use Python Virtual Environment
# install
pip install virtualenv
# test your installation
virtualenv --version
# you can create a virtualenv using the following command
virtualenv my_name
# After running this command, a directory named my_name will be created. This is the directory which contains all the necessary executables to use the packages that a Python project would need. This is where Python packages will be installed. If you want to specify Python interpreter of your choice, for example Python 3, it can be done using the following command:
$ virtualenv -p /usr/bin/python3 virtualenv_name
# To create a Python 2.7 virtual environment, use the following command:
$ virtualenv -p /usr/bin/python2.7 virtualenv_name
# Note: source is a shell command designed for users running on Linux (or any Posix, but whatever, not Windows).
# To activate virtual environment using windows command prompt change directory to your virtual env
# windows
$ cd <envname>
$ scripts/activate
# linux/posix
$ source virtualenv_name/bin/activate
