconda3\Library\bin to your path variable. This will prevent an SSL error that is bound to happen if you're performing this on a fresh install of Anaconda.
If you have a newer version of the Anaconda Navigator, open the Anaconda Prompt program that came in the install. Type all the usual conda update/conda install commands there.
I think the answers above explain this, but I could have used a very simple instruction like this. Perhaps it will help others.
Go To anaconda prompt(type "anaconda" in search box in your laptop). type following commands
where conda
add that location to your environment path variables. Close the cmd and open it again
This problem arose for me when I installed Anaconda multiple times. I was careful to do an uninstall but there are some things that the uninstall process doesn't undo.
In my case, I needed to remove a file Microsoft.PowerShell_profile.ps1 from ~\Documents\WindowsPowerShell\. I identified that this file was the culprit by opening it in a text editor. I saw that it referenced the old installation location C:\Anaconda3\.
For conda --version greater than 4.6, from the base of your Anaconda promt, run
conda update conda
conda init
This will update your conda root environment and setup the stuff you need to run it on both cwd and powershell.
After this, you can start any terminal and it will be conda ready.
If you don't want to add Anaconda to env. path and you are using Windows try this:
Open cmd;
Type path to your folder instalation. It's something like:
C:\Users\your_home folder\Anaconda3\Scripts
Test Anaconda, for exemple type conda --version.
Update Anaconda: conda update conda or conda update --all or conda update anaconda.
Update Spyder:
conda update qt pyqt
conda update spyder
I have Windows 10 64 bit, this worked for me,
This solution can work for both (Anaconda/MiniConda) distributions.
First of all try to uninstall anaconda/miniconda which is causing problem.
After that delete '.anaconda' and '.conda' folders from 'C:\Users\'
If you have any antivirus software installed then try to exclude all the folders,subfolders inside 'C:\ProgramData\Anaconda3\' from
Behaviour detection.
Virus detection.
DNA scan.
Suspicious files scan.
Any other virus protection mode.
*(Note: 'C:\ProgramData\Anaconda3' this folder is default installation folder, you can change it just replace your excluded path at installation destination prompt while installing Anaconda)*
Now install Anaconda with admin privileges.
Set the installation path as 'C:\ProgramData\Anaconda3' or you can specify your custom path just remember it should not contain any white space and it should be excluded from virus detection.
At Advanced Installation Options you can check "Add Anaconda to my PATH environment variable(optional)" and "Register Anaconda as my default Python 3.6"
Install it with further default settings. Click on finish after done.
Restart your computer.
Now open Command prompt or Anaconda prompt and check installation using following command
conda list
If you get any package list then the anaconda/miniconda is successfully installed.
I have just launched anaconda-navigator and run the conda commands from there.
For those who didn't check "Add Anaconda to my PATH environment variable". In Windows 10 it looks like that:
5 paths:
C:\Users\shtosh\anaconda3
C:\Users\shtosh\anaconda3\Library\mingw-w64\bin
C:\Users\shtosh\anaconda3\Library\usr\bin
C:\Users\shtosh\anaconda3\Library\bin
C:\Users\shtosh\anaconda3\Scripts
if you use chocolatey, conda is in C:\tools\Anaconda3\Scripts
I had this problem in windows. Most of the answers are not as recommended by anaconda, you should not add the path to the environment variables as it can break other things. Instead you should use anaconda prompt as mentioned in the top answer.
However, this may also break. In this case right click on the shortcut, go to shortcut tab, and the target value should read something like:
%windir%\System32\cmd.exe "/K" C:\Users\myUser\Anaconda3\Scripts\activate.bat C:\Users\myUser\Anaconda3
