用pip在Mac上安装Pandas

Question

我试图安装Pandas有pip,但遇到了一个问题.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Python 2.7.10在"/ usr/bin/python"中链接pandas

当我这样做时pip install pandas,我收到以下错误消息:

Collecting pandas

谢谢你的帮助.

Answer 1

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.您还可以安装这只是为你的用户应该用这符合你的使用情况:pip install --user pandas.

或者
