Extra semicolon in path enviroment variables #740
Description
Hi,
this extension adds to the environment variables inside vscode extra ';' at the end of the system
%PATH% !!! This causes double semicolon in the env variable !!!
'<some paths here>;;c:\Users\<name>\.vscode\extensions\ms-python.debugpy-2025.8.0-win32-x64\bundled\scripts'
You can test it via disabling the plugin and print it vscode env variables.
Here is vscode task to simplify testing:
{
"label": "Set Environment Variables",
"type": "shell",
"command": "cmd.exe /c set > %TEMP%\\vscode_env.txt",
"problemMatcher": [],
"presentation": {
"panel": "shared",
"reveal": "always",
"focus": false,
"showReuseMessage": true,
"clear": false,
"echo": true,
}
}
This error caused me GNU MAKE (4.2.1) not to work and hangs for 30minutes. If anyone have same issue, upgrade to newer GNU Make, it works fine with GNU Make 4.3 Built for x86_64-pc-msys.
Fix it !

Here's the code for that append:
vscode-python-debugger/src/extension/noConfigDebugInit.ts
Lines 78 to 80 in 34d2833

This is interesting, I did a research on few PCs and a small group had ending without the semicolon. I couldn't find correlation (win11/win10, apps, anything...). Would it be worth it to update the code to check for ';'?

To clarify your path, at this point, ends with a semicolon before the addition is made?

Just to clarify that my previous post. That meant some of the paths on some of the PCs ends with semicolon. Yes my path also ends with semicolon.

The change then that needs to be made is checking to existing PATH variable, if it has a semicolon don't add another when you append. See code marker:
vscode-python-debugger/src/extension/noConfigDebugInit.ts
Lines 78 to 80 in 34d2833
