问题描述
我正在尝试在 python 2.7.18 上安装 networkx：
pip2 install networkx
我收到以下错误：
Running setup.py install for networkx ... error
ERROR: Command errored out with exit status 1:

我该怎么办？
解决方法
这意味着您没有足够的权限。
您可以使用 sudo 运行命令（如果您是 root 用户）：
sudo pip2 install networkx
或者只为当前用户安装
pip2 install networkx --user
PS：考虑升级到 pip3。
