What's the recommended way of installing python packages on Arch? Searching for them on the AUR and installing them from there (or create a PKGBUILD
file to make a package yourself) or using pip
?
I started off by installing stuff from pacman and the AUR and don't know if it would be wise to mix with pip
packages.

If you don't need the python packages for all users then you can install them in your home like this:
Installing in your home will not conflict with the package manager.
By default
pip install --user
will install in your "user site" directory. Usually that is something like:/home/lesmana/.local/lib/python3.6/site-packages
.The following command will print, among others, your "user site" location:
To customize the install location:
this will install everything under
$HOME/some/dir
to run:
See the pip manual for more information.
if you do want the python package for all users then the best place to install it is
/opt
. for example like this:(note the missing
--user
)and to run, as above:
Background explanation:
/opt
is commonly acknowledged by gnu/linux distributions as the directory where the local user or system administrator can install his own stuff. in other words: the package manager of distributions usually do not touch/opt
. this is more or less standardized in the Filesystem Hierarchy StandardFor comfort for the users you will still want to write a wrapper script and place it in
/bin
or/usr/bin
. This still bears risk of colliding with the distribution package manager but at least it is just one wrapper script file. So the damage that might be done is minimal. You can name the wrapper script something likelocal-foo
orcustom-foo
to further minimize the risk of collision with the distribution package manager.Alternatively you can modify
PATH
to include/opt/bin
and place your wrapper script there. But this again requires you to modify a (or some) system files wherePATH
is defined which again may be overwritten by the distribution package manager.In short: if you want to install for all users then do so in
/opt
. Where you place the wrapper script for comfort is a judgement call.More Information about
/opt
