Why "Refactor" feature doesn't work after installed Python extension in VS Code?

[Kai Yin (leonyk)]

I see Python extension for VS Code created by Microsoft is supporting refactoring function like Extract Variable, Extract Method and Rename Module etc.
However, it doesn't work for me. Even I installed "Python" extension, and selected the line of code you wish to extract as a variable, then click "Refactor..." from the right-click menu. It shows that "no refactorings available"...

Anyone who knows how to make it works? Appreciate any hint in advance.

I found the solution and fixed it by running "pip install pyslp-rope".

That would suggest you are using Jedi to do refactoring, which we don't directly control. But this is supported by Pylance which is our default editing experience.
