pip安装库老是安不上，一直有错，line 425，in _error_catcher

ERROR: Exception:
Traceback (most recent call last):
File "c:xx \appdata\local\programs\python\python37\lib\site-packages\pip\_vendor\urllib3\response.py", line 425, in _error_catcher
   yield
...
...
...

解决办法
pip install 所要安装的库 -i http://pypi.douban.com/simple --trusted-host pypi.douban.com

pip 更新也不行，原来按提示python -m pip install --upgrade pip 更新出错

python -m pip install -U --force-reinstall pip
