How to use Poetry with PyCharm? All imports show warning No module named....

[simon-liebehenschel]

• I have "pyproject.toml" and "poetry.lock" files.
• I have all packages installed via poetry install
• I can run my code that uses installed packages.

PyCharm 2021.3.1

Problem

When I import any package in PyCharm, I see No module named 'blablabla' .

Question

How to support packages imports, auto-completion?

How to view packages source code?

Workaround

I have to install all packages via "Pip" in parallel to hide PyCharm import warnings No module named 'blablabla' . This is super stupid.

Pycharm 2021.3 now offers Poetry support. Is that the version of Pycharm you are using?

[simon-liebehenschel]

I already wrote PyCharm version in my post. Read my post again. Yes, the version is "21.3.2".

[jacob-lee]

Apologies.

I recommend posting this to JetBrains issue tracker, if you haven't done so already.

Did you select the poetry environment as interpreter? After I did that, everything works as expected.

[simon-liebehenschel]

Of course I selected poetry environment as interpreter.

PyCharm is a full of bugs software, so probably it does not work well when a pip was used before Poetry for the same project.

Solution:

1. Uninstall Pycharm
2. Remove your project
3. Remove cache files

Install PyCharm again, add the project again, add an interpreter again.

Now imports are not red. Now I can autocomplete imports.

Hi, having similar issue.

• What do you mean by "Remove your project" given you've already uninstalled Pycharm at this point? e.g. delete all the files?
• "Remove cache files" - Pycharm's or Poetry's?

Thanks!

@elliot-100 Sadly, the solution above is not persistent. If you want to make PyCharm work well with Poetry, then I recommend to use virtualenvs.in-project = true to create venv within the root directory of the project. This way PyCharm config for a project will not disappear randomly on next PyCharm restart.

---

By the way, I migrated from PyCharm because it indexing (scanning) a whole .venv on every restart which is extremely slow... perhaps PyCharm developers do not know about caching. I will not write to what I switched to avoid someone thinking that I am advertising here another IDEs, but I highly recommend to give a try with a few other popular IDE if you work with Python.

Thanks, I'll try putting the virtualenvs in the project.

Yes, am also finding Pycharm frustrating at the moment. Am only working on small projects, so reindexing isn't too much of an issue. But its Poetry (and other environments) handling seems very unreliable.
