为虚拟环境新建一个目录。

创建一个目录将其命名为 virtualenv,再在终端中切换到这个目录,

先安装virtualenv

如有则跳过

pip install --user virtualenv

可以使用如下指定源:pip install virtualenv -i https://pypi.tuna.tsinghua.edu.cn/simple

在终端中切换到目录

切换到目录virtualenv

创建Django虚拟环境

并像下面这样创建一个虚拟环境:

D:Pythonworkvirtualenv>virtualenv django2.2.12_learn

created virtual environment CPython3.7.0.final.0-64 in 1015ms

creator CPython3Windows(dest=D:Pythonworkvirtualenvdjango2.2.12_learn, clear=False, no_vcs_ignore=False, global=False)

seeder FromAppData(download=False, pip=bundle, setuptools=bundle, wheel=bundle, via=copy, app_data_dir=C:UsersXiaoAppDataLocalpypavirtualenv)

added seed packages: pip==22.2.2, setuptools==65.3.0, wheel==0.37.1

activators BashActivator,BatchActivator,FishActivator,NushellActivator,PowerShellActivator,PythonActivator

D:Pythonworkvirtualenv>

生成目录如下:

激活虚拟环境

建立虚拟环境后,需要使用下面的命令激活它:

D:Pythonworkvirtualenv>django2.2.12_learnScriptsactivate

(django2.2.12_learn) D:Pythonworkvirtualenv>

虚拟环境中安装Django

==指定版本,-i指定源

(django2.2.12_learn) D:Pythonworkvirtualenv>pip install Django==2.2.12 -i https://pypi.tuna.tsinghua.edu.cn/simple

在依然处于活动的虚拟环境的情况下(django2.2.12_learn包含在括号内) , 执行如下命令来新建一个项目最后有个空格和.,可以自行测试带.和不带.的区别

创建程序

当前,在前面打开的终端窗口中应该还运行着runserver 。 请再打开一个终端窗口(或标签页) , 并切换到manage.py所在的目录。 激活该虚拟环境, 再执行命令startapp :
