Python 安裝 SetupTools(easy_install, pip)

1. 首先到這裡(ez_setup.py)下載 ez_setup.py
2. 執行以下指令
#wget https://bitbucket.org/pypa/setuptools/raw/bootstrap/ez_setup.py -O - | python

如果你遇到
ERROR: cannot verify bitbucket.org's certificate, issued by `/C=US/O=DigiCert Inc/OU=www.digicert.com/CN=DigiCert High Assurance EV CA-1':
  Unable to locally verify the issuer's authority.
To connect to bitbucket.org insecurely, use `--no-check-certificate'.
Unable to establish SSL connection.

則表示你的系統不支援驗證 SSL, 請依指示加上參數--no-check-certificate



改成以下
#wget --no-check-certificate https://bitbucket.org/pypa/setuptools/raw/bootstrap/ez_setup.py -O - | python  

3. 下好了 ez_setup.py  後, 執行以下指令安裝
#python ez_setup.py install

不支援 SSL 的請用以下指令安裝,
#python ez_setup.py --insecure install

 以避免遇到以下的錯誤發生
