Anaconda won't update spyder - python

I had Spyder 3.1.3 installed an running fine.
Then I heard about "anaconda navigator" - which I never had launched it before - so I launched it, took a look around, installed glueviz and quit.
Next time I opened spyder - not from the navigator, from the shortcut I've always used (with this command: C:\Anaconda2\pythonw.exe C:\Anaconda2\cwp.py C:\Anaconda2 "C:/Anaconda2/pythonw.exe" "C:/Anaconda2/Scripts/spyder-script.py" --new-instance), it launched spyder version 2.3.8.
Then I went to the command line and tried to update spyder with the conda update spydercommand and I get this:
C:\>conda update spyder
Fetching package metadata ...........
Solving package specifications: .
# All requested packages already installed.
# packages in environment at C:\Anaconda2:
#
spyder 2.3.8 py27_1
C:\>
nothing happens.
If I try to update it from the navigator (running as admin), I get an error saying "spyder cannot be installed on this environment"
Any ideas what can I do to properly update spyder?
EDIT:
I updated pandas and skpyder downgraded to version 2.2.0...
Thanks

With admin privilege type (if one does not uninstall before installing it gets 'stuck' for hours)
conda uninstall spyder
conda install spyder=5.1.5

Update kernel modules after Spyder update

I updated my Spyder today to Spyder 5.1, and now it keeps showing me this error message:
Your Python environment or installation doesn't have the spyder‑kernels module or the right version of it installed (>= 2.1.0 and < 2.2.0). Without this module is not possible for Spyder to create a console for you.
You can install it by running in a system terminal:
conda install spyder‑kernels=2.1
or
pip install spyder‑kernels==2.1.*
I already tried both commands, the pip one works but I still get the error message, the conda command does not even work and shows me
The following packages are not available from current channels
Normally I use conda for all packages that are availabel on conda, so maybe someone faced the same issue?
Version 2.1 is only available through Conda Forge at this time. Try
conda install -c conda-forge spyder-kernels=2.1
So far I've had to remove spyder-kernels from any env from any env that has it before I'm able to get it to install on any other env. I'm using conda. It seems I can't have more than one env available for use without constantly swapping where spyder-kernels is installed. This is the case for Windows 10 and MacOS. The spyder docs say to just ignore the issue - and that it was allegedly fixed by now - but I don't know how to ignore an error that makes it impossible to start a python console.
Correction: After erasing all envs and starting over from scratch (zero envs), I am now able to install spyder-kernels on multiple newly-created envs and each one functions in console without an issue.

keeping Spyder updated in Anaconda

have Anaconda installed on a win-10 box and I am using Spyder 4.1.5
to sume up: need to get more insights on how to keep VSCode and Spyder updated .. Can i do that via Conda!? Look forward to hear from you.
well i Would like to update Spyder to the latest version, so I went through the commands:
conda update conda
conda update anaconda
conda update spyder
They all ran without errors, but the spyder version didn't change - this is command I'm using to launch:
Well - i allways thougth that if we want to update Spyder in the root environment, then the following command conda update spyder works
If we want to update Spyder for a virtual environment we have created (e.g., for a different version of Python), then conda update -n $ENV_NAME spyder where $ENV_NAME is our environment name.
how to indicate what is going on here?
should i run conda update anaconda before updating spyder.
well - i thought that i have to make sure i am in the base directory.
here conda install spyder should work.
I have tried also this: conda install spyder=new_version_number.
new_version_number should be in digits.
btw: i had a view on the official docs here: code.visualstudio.com/docs/python/debugging.
In brief, i tried the 'Add Configuration' Button. But i guess i have a screwd up installation &/ configuration.
do i need these steps too!?

