Problem

One of the most frequently asked type of question regarding this tool is how to make sure it and its plugins use or operate on the current project's venv, or else questions about issues caused by having failed to do so:

• Direct questions:
  • Am I supposed to always use python-lsp-server from a virtualenv? #603
  • Setting custom pythonpath in a per project settings file #177
  • system wide installation, multiple python versions #304
  • set the environment for the lsp server #496
  • How do I configure the python version that the code is written for? #398
  • [question] setting custom pythonpath in a per project settings file #162
  • Is it possible to select Python interpreter? #120
  • [Question] Virtual environments? #29
• Questions about issues caused by this:
  • Is auto-import supposed to work with 3rd party packages? #355
  • custom module path #77

Proposal

I suggest that there should be a section in the README or under thedocs/ folder on this topic which collects all the findings people have compiled so far (e.g.) and suggests some "best practices" for how to approach this topic.
