Django：每次我开发 django 应用程序时都必须打开虚拟环境吗

Question

i have installed and set up the virtual environment using the command line. i am using pycharm to develop my django application. so that was day 1. On day 2 when i put my laptop back on to go back to working on my django application do i need to go back to command line and type in workon 'virtualenvironment-name' or can i just develop the django app without switching on the virtual environment.

Answer 1

First you need to have a clear idea what a virtual environment does.

The one and only thing virtual enviornment does is it isolates projects dependencies. You can definitely work without virtual environment. All you need to do is just install the libraries globally. That's it.

EDIT

Installing packages globally is not recomended because when you use virtual environment,

1. Managing project packages is easier
2. Resolving package version issues is much easier

Moreover, you should maintain a proper requirements.txt file when working with virtual environements because a single package might crash your entire code base. In that case you can totally delete the virtual environment and again start fresh.
