在更改pyzmq版本时出现了一系列错误,具体如下:
pip install pyzmq ==19.0.2
Retrying (Retry(total=4, connect=None, read=None, redirect=None,
status=None))
pip install pyzmq==19.0.2-i http://pypi.douban.com/simple --trusted-host pypi.douban.com
pip install -i https://pypi.tuna.tsinghua.edu.cn/simple --trusted-host pypi.tuna.tsinghua.edu.cn pyzmq==19.0.2
pip install -i https://pypi.tuna.tsinghua.edu.cn/simple --trusted-host pypi.tuna.tsinghua.edu.cn --user pyzmq==19.0.2
安装pyzmq==19.0.2直接尝试
pip install -i https://pypi.tuna.tsinghua.edu.cn/simple --trusted-host pypi.tuna.tsinghua.edu.cn --user pyzmq==19.0.2
