I'm not a Python user, so know little about Python. But I have to install stcgal using pip3 following its official guide.
pip3 install stcgal
However, if I run the installed command in terminal, it says zsh: command not found.
After a long searching, I find it was installed at /Users/myUserName/Library/Python/3.8/bin/. Though I can run the command with that path, it's very inconvenient. I wonder is there any way to run the code in any directory instead having to locate it explicitly?
Try something like this:
python -m stcgal -h
You can create or edit your /Users/yimingliu/.zshrc file (if your macOS is older than macOS Catalina 10.15, then the file is /Users/yimingliu/.bash_profile), and add a line to add the python bin folder to your path:
export PATH=/Users/yimingliu/Library/Python/3.8/bin:$PATH
I'm running into a weird error when trying to install Django on my computer.
This is the sequence that I typed into my command line:
C:\Python34> python get-pip.py
Requirement already up-to-date: pip in c:\python34\lib\site-packages
Cleaning up...
C:\Python34> pip install Django
'pip' is not recognized as an internal or external command,
operable program or batch file.
C:\Python34> lib\site-packages\pip install Django
'lib\site-packages\pip' is not recognized as an internal or external command,
operable program or batch file.
What could be causing this?
This is what I get when I type in echo %PATH%:
C:\Python34>echo %PATH%

You need to add the path of your pip installation to your PATH system variable. By default, pip is installed to C:\Python34\Scripts\pip (pip now comes bundled with new versions of python), so the path "C:\Python34\Scripts" needs to be added to your PATH variable.
To check if it is already in your PATH variable, type echo %PATH% at the CMD prompt
To add the path of your pip installation to your PATH variable, you can use the Control Panel or the setx command. For example:
setx PATH "%PATH%;C:\Python34\Scripts"
Note:
According to the official documentation, "[v]ariables set with setx variables are available in future command windows only, not in the current command window". In particular, you will need to start a new cmd.exe instance after entering the above command in order to utilize the new environment variable.
Thanks to Scott Bartell for pointing this out.
For Windows, when you install a package, you type:
python -m pip install [packagename]
As of now, version 3.7.3 I had a little bit of an issue with getting the right system variable.
Try this:
Type start %appdata% in cmd.
After that file explorer should pop up in ../AppData/Roaming.
Go back one directory and navigate to Local/Programs/Python/Python37-32/Scripts.
NOTE: The version number may be different so if you copy and paste the above file path it could not work.
After you do this you now have the correct location of your downloaded Python. Copy your file path by selecting the whole directory in the address bar.
Once you do that click the start icon and navigate to the Control Panel → System and Security → System. Then click "Advanced System Settings" on the left side of the panel.
Once there, click Environment Variables on the bottom right and there will be two boxes, an upper and a lower box. In the upper box: Click on the 'Path' Variable and click Edit located on the right. Click New and paste your directory Path. It should look something like this:
Click OK three times, open a new window of cmd and type: pip. See if it works.
For me the command:
set PATH=%PATH%;C:\Python34\Scripts
worked immediately (try after echo %PATH% and you will see that your path has the value C:\Python34\Scripts).
Thanks to: Adding a directory to the PATH environment variable in Windows
Alternate way.
If you don't want to add the PATH as the previous well written answers pointed out,
but you want to execute pip as your command then you can do that with py -m as prefix.
Given that you have to do it again and again.
eg.
py -m <command>
as in
py -m pip install --upgrade pip setuptools
Also make sure to have pip and py installed
The only way that worked on my Windows 10 machine was as follows:
py -3 -m pip install xxxxx
Also, the long method - it was a last resort after trying all previous answers:
C:\python27\scripts\pip.exe install [package].whl
This after cd in directory where the wheel is located.
As per Python 3.6 Documentation
It is possible that pip does not get installed by default. One
potential fix is:
python -m ensurepip --default-pip
Control Panel -> add/remove programs -> Python -> Modify -> optional Features (you can click everything) then press next -> Check "Add python to environment variables" -> Install
And that should solve your path issues, so jump to command prompt and you can use pip now.
Go to control Panel >> Uninstall or change Program and double click on Python XXX to modify install. Make sure PIP component is checked and install.
I was having the same problem just now.
After adding the proper folder (C:\Python33\Scripts) to the path, I still could not get pip to run. All it took was running
pip.exe install -package- instead of
pip install -package-.
Try going to Windows PowerShell or cmd prompt and typing:
python -m pip install openpyxl
In latest version Python 3.6.2 and above, is available in
C:\Program Files (x86)\Python36-32\Scripts
You can add the path to our environment variable path as below
Make sure you close your command prompt or Git after setting up your path. Also should you open your command prompt in administrator mode. This is example for Windows 10.
