使用 pip 在 Mac 上安装 Pandas

我正在尝试安装Pandas with pip，但遇到了问题。详细信息如下：

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

我希望将 pandas 链接到Python 2.7.10在“/usr/bin/python”中

当我做pip install pandas，我收到以下错误消息：

Collecting pandas

谢谢你的帮助。

尝试以 sudo 身份运行 pip install 命令。

sudo pip install pandas

Python 包安装在操作系统文件系统中，并非所有用户都有权向其中写入文件。这就是为什么您需要以 sudo 身份运行命令，因为 sudo 会提升您执行此操作的权限。

编辑：这似乎得到了一些赞成票，所以我对这个有关用户特定安装的问题做了一些澄清。如果这适合您的用例，您也可以仅为您的用户安装它：pip install --user pandas.
