Mac-Mini:~ BBT$ pip3 --default -timeout=100 install -U pip3

 

Usage:   

  pip <command> [options]

 

ambiguous option: --default (--default-timeout, --default-vcs?)

Mac-Mini:~ BBT$ pip3 --default-timeout=100 install -U pip3

Collecting pip3

  Could not find a version that satisfies the requirement pip3 (from versions: )

No matching distribution found for pip3

Mac-Mini:~ BBT$ pip3 install -U --timeout 1000 matplotlib

 

    出现上述问题，主要是请求网络超时，这由于是国内的源的问题。所以解决这问题有两个方案：

    1.换源，这个我没有尝试过，但是网上的教程也是挺多的；

    2.设置pip3获取第三方库的请求超时时间。pip3 install -U --timeout 1000 matplotlib
