[Oldboy] [First knowledge of Django] Create a virtual (clean) Python environment [0]

What if application a requires Jinja 2.7 and application B needs Jinja 2.6? You can create different virtual environments for different applications at this time.

In this case, each app may need to have a "standalone" Python runtime environment. Virtualenv is a python run environment that is used to create a "quarantine" for an application.

1 PIP3 Install Virtualenv

2 virtualenv-p c:\python35\python3.exe--no-site-packages ENV35 (remember that the virtual Python environment you created at this time is not any third-party package ()

3 CD ENV35

4 Activating a virtual environment

　　./scripts/activate

5 You can install the third-party package you want to install at this time (for example, Django)

　　Pip Install Django

6 Exiting the virtual environment

　　deactivate


补充：在虚拟环境，使用django

　　cd d:\django_project
　　django-admin startproject mysite

CD MySite

Python manage.py runserver 127.0.0.1:8080
