Can you run dir on this directory to ensure that it has all the needed files?
c:\Users\admin.vscode\extensions\ms-python.isort-2023.10.1\bundled\tool\

Are you using any custom encoding in your OS?

[loskutov]

I am facing a similar issue. In my case, it's also about:

bundled/tool/lsp_server.py", line 39, in <module>
    import lsp_jsonrpc as jsonrpc
ModuleNotFoundError: No module named 'lsp_jsonrpc'

Indeed, bundled/tool is not in sys.path (update_sys_path() is only called with pathlib.Path(__file__).parent.parent / "libs")

See also https://github.com/microsoft/vscode-black-formatter/pull/286/files

[karthiknadig]

This seems to be the case for embedded/portable python. I am open for a PR adding the changes that were done for black to address this.

[Column01]

Also having this issue, the bundled install doesn't find the modules needed. Do not want to install them to my venv for the project either. I've gotten around this so far by installing it to another environment and then I pointed the extension to that one, but that's not ideal

[MiltiadisKoutsokeras]

I get this error:

2024-01-30 13:01:47.361 [info] Traceback (most recent call last):
  File "<HOME FOLDER HERE>/.vscode-oss/extensions/ms-python.isort-2023.10.1-universal/bundled/tool/lsp_server.py", line 41, in <module>
    import lsprotocol.types as lsp
ModuleNotFoundError: No module named 'lsprotocol'

I use Debian Linux 11, Python 3.9.2, isort v2023.10.1, VSCodium 1.85.2 (c8a36a69377856369f139f39ee56dd3838130fbf).

[MiltiadisKoutsokeras]

Is there any updates on this?

[karthiknadig]

@MiltiadisKoutsokeras If you are not using portable python then make sure the following directory exists in the extension.
<HOME>/.vscode-oss/extensions/ms-python.isort-2023.10.1-universal/bundled/lib. If it is not present then the OSS version of the extension build is broken.

[MiltiadisKoutsokeras]

I am coming back to this, indeed the directory <HOME>/.vscode-oss/extensions/ms-python.isort-2023.10.1-universal/bundled/lib is not present. The contents of a freshly installed plugin v2023.10.1 on VSCodium 1.88.0:

@MiltiadisKoutsokeras This issue is with how the package was created by whoever uploaded to the VSCodium's extension store. If you download the VSIX from the VS Code store you will see that it exists. Please raise an issue on the there. There is nothing we can do here.

[nriley]

I am having this problem with the official MS release of VSCode on Windows and the official VSCode store, not using VSCodium.

The problem as others have identified seems to be that the directory bundled\tool is not in the Python path.

I am using a portable Python as I am not an administrator on this computer and cannot install Python for the system. Here's what PYTHONPATH looks like prior to me doing this.

['c:\\Users\\nriley\\.vscode\\extensions\\ms-python.isort-2023.13.10681007\\bundled\\libs',
'',
'C:\\Users\\nriley\\Apps\\Python\\python311.zip',
'C:\\Users\\nriley\\Apps\\Python',
'C:\\Users\\nriley\\Apps\\Python\\Lib\\site-packages',
'C:\\Users\\nriley\\Apps\\Python\\Lib\\site-packages\\win32',
'C:\\Users\\nriley\\Apps\\Python\\Lib\\site-packages\\win32\\lib',
'C:\\Users\\nriley\\AppData\\Roaming\\Python\\venv\\3.11',
'C:\\Users\\nriley\\AppData\\Roaming\\Python\\venv\\3.11\\Lib\\site-packages']

Copying the following lines from the linked vscode-black commit and adding them to lsp_server.py fixed the issue:

BUNDLE_DIR = pathlib.Path(__file__).parent.parent
# Always use bundled server files.
update_sys_path(os.fspath(BUNDLE_DIR / "tool"), "useBundled")

Unfortunately I do not have time to submit a PR right now but did not want to get this lost, as I was somewhat confused reading this issue that the original reported problem is still a problem with a known solution and just awaiting a PR to fix.
