mkvirtualenv与virtualenv

Posted 2021-08-31 Jason_WangYing

好长时间没有创建新项目，虚拟环境还记得，但是今天在创建时我用了virtualenv来创建，创建后用workon发现没有东西，找了下文档，才发现用mkvirtualenv来创建才会在workon中有记录，并且创建成功后会自动进入虚拟环境。

jason-macbook-pro:django-wechat-example-master wangying$ mkvirtualenv testvir
created virtual environment CPython3.7.6.final.0-64 in 749ms
  creator CPython3Posix(dest=/Users/wangying/.virtualenvs/testvir, clear=False, global=False)
  seeder FromAppData(download=False, pip=bundle, setuptools=bundle, wheel=bundle, via=copy, app_data_dir=/Users/wangying/Library/Application Support/virtualenv)
    added seed packages: pip==20.1.1, setuptools==49.1.0, wheel==0.34.2

workjob
(testvir) jason-macbook-pro:django-wechat-example-master wangying$ deactivate
jason-macbook-pro:django-wechat-example-master wangying$ rmvirtualenv testvir
Removing testvir...
jason-macbook-pro:django-wechat-example-master wangying$ 

这是直接用virtualenv来安装虚拟环境，没有加入管理，这种的话需要直接进入对应的文件，在文件的/bin/里面有activate文件，运行：source activate，进入对应的虚拟环境。

jason-macbook-pro:demo wangying$ virtualenv testWechat
created virtual environment CPython3.7.6.final.0-64 in 926ms

  seeder FromAppData(download=False, pip=bundle, setuptools=bundle, wheel=bundle, via=copy, app_data_dir=/Users/wangying/Library/Application Support/virtualenv)
    added seed packages: pip==20.1.1, setuptools==49.1.0, wheel==0.34.2
  activators BashActivator,CShellActivator,FishActivator,PowerShellActivator,PythonActivator,XonshActivator
jason-macbook-pro:demo wangying$ workon testWechat
ERROR: Environment 'testWechat' does not exist. Create it with 'mkvirtualenv testWechat'.
jason-macbook-pro:demo wangying$ workon
backenev
firstEvn
workjob

最后附上虚拟环境操作的命令

安装虚拟环境的命令如下:
  sudo pip install virtualenv
  sudo pip install virtualenvwrapper

创建虚拟环境的命令如下：
  mkvirtualenv 虚拟环境名称
  例：
  mkvirtualenv hj_django

退出虚拟环境的命令如下：
  deactivate

查看与使用:
  workon 两次table

删除虚拟环境的命令如下:
  rmvirtualenv 虚拟环境名称
  例：
  先退出：deactivate
  再删除：rmvirtualenv py_django

包安装：
  pip install 包名（需要的环境包）
