python - 安装 python 模块 IOError : [Errno 13] Permission denied:

Question

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
    Installing collected packages: jdcal, et-xmlfile, openpyxl
    Exception:
    Traceback (most recent call last):

    status = self.run(options, args)

    with open(dst, 'wb') as fdst:

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'?
