pipx install ignores packages installed by OS ?

[rumly111]

I installed a package that had lxml as it's dependency. In my OS (ubuntu) I had installed python3-lxml , and it was the version that satisfied the requirement of the package I wanted to install via pipx . But pipx still installed lxml in the program's venv, ignoring global python library lxml . Why did it happen, and how to prevent it?

"pipx install --system-site-packages" should be what you want. For more information, please refer to pipx install --help

I thought so as well, but --system-site-packages didn't help, maybe because python3-lxml installs into /usr/lib/python3/dist-packages

I did not test it, but what I know is that the --system-site-packages argument is passed directly to the venv module, so even if it is true, there does not seem to be anything pipx can do.
