我尝试通过在终端中键入来使用 pip 安装 python 库 openpyxl:
pip install openpyxl
但是没有正确执行。它抛出了一个异常:
Successfully built openpyxl jdcal et-xmlfile

Exception:

请您参考如下方法:
最好的方法可能是使用 pip install <libname> --user
在你的情况下使用 pip install openpyxel --user 的意思
这会为您的用户安装软件包并且是安全的。您也可能有权为用户安装软件包。
您遇到的权限错误是一个常见的问题。可以在这里看到: pip is not able to install packages correctly: Permission denied error 在这里 error: could not create '/usr/local/lib/python2.7/dist-packages/virtualenv_support': Permission denied
使用 sudo pip 命令并不像这里解释的那样安全:What are the risks of running 'sudo pip'?
