pip更新超时失败之解法

python卡在pip安装包上了，我用的是pycharm，在它的交互命令行里使用

python -m pip install --upgrade pip

始终报错！
Traceback (most recent call last):
  File "d:\soft\python3.7\lib\site-packages\pip\_vendor\urllib3\response.py", line 331, in _error_catcher
    yield

    return self.read(nbytes, buffer)
  File "d:\soft\python3.7\lib\ssl.py", line 911, in read
    return self._sslobj.read(len, buffer)
socket.timeout: The read operation timed out

从错误上分析显然是下载超时了，那么怎么解决呢？肯定去找国内的镜像资源啊！于是我网上搜索了一番，终于找到了一个好用的：

python -m pip install --upgrade pip -i https://pypi.douban.com/simple
