安装python模块IOError:[Errno 13]权限被拒绝:

Question

我尝试通过键入终端使用pip安装python库openpyxl:

    pip install openpyxl

但它没有正确执行.它引发了一个例外:

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

    with open(dst, 'wb') as fdst:
    IOError: [Errno 13] Permission denied: '/Library/Python/2.7/site-packages/jdcal.py'

最好的方法是使用 pip install <libname> --user

在你的情况下使用意义 pip install openpyxel --user

这将为您的用户安装包,这是安全的.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问题.从这里可以看出: pip无法正确安装包:权限被拒绝错误 和此处错误:无法创建'/usr/local/lib/python2.7/dist-packages/virtualenv_support':权限被拒绝

使用sudo pip命令不被认为是安全的,如下所述:运行'sudo pip'有什么风险？
