有人說:virtualenv、fabric 和 pip 是 pythoneer 的三大神器。html
無論認不認同,至少要先認識一下,pip如今卻是常常用到,virtualenv第一次據說,不過,總得嘗試一下吧。python
pip install virtualenv
由於我已經安裝了pip,那麼就直接用pip來安裝了,簡單方便。linux
其它的安裝方式請參考官方網站:http://www.virtualenv.org/en/latest/index.html測試
root@kali:/recall/code# virtualenv test_env New python executable in test_env/bin/python Installing setuptools, pip...done. root@kali:/recall/code#
很簡單,就是virtualenv 環境名稱[自定義的名稱,本身喜歡什麼就寫什麼]網站
默認狀況下,虛擬環境會依賴系統環境中的site packages,就是說系統中已經安裝好的第三方package也會安裝在虛擬環境中,code
若是不想依賴這些package,那麼能夠加上參數orm
--no-site-packages
創建虛擬環境htm
即變成了:教程
root@kali:/recall/code# virtualenv test_env --no-site-packages New python executable in test_env/bin/python Installing setuptools, pip...done. root@kali:/recall/code#
建立成功後,會在當前目錄下生成對應的目錄文件。ip
root@kali:/recall/code# ls -l test_env/ 總用量 16 drwxr-xr-x 2 root root 4096 4月 29 20:03 bin drwxr-xr-x 2 root root 4096 4月 29 19:58 include drwxr-xr-x 3 root root 4096 4月 29 19:58 lib drwxr-xr-x 2 root root 4096 4月 29 19:58 local root@kali:/recall/code#
咱們先進入到該目錄下:
cd test_env/
而後啓動
root@kali:/recall/code/test_env# source ./bin/activate
啓動成功後,會在前面多出 test_env 字樣,以下所示
(test_env)root@kali:/recall/code/test_env#
(test_env)root@kali:/recall/code/test_env# pip install requests Downloading/unpacking requests Downloading requests-2.2.1-py2.py3-none-any.whl (625kB): 625kB downloaded Installing collected packages: requests Successfully installed requests Cleaning up...

完整以下:
