解決方法：1、ReadTimeoutError，在pip安裝所在文件夾路徑下，創造python文件；2、UnicodeDecodeError，在Python27Libsite-packages下建個sitecustomize.py文件。

本教程操作環境：windows7系統、python3版、Dell G3電腦。

有時在用pip install命令安裝python庫時出現紅字報錯

1.報錯：ReadTimeoutError: HTTPSConnectionPool(host=’pypi.python.org’, port=443): Read timed out.

錯誤原因：連不上pip的源，下載依賴包失敗

解決(推薦)：在pip安裝所在文件夾路徑下，創造python文件(.py)

import os    ini="""[global]  index-url = https://pypi.doubanio.com/simple/  [install]  trusted-host=pypi.doubanio.com  """  pippath=os.environ["USERPROFILE"]+"\pip\"  if not os.path.exists(pippath):       os.mkdir(pippath)    with open(pippath+"pip.ini","w+") as f:       f.write(ini)

在cmd上運行這個.py文件即可

之后再用pip install安裝指令下載速度會非常快

2.報錯：UnicodeDecodeError: ‘ascii’ codec can’t decode byte 0xd3 in position 7: ordinal not in range(128)

報錯原因：pip安裝Python包會加載目錄包含中文字符，ascii不能編碼

解決：python目錄 Python27Libsite-packages 建一個文件sitecustomize.py

import sys  sys.setdefaultencoding('gbk')

python會自動運行這個文件
