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

錯(cuò)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(chuàng)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(yùn)行這個(gè).py文件即可

之后再用pip install安裝指令下載速度會(huì)非常快

2.報(bào)錯(cuò)：UnicodeDecodeError: ‘a(chǎn)scii’ codec can’t decode byte 0xd3 in position 7: ordinal not in range(128)

報(bào)錯(cuò)原因：pip安裝Python包會(huì)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(gè)文件sitecustomize.py

import sys  sys.setdefaultencoding('gbk')

python會(huì)自動(dòng)運(yùn)行這個(gè)文件
