Virtualenv Command Not Found

Question

If you installed it with

pip install virtualenv

You need to run

sudo /usr/bin/easy_install virtualenv

which puts it in /usr/local/bin/.

The above directory by default should be in your PATH; otherwise, edit your .zshrc (or .bashrc) accordingly.

I faced the same issue and this is how I solved it:

1. The issue occurred to me because I installed virtualenv via pip as a regular user (not root). pip installed the packages into the directory ~/.local/lib/pythonX.X/site-packages
2. When I ran pip as root or with admin privileges (sudo), it installed packages in /usr/lib/pythonX.X/dist-packages. This path might be different for you.
3. virtualenv command gets recognized only in the second scenario
4. So, to solve the issue, do pip uninstall virtualenv and then reinstall it with sudo pip install virtualenv (or install as root)

The simplest answer. Just:

pip uninstall virtualenv

and then:

pip install virtualenv

Or you maybe installed virtualenv with sudo, in that case:

pip install --user virtualenv

On Ubuntu 18.04 LTS I also faced same error. Following command worked:

sudo apt-get install python-virtualenv

I had same problem on Mac OS X El Capitan.

When I installed virtualenv like that sudo pip3 install virtualenv I didn't have virtualenv under my command line.

I solved this problem by following those steps:

1. Uninstall previous installations.
2. Switch to super user account prior to virtualenv installation by calling sudo su
3. Install virtualenv by calling pip3 install virtualenv
4. Finally you should be able to access virtualenv from both user and super user account.

I had the same issue. I used the following steps to make it work

sudo pip uninstall virtualenv

sudo -H pip install virtualenv

That is it. It started working.

Usage of sudo -H----> sudo -H: set HOME variable to target user's home dir.

python3 -m virtualenv virtualenv_name   

or

python -m virtualenv virtualenv_name
