我试图用pip安装Pandas,但遇到了问题.以下是详细信息：

Mac OS Sierra
which python => /usr/bin/python
python --version => Python 2.7.10
Inside "/System/Library/Frameworks/Python.framework/Versions" there is the following
2.3 2.5 2.6 2.7 Current

我希望在“/usr/bin/python”中将pandas链接到Python 2.7.10

当我做pip安装pandas时,我收到以下错误消息：

谢谢你的帮助.

解决方法

尝试以sudo身份运行pip install命令.

sudo pip install pandas

Python软件包安装在操作系统文件系统中,并非所有用户都有权将文件写入.这就是为什么你需要以sudo运行命令的原因,因为sudo会提升你的权限来执行此操作.

编辑：这似乎得到一些upvotes所以我已经添加了一些关于用户特定安装的问题的清晰度.如果这符合您的用例,您也可以只为您的用户安装：pip install –user pandas.
