如题,有时候pip install的速度实在太慢,忍不了,这里记录解决方案。
以scipy的安装为例:
pip install scipy
贼慢,10k/s,要等半小时吧估计都不一定能下载。
pip install scipy -i https://pypi.tuna.tsinghua.edu.cn/simple
关键在于:-i https://pypi.tuna.tsinghua.edu.cn/simple
,使用的是国内源。
我在更新pip3的时候:运行pip3 install --upgrade pip
,报错如下:
apr@apr:~/test$ pip3 install --upgrade pip

You are using pip version 9.0.1, however version 20.1.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
由上可知,关键错误为:socket.timeout: The read operation timed out
原因在于:pip3下载速度太慢了。根本更新不了。(网络问题)
参考:socket.timeout: The read operation timed out 更改pip源至国内镜像,显著提升下载速度
网上有很多可用的源,例如
豆瓣:http://pypi.douban.com/simple/
清华:https://pypi.tuna.tsinghua.edu.cn/simple最近使用得比较多并且比较顺手的是清华大学的pip源,它是官网pypi的镜像,每隔5分钟同步一次,地址为
https://pypi.tuna.tsinghua.edu.cn/simple
运行:
pip3 install --upgrade pip -i https://pypi.tuna.tsinghua.edu.cn/simple
会发现超级超级快。
秒下。包括各种pip install指令。nice。
国内源还是给力的。