Use
set Path = `%PATH%;C:\Python34\;C:\Python27\Scripts`
Source
Or if you are using PyCharm (2017-03-03) like me, just change directory in terminal and install:
cd C:\Users\{user}\PycharmProjects\test\venv\Scripts
pip install ..
Most frequently it is:
in cmd.exe write
python -m pip install --user [name of your module here without brackets]
Even I'm new to this, but pip install django worked for me.
The path should be set as where the script folder of the Python installation is, i.e.C:\Python34\Scripts.
I suppose it's because Django is a framework which is based on Python, and that's why this directory structure has to be maintained while installing.
I have just installed Python 3.6.2.
I got the path as
C:\Users\USERNAME\AppData\Local\Programs\Python\Python36-32\Scripts
In Windows, open cmd and find the location of PYTHON_HOME using where python. Now add this location to your environment variable PATH using:
set PATH=%PATH%;<PYTHON_HOME>\Scripts
Or refer to this.
In Linux, open a terminal and find the location of PYTHON_HOME using which python. Now add the PYTHON_HOME/Scripts to the PATH variable using:
PATH=$PATH:<PYTHON_HOME>\Scripts
export PATH
You can try pip3. Something like:
pip3 install pandas
I was facing the same issue. Run Windows PowerShell as Administrator. It resolved my issue.
None of these actually worked for me, but running
python -m pip install -U pip
and then adding the specified directory to the PATH as suggested got it working
In your Python folder path in Terminal, just type
py -m pip
in order to check the current version of your pip.
You will also see a list of commands, you can use...
I think from Python 2.7.9 and higher pip comes pre installed and it will be in your scripts folder.
So you have to add the "scripts" folder to the path. Mine is installed in C:\Python27\Scripts. Check yours to see what your path is so that you can alter the below accordingly. Then go to PowerShell, paste the below code in PowerShell and hit Enter key. After that, reboot and your issue will be resolved.
[Environment]::SetEnvironmentVariable("Path", "$env:Path;C:\Python27\Scripts", "User")
In a Windows environment, just execute the below commands in a DOS shell.
path=%path%;D:\Program Files\python3.6.4\Scripts;
(new path=current path;path of the Python script folder)
I deleted the older version using the control panel and then installed the new version however the newer version was not reflecting pip even after adding the right paths in the environment variables. However, the thing that worked for me was deleting the folders of old python that were there in the local App folder even after uninstall. For me, the path was like below. Deleting this folder solved my issue
C:\Users\username\AppData\Local\Programs\Python38
'pip' is not recognized as an internal or external command
pip is a python module used to install packages. For your problem, there can be many reasons;
Restart CMD/Terminal
Environment variable is not set. pip is installed but environment variable is not set. Environment variable is a windows variable where pip path is saved, so it can be run at run time.
pip is not installed.
Restart CMD/Terminal
It is sometimes possible that you opened your command prompt or terminal before installing pip and now it just needs a restart to pick up the latest environment variables. It is worth trying just restarting your command prompt or terminal.
Environment Variable is Not Set
Open CMD and run this command to see the values set in the PATH environment variable.
echo %PATH%
This will echo the PATH environment variable like this;
You should check if your path exist in the echoed PATH list. For example, in my case, the path for pip.exe files is C:\Python310\Scripts. You can check this path yourself like this;
If you can find pip path and it does not exist the echoed PATH variable, then we need to add it. Copy the path like C:\Python310\Scripts.
Go to Start > This PC > Properties > Advance system settings >
Advanced > Environment Variables
As shown in the image above, Select Path, click Edit button and add the copied path. Restart the CMD and test pip command again.
pip is Not Installed
If pip is not installed, you can install it again by downloading latest python.exe setup from python.org website. Make sure you check mark the pip option as shown in the image below.
In the next step, check mark "Add Python to environment variables"
I had this same issue. You just need to go to your
C:\Python27\Scripts
and add it to environment variables. After path setting just run pip.exe file on C:\Python27\Scripts and then try pip in cmd. But if nothing happens try running all pip applications like pip2.7 and pip2.exe. And pip will work like a charm.
Small clarification: in "Windows 7 64 bit PC", after adding ...Python34\Scripts to the path variable, pip install pygame didn't work for me.
So I checked the "...Python34\Scripts" folder, it didn't have pip, but it had pip3 and pip3.4. So I ran pip3.4 install pygame .... .whl. It worked.
(Further open a command window in the same folder where you have the downloaded pygame...whl file.)
When installing SQL 2019 Python, there are known issues for PIP which require a fix (step 7)
https://learn.microsoft.com/en-us/sql/advanced-analytics/known-issues-for-sql-server-machine-learning-services?view=sql-server-ver15
pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.
Workaround
Copy the following files:
libssl-1_1-x64.dll
libcrypto-1_1-x64.dll
from the folder
C:\Program Files\Microsoft SQL Server\MSSSQL15.MSSQLSERVER\PYTHON_SERVICES\Library\bin
to the folder
C:\Program Files\Microsoft SQL Server\MSSSQL15.MSSQLSERVER\PYTHON_SERVICES\DLLs
Then open a new DOS command shell prompt.
