the extension can not find the path of python from microsoft store

[mbtk]

Issue Type: Bug

I installed Python and everything works well. But after a VS update, every time I open VScode it says:"Python is not installed, please download and install...."

Extension version: 2020.3.69010
VS Code version: Code 1.43.2 (0ba0ca52957102ca3527cf479571617f0de6ed50, 2020-03-24T07:38:38.248Z)
OS version: Windows_NT x64 10.0.18362

Hello @mbtk,

Thank you for reaching out.

Can you send a screenshot of the error you're seeing? Can you also launch python in the terminal (Powershell or command prompt)?

Thanks!

[mbtk]

And yes, I launch python in the terminal and in VScode also everything works well. It's just an error and I don't know why VS keeps showing this error.

[kimadeline]

Where did you install Python from: Windows store, downloaded executable, built it yourself, another way? Where is it installed?

Can you try downgrading the extension to a previous version (2020.2.64397) and check if this error still appears?

As a workaround, you can try checking the Disable Installation Check box in your settings to silence that warning:

[mbtk]

I installed it from Windows store.
Anyway, I downgraded the extension to the version you mentioned and the error disappeared.
Thanks for your help.

[kimadeline]

Thank you for the feedback that downgrading works 👍 I won't close this issue, we will still need to investigate it further and fix it in the extension.

Telemetry: #10900

Downgrading to 2020.2.64397 doesn't work here, it still yells at me that I need to install Python. I have to manually set Python Path in vscode settings from python to C:\Users\Kagami\AppData\Local\Microsoft\WindowsApps\python.exe. PowerShell can access python so it shouldn't be PATH environment variable problem.

I'm on Windows 10 2004, BTW.

same as @saschanaz

[saschanaz]

I suspect this is an OS-wide regression as other tools e.g. MSYS shell can't access any store-distributed commands anymore because of a permission issue.

Please make sure that the extensions auto-update is disabled.

Please make sure that the extensions auto-update is disabled.

Auto-update is not fired and still:

When we switched to suing VS Code FS APIs looks like we started getting this issue. The files under %USERPROFILE%\AppData\Local\Microsoft\WindowsApps are apparently reparse points.

The underlying issue is we don't have a specific Windows Store App detection. Instead , we try to find the store app by searching it in directories listed in PATH env variable. Since, vscode.workspace.fs.readDirectory() does not get python.exe (reparse point) under %USERPROFILE%\AppData\Local\Microsoft\WindowsApps, we don't find it.

@kimadeline The reparse point might also be the reason for stat failing.

Filed microsoft/vscode#95828

FYI, on macos it fails to find /usr/local/Caskroom/miniconda/base/bin/python from conda too, same as #10900.

Part of the fix for this has to come from nodejs nodejs/node#33024 .
The temp workaround for this is in master. It will be available in the next release.

@holymonson @somas95 You might be running into a different issue. On mac and linux, usually the python that conda has is a symlink. I don't see a issue with node or VSC FS APIs with symlinks so far:

Can you try down grading extension version and see if it helps?

[stephtr]

For everyone stumbling across this issue: Even when using the next release version, there is an additional issue (#11412) with using Jupyter with the Microsoft Store version of Python. jupyter kernelspec list returns wrong (not sandboxed) paths (jupyter#544), which causes the vscode extension to not being able to start the kernel. A possible workaround is to create a new environment variable.

[somas95]

@karthiknadig It's not a conda install, rather a distro's repo one. I'll try downgrading the extension. Thanks!

I installed Python using chocolatey (choco install python) and am seeing the same issue: "python is not installed. please download..."

Fix for the windows store python is in build 2020.4.76186

[karthiknadig]

@sebastus give 2020.4.76186 build a try. If that does not work please file a separate issue.
