Virtual Environment are used If you already have a python version installed and you want to use a different version for a project without bothering the older ones. it is good practice to use a new virtual environment for different projects.
There are multiple ways of creating that, today we will create one using mkvirtualenv command.
To use the mkvirtualenv command you need to have virtualenvwrapper installed which is nothing but a set of python extension commands.
Make sure you have pip installed.
$ sudo apt-get install python3-pip
$ sudo pip3 install virtualenvwrapper
Open bashrc by –
$ sudo gedit ~/.bashrc
After opening it, add the following lines to it :
export WORKON_HOME=$HOME/.virtualenvs export PROJECT_HOME=$HOME/Devel source /usr/local/bin/virtualenvwrapper.sh
Save the bashrc file.
Using mkvirtualenv command
Now let us use it,
The syntax is :
$ mkvirtualenv venv_name
If you want to work on another version of python, try this :
$ mkvirtualenv -p python3.x venv_name $(venv_name) // You will see something like this
Note: You can use any version in place of x.
To work on an existing virtual environment,
$ workon venv_name
To get out of the virtual environment –
