错误:无法创建'/Library/Python/2.7/site-packages/xlrd':权限被拒绝

Question

我正在尝试在mac 10.8.4上安装xlrd,以便能够通过python读取excel文件.

我已按照http://www.simplistix.co.uk/presentations/python-excel.pdf上的说明进行操作

我这样做了:

1. 将文件夹解压缩到桌面

2. 在终端,cd到解压缩的文件夹

3. $ python setup.py安装

这就是我得到的:

为什么拒绝许可？谢谢

Answer 1

尝试 python setup.py install --user

您不应该sudo按照以上建议使用,原因有两个:

1. 您允许从因特网上运行任意不受信任的代码
2. 传递--user标志python setup.py install将包安装到用户拥有的目录.您的普通非root用户将无法访问由sudo pip或安装的文件sudo python setup.py

Answer 2

尝试 sudo python setup.py install

/ Library文件夹需要访问root权限.