Efficient Way to Activate Conda in VSCode

update: its obviousliy the Anaconda-channeling-thing that stands sometimes in the way. - at least in regard of spyder-updates
cf. Why is Conda not installing/updating the latest version of Spyder?
Why is Conda not installing/updating the latest version of Spyder?
But those bug reports and "solutions" were made one year ago. Spyder
is on later versions now. Why is conda still installing Spyder version
4.0.1, with all the issues, one year after 4.0.1 is known to be problematic? Why does it not update correctly to any later version?
The latest version is supposed to be 5.0.0, with even 4.2.* rolled out
before that.
The problem is with the Anaconda channel.
I uninstalled Spyder and then install with the line:
conda install spyder and Spyder 5.0.0 was successfully installed.
Anaconda's Spyder page (https://anaconda.org/anaconda/spyder) gave the
command as:
conda install -c anaconda spyder which led to the installation of
Spyder 4.0.1, instead of 5.0.0 which was what it was supposed to
install as documented on the page itself.
note: i will have a closer look if this behavior is the same - in regard of updating the VSCode!?
update:
i guess that i have to take care for the following steps
• Check and test conda is installed and available
• see if i need an Update conda if necessary
• Create the great virtual environment
• Activate a virtual environment - with all the tests that we can apply now
to sume up: need to get more insights on how to keep VSCode and Spyder updated .. Can i do that via Conda!? Look forward to hear from you.
Visual Studio Code has an auto-update for Windows and Mac:
Quote from vs code faq:
... By default, VS Code is set up to auto-update for macOS and Windows users when we release new updates. If you do not want to get automatic updates, you can set the Update: Mode setting from default to none.
To modify the update mode, go to File > Preferences > Settings (macOS: Code > Preferences > Settings), search for update mode and change the setting to none. ...
Regarding anaconda, your commands seem fine.
conda update conda
conda update spyder
Should work. Just make sure you have activated your environment.
For more info on conda updates, please refer to official page.

How to instal Python packages for Spyder

I am using the IDE called Spyder for learning Python.
I would like to know in how to go about in installing Python packages for Spyder?
step 1. First open Spyder and click Tools --> Open command prompt.
For more details click visit this link,
https://miamioh.instructure.com/courses/38817/pages/downloading-and-installing-packages
I am running Spyder 4.2.4 and for me following solution turned out to be working:
open tools-> preferences -> python interpreter
click 'use the following python interpreter'
point the location to local python installation, in my case : C:\Users\MYUSER\AppData\Local\Programs\Python\Python37\python.exe
Click OK and restart the kernel.
Now the pip started to work and I was able to import any package I previously installed on the cmd/python CLI.
Spyder is a package too, you can install packages using pip or conda, and spyder will access them using your python path in environment.
Spyder is not a package manager like conda,, but an IDE like jupyter notebook and VS Code.
For the latest versions of Spyder use this console
at right bottom
Note: Once you hit enter it may take some time to install and you can't see the progress until it finishes.
Else:
Open anaconda command prompt
Activate your environment: conda activate env-name
Install the package: conda install your-package-name
I have not checked if the ways described by people here before me work or not.
I am running Spyder 5.0.5, and for me below steps worked:
Step 1: Open anaconda prompt (I had my Spyder opened parallelly)
Step 2: write - "pip install package-name"
Note: I got my Spyder 5.0.5 up and running after installing the whole Anaconda Navigator 2.0.3.
I installed Basic Python IDLE(python 3.9)
As I used to Spyder. I installed a standalone Spyder from https://www.spyder-ide.org/
Then I faced problems for packages
I tried this one
pip install spyder spyder-terminal

Spyder will not launch from Anaconda 2019.10 Navigator

After a fresh installation of Anaconda 2019.10, I'm unable to launch Spyder straight out of the box. I'm surprised to see this error upon launching Spyder from the Anaconda toolbar:
File "C:\Users\ME\AppData\Roaming\Python\Python37\site-packages\spyder\requirements.py", line 24, in show_warning raise RuntimeError(message) RuntimeError: Please check Spyder installation requirements: spyder-kernels >= 1.0 is required (found 0.5.2).
I thought this would do the trick:
conda install -c conda-forge spyder-kernels
But the same error is still being raised
In Anaconda click on environments. Select the environment you want to use. When that environment loads. Then go to Home. When home loads go to Spyder icon. If it says install within the icon then click on install. Spyder is not automatically installed for all environments. You have to install it for each environment in Anaconda. I am surprised an update would cause a problem but perhaps the above procedure might correct the problem.

