'Why does pip not show any installer for some packages?
pip list --verbose
^ shows a list of every package installed in my environment, but several packages show no installer, like so:
Package Version Location Installer
---------------------------------- -------------------- ------------------------------------------------------------------------ ---------
alabaster 0.7.12 /home/jaden/anaconda3/lib/python3.9/site-packages conda
anaconda-client 1.9.0 /home/jaden/anaconda3/lib/python3.9/site-packages conda
anaconda-navigator 2.1.1 /home/jaden/anaconda3/lib/python3.9/site-packages
anaconda-project 0.10.1 /home/jaden/anaconda3/lib/python3.9/site-packages conda
anyio 2.2.0 /home/jaden/anaconda3/lib/python3.9/site-packages conda
appdirs 1.4.4 /home/jaden/anaconda3/lib/python3.9/site-packages
argh 0.26.2 /home/jaden/anaconda3/lib/python3.9/site-packages
argon2-cffi 20.1.0 /home/jaden/anaconda3/lib/python3.9/site-packages conda
Why is that? How were they installed?
Solution 1:[1]
Pip gets this information from the corresponding .dist-info/INSTALLER of a package. The use of a .dist-info folder is specified by PEP 376. Prior to this, packages followed the specification in PEP 262, which does not include the INSTALLER information.
Not sure about what goes in to why particular packages still use the older specification, but those that lack the .dist-info will show up with blank "Installer" values. That is, the blank should be read as "undetermined" rather than "not from (conda/pip)". So, given only a pip list --verbose output, one cannot determine the origin for those.
Checking my own base, I see conda, pip, setuptools, and wheel all blank, though they are all Conda package installations for me. And this can be confirmed through conda list.
