Stuck on "Reactivating terminals" - Failed to resolve env #23922

DrShushen · 2024-08-07T17:42:59Z

Type: Bug

Since the latest update of VSCode Insiders, the Python extension fails to launch (no syntax highlighting etc.), there is a permanent "Reactivating terminals..." in the status bar, and when I select OUTPUT > Python, I see the following error:

2024-08-07 18:35:35.873 [error] sendStartupTelemetry() failed. s [Error]: Failed to resolve env "/mnt/data-linux/miniconda3"
    at ae (/home/user/.vscode-insiders/extensions/ms-python.python-2024.12.2-linux-x64/out/client/extension.js:2:1968174)
    at oe (/home/user/.vscode-insiders/extensions/ms-python.python-2024.12.2-linux-x64/out/client/extension.js:2:1966134)
    at Immediate.<anonymous> (/home/user/.vscode-insiders/extensions/ms-python.python-2024.12.2-linux-x64/out/client/extension.js:2:1962428)
    at processImmediate (node:internal/timers:478:21) {
  code: -4,
  data: undefined
}

Not sure if it is related to the fact that my conda environments are on a mounted partition under /mnt/.

I have tried with Python pre-release and Release versions of the extension, and the issue happens in both cases.

The issue does not happen in vanilla VSCode (non Insiders)

More info for debugging this.

I have installed the exact same version of VSCode Insiders but with apt rather than snap, and this issue no longer happens.

Same problems. Except for the difference in the OS version, my VsCode insider version is the same.

Update:
After leaving it to run for a solid period of time (when I come back) the problem is mysteriously gone. I have no clue what is going on in the whatever backend this might involve but I do feel bad to somehow lose control of my workspace.

karthiknadig · 2024-08-16T17:46:35Z

A few things to try:
[Option 1] Try the command Python: Clear Cache and re-load from the command 🎨. I suspect there might be paths in cache that it is trying to find and somehow failing.
[Option 2] Try setting python.locator to native and reload. This will use a newer detector for python that should work faster. But, be sure to be on latest stable (2024.12.3 or greater) to get this.

corneliusroemer · 2024-08-17T17:47:12Z

Possibly same issue as this: #23963 (I encountered on macOS ARM)

Restarting my computer helped for me. My locator is already set to "native".

@karthiknadig did you maybe mean switch from native to js? The problem could be with native rather than js. At least per #23956 this helped some.

This issue occurs again and this time I tried the solution @corneliusroemer mentioned (switching native/js) and switching locator from native to js solved this issue for me after restarting vscode.

austinmw · 2024-08-19T02:09:17Z

I got the same error. Fresh install of VSCode (not insiders) on silicon mac. The above solution fixed it:

"python.locator": "js"

Not sure why this is broken, but not happy I wasted over an hour on this..

corneliusroemer · 2024-08-19T02:31:51Z

Thanks for sharing this worked for you @austinmw. I made a Stackoverflow question and answer in the hope more people quickly find the workaround until there's a proper fix: https://stackoverflow.com/questions/78886125/vscode-python-extension-stuck-on-reactivating-terminals/78886126#78886126

Update: wow the Q&A has already 135 views in just 11 hours - this suggests that a lot of people are getting this error. @karthiknadig would be great if someone at MSFT could look at this, I think. Hope the ping is ok in this case.

karthiknadig · 2024-08-22T18:30:46Z

There should be a mitigation pushed out in pre-release.

related: #23982

anthonykim1 · 2024-09-03T17:41:17Z

Are folks still suffering from this on the latest pre-release version? Just got another issue from #24026 so I want to make sure. Thought this was resolved based on:#23982 (comment)

corneliusroemer · 2024-09-03T22:39:32Z

@anthonykim1 I think it's impossible to say - report #24026 you linked to is insufficient to allow any conclusions - it's missing version of extension that's being used.

anthonykim1 · 2024-09-08T02:39:20Z

@corneliusroemer Great point -
Are folks using 2024.14.0 https://github.com/microsoft/vscode-python/releases/tag/v2024.14.0 or the latest pre-release of Python extension experiencing this 'reactivating terminals' problem?

nurpax · 2024-09-11T07:48:02Z

FWIW I just hit this with an updated VSCode (not insiders version):

Found the fix through the SO post, changing the "python.locator" to "js" helped.

corneliusroemer · 2024-09-11T08:30:20Z

@nurpax thanks for the report! What's your Python extension version?

nurpax · 2024-09-11T08:38:46Z

Looks like Python is at v2024.14.0. Pylance is v2024.9.1 in case that's relevant here.

corneliusroemer · 2024-09-11T15:52:15Z

@anthonykim1 something seems to have happened recently making this bug more frequent for folks - the views on my Stackoverflow question have shot up like crazy in the last day, I think from 600 to 900, and the question has been open for 23 days. So the view rate might be the highest it has ever been.

Adding a screenshot so we have a trackrecord:
