virtualenv: command not found in Python

Question

I am trying to create a new virtual environment for a tutorial. I have installed virtualenv and virtualenvwrapper multiple times but every time I try creating a new virtual environment my terminal displays - mkvirtualenv: command not found. When I try finding out the version of virtualenv it shows virtualenv: command not found. Something similar was happening with my pip installation as well but then it got resolved when I used some command.

I would like to point out that my PATH seems to be really messed up. The PATH is pointing to /Library/Frameworks/Python.framework/Versions/3.8/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Library/Apple/usr/bin. Please help.

I saw something else when I use pip show virtualenv it gives me details of the version and the author but when I use virtualenv --version it sends a virtualenv: command not found.

Answer 1

First of all, you will need to install virtualenv as it is a python 2 external dependency.

pip install virtualenv

this will allow you to use virtualenv globally.

Alternatively, you can use from Python 3.5+

python -m virtualenv venv

However if you dont wish to support python 2 you can use venv which is installed on from python 3.3

python3 -v venv venv

Answer 2

Took quite some time to figure it out but what worked for me was to install it using pip3 install instead of pip install

pip3 install virtualenv
