我在用pip安裝一些第三方庫時，總會報錯，錯誤如下：
提示：
UnicodeDecodeError: 'ascii' codec can't decode byte 0xb1 inposition 34: ordinal
not in range(128)
ascii編碼不能解碼問題，查了好久，糾結了好久，終於找出問題所在了。。。。。。答案在下面!

原因是pip安裝Python包會載入我的使用者目錄，我的使用者目錄恰好是中文的，ascii不能編碼。
解決辦法是：
python目錄 Python27\Lib\site-packages 建一個檔案sitecustomize.py
內容寫：
import sys
sys.setdefaultencoding('gbk')
python會自動執行這個檔案。