I am installing Python 3.7.2 for the first time, and I'm using the VS Code python extension.
When I run python -V I get Python 2.7.10 which is not correct!
When I select the usr/local/bin/python3 interpreter in VS Code I get this error when running a script:
bash: /Users/erik/Work/Python/usr/local/bin/python3: No such file or directory
But when I look in usr/local/bin I can see that Python3 is there. I'm not sure why VS Code pastes the work directory in front of usr/local/bin ?
My first thought was that Python3 should be in the PATH variable so I ran the included Update Shell Profile command, which gives this feedback:
This script will update your shell profile when
the 'bin' directory of python is not early enough
of the PATH of your shell.
All right, you're a python lover already
Now, after rebooting VS Code I get a new option for selecting an interpreter:
/Library/Frameworks/Python.framework/Versions/3.7/bin/python3
Is that different from the Python in usr/local/bin ? When I select it, I get this error:
The script isort is installed in '/Users/erik/Library/Python/3.7/bin' which is not on PATH.
I also get this sideways related error:
You are using pip version 18.1. You should consider upgrading via the 'pip install --upgrade pip' command.
But, when following these instructions I get yet another error:
bash: pip: command not found
All in all, this process and the official documentation seem less than user-friendly? Apparently I'm required to dig deep through my mac's system files in the terminal before even writing one line of code.
Am I missing an essential step here?
I suggest that you use virtual environment for your project
first
pip install virtualenv
open cmd in your project directory that you open in VS-Code (it's important that vs-code sees this virtualenv folder that we will create)
mkvirtualenv my_env
and it will activate it automatically. if not run
my_env/bin/Scripts/activate or my_env/Scripts/activate
Then go open vs-code then select my_env for python interpreter
Well, if you want to change your default Python version for the whole system, it might break some applications that are depending on Python 2.
You can alias the commands by adding this line to your ~/.bash_profile:
$ alias python='python3'
The python command will now refer to python3.
If you want to execute the original Python (which refers to python2), you can escape the alias (so \python will launch python2 without touching the alias).
Btw.
$ unlink /usr/local/bin/python
$ ln -s /usr/local/bin/python3.7 /usr/local/bin/python
could also be a workaround for you.
I'm trying to run the autopep8 linter on a Python file in VSCode.
I've followed the instructions here: https://code.visualstudio.com/docs/python/environments and selected my interpreter (⇧⌘P): /usr/local/bin/python
I then try to format my code, and VSCode says autopep8 isn't installed, and can be installed via Pip. However, when I try to install via Pip, it says There is no Pip installer available in the selected environment.
I then tried launching a terminal in the current environment by selecting Python: Create Terminal from the Command Palette.
The terminal opens fine, pip is present, and I'm even able to pip install autopep8 in the terminal that opened in VSCode, but when I try running the Format Document command I get the same errors that autopep8 and pip aren't available in the environment.
On Ubuntu16.04, I worked with Python3 in vscode and
apt-get install python3-pip
solves my problem.
That's because I discover that: Under my terminal, I type the pip -V. It displays it's for Python2, not for Python3.
Man you can only change the interpreter.
Go in (ctrl + shift + p), then type Python: Select Interpreter, this way you choose the version that your extension needs.
This worked for me.
I have multiple python versions:
2.7
3.6
3.7
Tell the vscode/ visual studio code, which version to use:
press the following (Show All Commands): Ctrl + Shift + P
paste the following: Python: Select Interpreter
Select one of the version that it shows, I have selected python 3.7.3 64-bit
Update python path in settings:
press Ctrl + , to open Settings
search for python.pythonPath
change python to /usr/bin/python3.7
Note: this may not be needed, however, make sure /usr/bin/python3.7 really exists for you, you may have at a different path like /usr/local/bin/python3.7, etc.
I had pip but it was 2.7, but since I am choosing python 3, it's pip needs to be installed
Run the following command in Terminal: apt-get install python3-pip
Restart vscode
With the above steps, all issues got resolved. Hope that helps.
try Ctrl+Shift+P
then type
Python: Select Interpreter
and select the python version.
Installing python3-pip fixed the issue for me.
apt-get install python3-pip
1.Select the File > Preferences > Settings command (⌘,) to open your User Settings.
2.Search and Create or modify an entry for python.pythonPath with the full path to the Python executable according to your requirements.For Example i changed it to python2.6 path to this path /usr/local/bin/python3.
I had the same problem today, none of the solutions helped me. Eventually, I figured it out myself.
I'm posting this answer for people who are having this problem. Just go to your ./venv folder and you will find a .cfg file.
