TL;DR

Set the GITHUB_PERSONAL_ACCESS_TOKEN environment variable and ensure pyright-langserver is installed and in the system's PATH.

Guidance

• The errors indicate a missing GITHUB_PERSONAL_ACCESS_TOKEN environment variable, which is required for the GitHub plugin to function correctly. Set this variable with a valid token.
• The pyright-langserver executable is not found in the system's PATH. Install pyright using a package manager like npm or yarn, and ensure the executable is added to the system's PATH.
• Verify that the environment variables are set correctly and the pyright-langserver executable is accessible by checking the system's PATH and environment variables.
• If using a package manager, try reinstalling pyright to ensure the latest version is installed and the executable is properly linked.

Example

No code snippet is provided as the issue is related to environment variables and executable paths.

Notes

The provided error messages are truncated, so there might be additional issues not addressed here. Ensure to review the full error log for any other potential problems.

Recommendation

Apply the workaround by setting the GITHUB_PERSONAL_ACCESS_TOKEN environment variable and installing pyright-langserver to fix the immediate issues. This should resolve the errors related to the missing token and executable.
