Step1:Use Python3 by virtualenv

reference ：https://packaging.python.org/guides/installing-using-pip-and-virtualenv/

Updata the python and pip at the latest version

python3 -m pip install --user --upgrade pip

python3 -m pip --version

Install the virtualenv

python3 -m pip install --user virtualenv

Note：If you are using Python 3.3 or newer the venv module is included in the Python standard library. This can also create and manage virtual environments, however, it only supports Python 3.

Creating a virtualenv

python3 -m virtualenv env

The second argument is the location to create the virtualenv. Generally, you can just create this in your project and call it env.

virtualenv will create a virtual Python installation in the env folder.

Activating a virtualenv

Before you can start installing or using packages in your virtualenv you’ll need to activate it. Activating a virtualenv will put the virtualenv-specific python and pip executables into your shell’s PATH.

source env/bin/activate

Leaving the virtualenv

If you want to switch projects or otherwise leave your virtualenv, simply run:

deactivate