Just make sure include-system-site-packages is set to true
home = /usr/bin
include-system-site-packages = true
version = 3.8.5
If it still doesn't work, just run sudo install python3-pip once in the terminal. Of course you could always change the version here as well.
(on mac)if you are using python3 but vscode told you pip was not installed , you could change python version on vscode bottom.
And I guess you are using another terminal but not bash , vscode's default terminal is bash. Bash don't know you have install pip#2.
For WSL users:
If you have your work files in linux subsystem path, you still need pip for windows in order to VSCode to use it.
On Ubuntu:
Make sure, that you have Python and pip installed.
Go to Settings, type python.py in search input. This should find Python Path settings.
Remove this path (if it is currently setted), save. Exit Code and set this to current value.
For me is /usr/bin/python3
Had this issue when trying use autopep8. For me - it had nothing to do with pip (I know it is installed) but the path the VScode python extension was using.
If you open up the extension and go to it's setting and scroll down, there is a path you can designate for autopep8: Python › Formatting: Autopep8 Path
I used the path recommended by these docs:
https://code.visualstudio.com/docs/python/editing#_formatting
Which was: python.formatting.autopep8Args
I stopped getting the error.
For Windows system check the environment variable>System variables
check the Path variable for the python path.(if not found set the path variable for python)
Copy the path and paste under vscode>file>preferences>settings>python.pythonPath
It worked for me.
I ran into this problem while learning django and the terminal would not let me pip install anything.
Create a virtual environment in shell and then use the path of the environment as your interpreter. This worked for me.
Note: You might want to create to create the environment in a different shell altogether and then upload the folder of the environment into vscode.
Then you open up the settings file in the environment folder.
This image will hopefully give you a good idea. Click Here
I was having a similar problem with pylint in a docker container. I realized that the reason the VS-Code-prompted pylint install didn't work for me was because I was using the global python installation (global inside my docker container, anyway), which can require elevated permissions to install things and VS code wasn't running as root in the container. According to the vs code python extension docs:
Note: If you're using a global environment and VS Code is not running elevated, linter installation may fail. In that case, either run VS Code elevated, or manually run the Python package manager to install the linter at an elevated command prompt for the same environment: for example sudo pip3 install pylint (macOS/Linux) or pip install pylint (Windows, at an elevated prompt)
Go in (ctrl + shift + p), then type Python: Select Interpreter,
then type Python: Select Interpreter and then click on "Enter interpreter path"
Then click on "Find.. Browse your file. "
Then type Python in c drive search bar and click on latest version of python in case if you have multiple version of python. Enter and modify wait for sometimes to complete then close.
After that restart your vs code.
It worked for me it will work for you also.
Note: This is a solution for Windows.
First make Sure your Python is installed properly. Run the following command:
py --version
If the Previous command is running fine it will give you your python version. In that case go ahead and check if pip is present or not. Run the below command to check:
py -m pip
If pip is present in your system it show give you a list of option and info. If that's the case then go Ahead and run pip. All you need to do is precede the command you would normally write with py -m. For example:
pip install flask
py -m pip install flask
This should solve your problem.
I have installed python2 and python3 in my Mac osx and currently I'm using python3. And I am able to pip3 install virtualenv and virtualenvwrapper. The problem is whenever I restart my terminal, the settings for virtualenvwrapper don't work, like I can't use the commands mkvirtualenv and workon. The error I get is bash: the command workon is not found. I think there must be something wrong with my settings about the virtualenvwrapper. Here is what I try:
edit the ~/.bashrc:
export WORKON_HOME=~/Envs
source ~/Envs/django_projects/bin/virtualenvwrapper.sh
All my virtualenv packages are installed in the ~/Envs and after that, I source the .bashrc and it works, I could use workon and mkvirtualenv but once I reopen a new terminal it still could find't the workon command.
Does anyone know what's wrong with my setting?
After a few try, finally it works. There are two problems. The first one is because I have both python2 and python3 installed in my machine and by default the virtualenvwrapper try to run using the default python(in /usr/bin/python which is python2) so I have to change it to point to python3. So in my .bashrc file:
export WORKON_HOME=~/Envs
export VIRTUALENVWRAPPER_PYTHON=PATHS/TO/PYTHON3
source ~/Envs/django_projects/bin/virtualenvwrapper.sh
The second one is that .bashrc doesn't run automatically,we have to source in to ./bash_profile. Check https://apple.stackexchange.com/questions/12993/why-doesnt-bashrc-run-automatically for detail.
Then reopen the terminal and ta-da.
In order to be able to use virtualenvwrapper you need to source the script that is somewhere in /Users/mic4ael/Library/Python/{Python version}/bin/virtualenvwrapper.sh. So you could put source /Users/mic4ael/Library/Python/{Python version}/bin/virtualenvwrapper.sh to your .bashrc to make it every time you launch a terminal.
