Python2：安装networkx

如何解决Python2：安装networkx

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:
     command: /Library/Frameworks/Python.framework/Versions/2.7/Resources/Python.app/Contents/MacOS/Python -u -c 'import sys,setuptools,tokenize; sys.argv[0] = '"'"'/private/var/folders/1b/8lq89lxj07bd6rvtl1k6g1b80000gn/T/pip-install-xAglEZ/networkx/setup.py'"'"'; _file='"'"'/private/var/folders/1b/8lq89lxj07bd6rvtl1k6g1b80000gn/T/pip-install-xAglEZ/networkx/setup.py'"'"';f=getattr(tokenize,'"'"'open'"'"',open)(file);code=f.read().replace('"'"'\r\n'"'"','"'"'\n'"'"');f.close();exec(compile(code,__file_,'"'"'exec'"'"'))' install --record /private/var/folders/1b/8lq89lxj07bd6rvtl1k6g1b80000gn/T/pip-record-cJQmE6/install-record.txt --single-version-externally-managed --compile --install-headers /Library/Frameworks/Python.framework/Versions/2.7/include/python2.7/networkx
         cwd: /private/var/folders/1b/8lq89lxj07bd6rvtl1k6g1b80000gn/T/pip-install-xAglEZ/networkx/

最后：

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。
