I am trying to get started with elpy but any python file I open elpy will complain and say
eldoc error: (error Elpy necessitates the ’virtualenv’ python package, please install it with ‘pip install virtualenv‘)
Even if I am editing files in a directory with a virtualenv and I have $WORKON_HOME set to that directory.
(setq elpy-rpc-virtualenv-path 'current) works for me.
I followed this tutorial, and got the same error. When I looked at the buffer elpy-virtualenv, it showed the error that I have no module named virtualenv installed. It also showed me this:
Elpy failed to install its dedicated virtualenv due to the above
error. If the error details does not help you fixing it, You can
report this problem on Elpy repository on github.
In the meantime, setting the `elpy-rpc-virtualenv-path' option to
either `global' or `current' should temporarily fix the issue.
So I added the line (setq elpy-rpc-virtualenv-path 'current) in my ~/.emacs.d/init.el file. That solved the problem "temporarily" as it said. The permanent solution is to install virtualenv via package manager. For Ubuntu and other debian-based Linux distro, it is easy: sudo apt install virtualenv.
it's all in the sudo apt install virtualenv
