[note] 安裝 windows 的 pip error

客戶端用 windows 2003 server

下載了 active python ，也安裝了 pip ，與一些 windows 下需要用安裝檔案的套件。

pip install -r requirements/我的相依套件檔案

立馬出現錯誤。

Exception:

於是只好先把 codign 的環境也裝一下，然後來看看是甚麼問題，拜了幾次大神終於下對了關鍵字，果然是與 Windows 的預設語系有關係，遙想 server 2003 的年代，算了，別想，改來就對了，找到 C:/Python27/lib/mimetypes.py 當中的

default_encoding = sys.getdefaultencoding()

把環境語系直接給定

if sys.getdefaultencoding() != 'big5':
    reload(sys)
    sys.setdefaultencoding('big5')
default_encoding = sys.getdefaultencoding()

接者繼續安裝套件囉！