how to update spyder on anaconda

I have Anaconda installed (Python 2.7.11 |Anaconda custom (64-bit)| (default, Feb 16 2016, 09:58:36) [MSC v.1500 64 bit (AMD64)] on win32) and I am using Spyder 2.3.8
Would like to update Spyder to the latest version, so I went through the commands:
conda update conda
conda update anaconda
conda update spyder
They all ran without errors, but the spyder version didn't change - this is command I'm using to launch:
C:\Anaconda2\pythonw.exe C:\Anaconda2\cwp.py C:\Anaconda2 "C:/Anaconda2/pythonw.exe" "C:/Anaconda2/Scripts/spyder-script.py" --new-instance
Am I missing something?
To expand on juanpa.arrivillaga's comment:
If you want to update Spyder in the root environment, then conda update spyder
works for me.
If you want to update Spyder for a virtual environment you have created (e.g., for a different version of Python), then conda update -n $ENV_NAME spyder where $ENV_NAME is your environment name.
EDIT: In case conda update spyder isn't working, this post indicates you might need to run conda update anaconda before updating spyder. Also note that you can specify an exact spyder version if you want.
Go to Anaconda Naviagator, find spyder,click settings in the top right corner of the spyder app.click update tab
I see that you used pip to update. This is strongly discouraged (at least in Spyder 3). The Spyder update notices I receive have always included the following:
"IMPORTANT NOTE: It seems that you are using Spyder with Anaconda/Minconda. Please don't use pip to update it as that will probably break your installation. Instead please wait until new conda packages are available and use conda to perform the update."
Use this conda install spyder=4.0.0
This will not mess up your anaconda dependencies.
https://github.com/spyder-ide/spyder/releases
Simply select 'Update Application' after clicking on the settings symbol(top right corner) for Spyder in the Anaconda Navigator console. In my case I just updated it so it's in disabled state.
use this command
conda install spyder=5.0.1
this will install the new version or tell you the error
PackagesNotFoundError: The following packages are not available from
current channels
How to solve the error
1- update your anaconda
conda update anaconda
2- go to anaconda then spyder
or use this command
conda install spyder=5.0.0
make sure you in your base directory.
then conda install spyder will work.
Do it like this: conda install spyder=new_version_number.
new_version_number should be in digits.
One way to avoid errors during installing or updating packages is to run the Anaconda prompt as Administrator. Hope it helps!
You can easily install update version if you use Anaconda by closing Spyder and then running the following command in a system terminal (Anaconda Prompt on Windows, xterm on Linux or Terminal.app on macOS):
conda install spyder= Your desire version
(For example, Version is 3.1)
conda install spyder=3.1
Or you can use pip with this command in a system terminal (cmd.exe on Windows, xterm on Linux or Terminal.app on macOS):
pip install --pre -U spyder
Note: Do not use this command if you are using Anaconda because it could break your installation.
Using pip directly:
WARNING: This will break your Anaconda Installation as described by Spyder maintainer in the comments below; you can try this solution only if the solution mentioned above that use Conda do not work
pip install --upgrade spyder
You might get an error once launching the new Spyder "nbconvert >= 4.0: None (NOK)", which will require you to resinstall configparser:
conda uninstall configparser
conda install configparser
You should now have a fresh and up to date installation of Spyder.
In iOS,
Open Anaconda Navigator
Launch Spyder
Click on the tab "Consoles" (menu bar)
Then, "New Console"
Finally, in the console window, type conda update spyder
Your computer is going to start downloading and installing the new version. After finishing, just restart Spyder and that's it.
It's very easy just in 2 click
Open Anaconda Navigator
Go to Spyder icon
Click on settings logo top-right coner of spider box
Click update application
That it
Happy coding
My solution was uninstalla spyder and installa again.
Solved my problem:
conda uninstall spyder
conda install spyder=5
