You are using pip version 19.0.3, however version 19.3.1 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.

解决办法：

python版本低于3.6

pip install pycurl -i https://pypi.tuna.tsinghua.edu.cn/simple

python高于3.6

pip install wheel

再打开http://www.lfd.uci.edu/~gohlke/pythonlibs/#pycurl，下载对应的pycurl版本的whl文件。

pip install pycurl-7.43.0-cp36-cp36m-win_amd64.whl
