The system I am currently using has Anaconda pre-installed by root under system locations.
To install user packages, we need to install them to a user location. For
example, to install pylint, we need to add --user
option for pip install
:
pip install --user pylint
However, when I use pylint
command, I get the following error:
-bash: pylint command not found
Since there is no error when installing pylint, I think there is no problem
with installation. I use the find
command and find that pylint executable is
placed under ~/.local/bin
, which is not part of the PATH variable.
So the reason is that pylint
executable is installed into a directory that
isn’t in your PATH.
A more reliable way to find where the pylint executable is installed is to list
the files which are installed in pylint with the pip show
command:
pip show -f pylint
You will see part of the output like the following:
Location: /home/xxxx/.local/lib/python3.6/site-packages
Requires: astroid, mccabe, isort
Required-by:
Files:
../../../bin/epylint
../../../bin/pylint
../../../bin/pyreverse
../../../bin/symilar
So the location of pylint executable is $HOME/.local/bin/
. You should add the
directory to system PATH to use pylint:
export PATH=$HOME/.local/bin:$PATH
For flake8, the same issue exists and the solution is the same, which I will not elaborate on.
