本文介绍如何使用virtualenv创建一个名为'script'的Python3虚拟环境，并激活该环境。通过隔离Python环境，可以确保项目的依赖包版本正确无误。

You'll want to isolate the Python environment that your script is in by creating a virtual environment. This will allow you to install Python packages with the versions that the script expects.

Instructions

Create a Python 3 virtualenv called script.

Activate the script virtualenv.

/home/dq$ virtualenv -p /usr/bin/python3 script                                 

Running virtualenv with interpreter /usr/bin/python3                            

Using base prefix '/usr'                                                        

New python executable in /home/dq/script/bin/python3                            

Also creating executable in /home/dq/script/bin/python                          

Installing setuptools, pip, wheel...
