command 'python.setInterpreter' not found when using code-server > 3.4.1

[yijingru]

Hi,

I think my code-server updates the python version (2020.6.88468) automatically, and yesterday I cannot add the python interpreter, the command windows outputs:

Command 'Python: Select Interpreter' resulted in an error (command 'python.setInterpreter' not found)

I rolled back the python version, but it does not help. For example, python2020.5.80290 can add the interpreter, but it raises another problem of the debugger

Error: The number of constructor arguments in the derived class s must be >= than the number of constructor arguments of its base class.
    at /root/.local/share/code-server/extensions/ms-python.python-2020.5.80290/out/client/debugger/debugAdapter/main.js:16:49625

The following information is the coder-server version and vs code version:

code-server: v3.4.1
VS Code: v1.45.1

[frozen-icecube]

The title of the jira should be constructor args mismatch causing debug adapter to fail and not being able to load debugger for python.

I have now tried code-server version 3.2.0, 3.3.1 and 3.4.1 with various combinations of ms-python versions.

ms-python 2020.6.88468 does not even load. So i tried with all the way back down to 2020.3.69010. The older versions load but they are getting the mismatched constructor args issue.

Does anyone know what changed in ms-python / language server as code-server 3.3.1 was working fine along with older 2020.5.x version of ms-python?

Is this potentially due to debugpy related switch or an inversifyjs issue ?

I even tried with using the latest node-v14.4.0 but that also does not help...

Actual error :

Error: The number of constructor arguments in the derived class s must be >= than the number of constructor arguments of its base class.

Thanks for any suggestions...

Also raised a jira on code-server side : coder/code-server#1821

The rollback issue was because of a bug which opted users out of experiments. It should be fixed now with da85a76
Reload to activate the extension again, which will download the fresh experiments. Then reload again and the extension will be activated using the new experiments.

[yijingru]

Thank you @karrtikr, the python extension 5.86806 now is good. But the newest version 6.89148 still has the problem of Error: The number of constructor arguments in the derived class s must be >= than the number of constructor arguments of its base class, and the previous version 6.89468 cannot load the python interpreter. But anyway, I can use 5.86806 instead. Thanks a lot!!

[frozen-icecube]

I found a solution. You have to move to code-server 3.4.1 and then downgrade ms-python to 2020.5.x and all will be good.

[yijingru]

@gauravk88 thanks.

[karrtikr]

Reopened because we would like to get to the bottom of the issue

[kimadeline]

Hi @yijingru and @gauravk88,

Can you copy the output for Python in the Output panel (View→Output, change the drop-down the upper-right of the Output panel to Python) when you're on the latest version of the Python extension (2020.6.89148)?

Can you also check if you have multiple versions of the Python extension installed and delete the old ones (in /root/.local/share/code-server/extensions/)?

Thanks!

[yijingru]

Hi @kimadeline, the python extension 2020.6.89148 raises error Command 'Python: Select Interpreter' resulted in an error (command 'python.setInterpreter' not found) so I don't have the Python in the Output panel for this version. This issue is different from the debugger problem this morning. The same problem for 2020.6.88468, 2020.5.2.

@kimadeline So to recreate the issue simply take code-server version 3.3.1 and install the latest version of ms-python extension available in marketplace in code-server : 2020.6.89148.

I have no other extension installed and when i reload the screen to activate ms-python extension i get an error when i try to discover tests

The error is : Command 'Python: Discover Tests' resulted in an error (command 'python.discoverTests' not found)

The python log is as given below :

> conda --version
> pyenv root
> conda info --json
Python interpreter path: /usr/bin/python

Please let me know, if you want me to debug this through further..

Also, the arguments mismatch error is different and happening on all code-server versions except the latest version 3.4.1 : https://github.com/cdr/code-server/releases/download/v3.4.1/code-server-3.4.1-linux-amd64.tar.gz even with ms-python 2020.5.86806

If you upgrade code-server to 3.4.1 and downgrade ms-python to 2020.5.86806 then everything is fine.

Thanks,
Gaurav

Thank you both for your replies! I'll mark the issue as a regression, and in the meantime feel free to upvote the original comment to help us prioritize this fix.

I can confirm it's still an issue with version 2020.6.90262 of the Python extension, and the latest version of code-server (3.4.1).

Repro steps:

• Install code-server (instructions here), I did it in a Docker instance:
  • Open an existing Python workspace in a Docker container
  • Call the code-server install script from the terminal there
• Launch code-server (just type code-server in the terminal), access the instance in the browser and open a Python file to try and activate the extension
• Open the browser developer tools, this error appears (happens during activation):

Failure during activation. [Error: The number of constructor arguments in the derived class o must be >= than the number of constructor arguments of its base class.

Running any command associated to the Python extension afterwards will fail with a Command not found because the extension didn't activate properly.

Notes:

• Might be related to our DI (see number of constructor arguments must be >= ... the base class - when not overriding constructor inversify/InversifyJS#729)
• If running git bisect to build VSIX files and load them, the last working version of the extension was 2020.5.86806, it broke in 2020.6.88468.

[ZandercraftGames]

@ZandercraftGames do you have the 'ms-toolsai.jupyter extension installed?

It is in the error message:

Cannot activate extension 'Python' because it depends on extension 'ms-toolsai.jupyter'

Yes, I do have it installed. When installing the Python extension, it automatically installs Jupyter and wont let you uninstall it as it is a dependancy of Python. I also tried uninstalling the Python and Jupyter extensions, then installing Jupyter on it's own and then the Python extension after to no avail.

[kimadeline]

Thank you for the clarification 🙂 Could you open a separate issue for your problem? If it turns out it has the same root as this one we'll fold them back together.

Thanks!

[ITmind]

installing version 2020.10.332292344 solves the problem

[meilier]

code-server 3.4.1 and then downgrade ms-python to 2020.5.x works, any information about the new version?

[LVerneyPEReN]

In case this can be useful (I did not see mentions of code-server >= 3.5), I can reproduce the issue in code-server v3.7.4 (vscode v1.51.1) / ms-python v2021.1.502429796.

[Whitie]

I can reproduce the issue also with code-server 3.8.0 (vscode 1.51.1 / ms-python v2021.1.502429796). It's on Arch Linux if this matters.

[ghost]

I installed code-server manually (so not with docker basically) and i'm using python3 in the console to call python and run my apps
For example : python3 ./something.py

[conan-ed]

Same problem with code-server in docker version with newest python extension 2021.2.633441544:
code-server: v3.9.1
VS Code: v1.53.2
I suspect the problem come from extension Jupyter which is required by newest python ext.
Uninstall python ext then install older version v2020.10.332292344 using vsix fix this problem (disable ext auto update first).

Yes the problem is not solved. The only solution is to use ms-python 2020.10.332292344 version...

[karrtikr]

The following comment dated Jun 18, 2021 coder/code-server#1837 (comment) states this is no longer an issue with latest versions of Jupyter and Python extension, the latest comment on this issue was on Mar 9, 2021. Can anyone confirm if this is still an issue?

[karrtikr]

Unfortunately I'm unable to reproduce the issue using the instructions in Docker here: https://coder.com/docs/code-server/latest/install#docker.

@japita-se Can you describe how you installed & launched the code-server? Please also paste the logs and errors you see. Make sure you're using the latest version of VSCode and code-server. (Run code-server --version to find out the version)

[karrtikr]

Because we have not heard back with the information we requested, we are closing this issue for now. If you are able to provide the info later on then we will be happy to re-open this issue to pick up where we left off.
