Hi, I’m trying to build Anki from source but I keep running into this error: maturin failed Caused by: Expected `python` to be a python interpreter inside a virtualenv ಠ_ಠ The python interpreter specified in my path is inside a virtual environment I’ve created using venv. I’ve tried different envi…

I can’t seem to reproduce the issue with Cygwin and the latest master. Maybe try Git for Windows instead of Cygwin. C:\>uname -s MSYS_NT-10.0-19041 Evandro reported and fixed it in Makefile a while ago and I’m not sure why it’d appear again. ankitects/anki/blob/09a6a8078e1c6f2bde47f88fa3e…

I was mainly trying MinGW and cmd, I had also given Cygwin a shot. But what can I say… After reading your answer I tried Cygwin one more time and it worked! I must have done something else wrong when I last tried it. Still the same error message with other consoles, though. My bash skills are clo…

I’m getting this error too, on Ubuntu 20.04, as well after setting up a virtual environment with venv…

I’ve just been spending the last few hours on this, with no luck :frowning_face: I tried using venv with ‘env’, also with ‘pyenv’ as I see the scripts using. Now I tried with pyenv and I still get the same error (maturin failed Caused by: Expected python to be a python interpreter inside a virtuale…

I haven’t looked into this in super great detail, but here is my impression: because of the way that Anki’s build system bootstraps its own virtual environment, trying to build Anki with an activated virtual environment seems to be problematic. Activating a virtual environment before building Anki …

As I wrote above, the trick for me was to run make run -B in Cygwin. But that would also only work if I had deleted the pyenv folder before (after a failed build) or I would still get the error.

Thank you for your reply, Andrew. I tried that, too, but I don’t know how to get it to work, because Ubuntu doesn’t have an executable called python, only python3. I tried to create a function and export it: python() { python3 "$@" } export -f python That does work correctly, because if I type py…

And if I delete the pyenv folder it first downloads pip, and then setuptools, then pyqt5, then pyqtwebengine, then PyQt5-sip, and then fails with /bin/bash: maturin: command not found. If now I try to: source pyenv/bin/activate pip install maturin deactivate then it finally works! Gosh, that was …

[image] bubblekraft: So it seems that maturin isn’t correctly mentioned as a dependency? That isn’t the case, which you can verify by taking a look here and here [image] bubblekraft: Also, it sounds important to mention in the build instructions to not use a virtual env for pythong doing…

[image] andrewsanchez: [image] bubblekraft: Also, it sounds important to mention in the build instructions to not use a virtual env for pythong doing it I think that is a good point. Maybe you can submit a PR with those additions? I think a simple note mentioning that Anki configures the …

I’ve mentioned that a venv is not required in the docs on Changing Anki's build system to Bazel
