A Virtual Environment is a python environment, that is an isolated working copy of Python which allows you to work on a specific project without affecting other projects
So basically it is a tool that enables multiple side-by-side installations of Python, one for each project.
Creating virtual environment in Linux
If pip is not in your system
$ sudo apt-get install python-pip
Then install virtualenv
$ pip install virtualenv
Now check your installation
$ virtualenv --version
Create a virtual environment now,
$ virtualenv virtualenv_name
After this command, a folder named virtualenv_name will be created. You can name anything to it. If you want to create a virtualenv for specific python version, type
$ virtualenv -p /usr/bin/python3 virtualenv_name
$ virtualenv -p /usr/bin/python2.7 virtualenv_name
Now at last we just need to activate it, using command
$ source virtualenv_name/bin/activate
Now you are in a Python virtual environment
You can deactivate using
Creating Python virtualenv in Windows
If python is installed in your system, then pip comes in handy.
So simple steps are:
1) Install virtualenv using
> pip install virtualenv
2)Now in which ever directory you are, this line below will create a virtualenv there
> virtualenv myenv
And here also you can name it anything.
3) Now if you are same directory then type,
You can explicitly specify your path too.
Similarly like Linux you can deactivate it like
