Errors

Common errors & fixes

ModuleNotFoundError: No module named 'jedi'

The 'jedi' package is not installed in the Python environment being used, or the Python environment where it is installed is not correctly configured in the IDE/editor.

fix

Ensure 'jedi' is installed in your active Python environment: `pip install jedi` or `python -m pip install jedi`.

AttributeError: module 'jedi' has no attribute 'Script'

This typically occurs when an outdated or incompatible version of 'jedi' is installed, or when there's a conflict in the Python environment leading to the wrong 'jedi' module being loaded. The `Script` class might have moved or been removed in a newer major version, or the installed `jedi` is too old for the code trying to use `Script`.

fix

Upgrade 'jedi' to the latest version: `pip install --upgrade jedi`. If the issue persists, ensure no conflicting 'jedi' installations exist and try reinstalling it: `pip uninstall jedi && pip install jedi`.

ImportError: cannot import name 'traverse_parents'

This error points to an internal inconsistency or version mismatch within the 'jedi' library or its dependencies, often due to a partial or corrupted installation, or an incompatibility with the Python version being used.

fix

Reinstall 'jedi' to ensure all its components are consistent: `pip uninstall jedi && pip install jedi`. If using a specific editor plugin (like jedi-vim), ensure it's compatible with your installed Python and jedi versions.

AttributeError: module 'typing' has no attribute '_SpecialForm'

This error often arises from a compatibility issue between the 'jedi' library (or its components like 'jedi-language-server') and the `typing` module, particularly with older Python versions or specific setups where `typing` might be backported or have an unexpected structure.

fix

Update `jedi` and any related language server components to their latest versions: `pip install --upgrade jedi jedi-language-server`. Consider ensuring your Python environment is up-to-date, especially if you are using an older Python 3.x version.
