Use the following command to install virtualenv on your ubuntu system
sudo apt-get install python-virtualenv
When we create a virtual environment using the virtualenv command, the default python interpreter used is /usr/bin/python27 (and then a corresponding copy of that interpreter is created), so how do we specify the version of the interpreter?
Use the parameter -p
$ sudo virtualenv -p ~/anaconda3/bin/python test
The above method of specifying the version of python interpreter by virtualenv is all that I have shared with you.
