【Python】軟體管理工具--pip

    因為項目的原因我需要深入的學習python，後端程式依賴各種各種軟體包，比如MySQLdb，新手可能會有些不熟悉 如何快速安裝所需要的python 包。常用的python 包安裝和管理有 easy_install, setuptools, pip，distribute。

本文則介紹pip---“A tool for installing and managing Python packages.“

安裝pip

先要擷取腳本 get-pip.py  

wget https://bootstrap.pypa.io/get-pip.py

python get-pip.py

注意: 

get-pip.py 會幫你安裝setuptools,如果你已經安裝了，則會運作更新指令:

pip install -U setuptools

更新pip

pip install -U pip

安裝python 包

pip install SomePackage        # 不指定版本 則下載下傳最新版本

pip install SomePackage==1.0.4 # 下載下傳指定版本

例如 下載下傳安裝 MySQLdb

root@rac3:~/scripts# >pip install MySQL-python
