Python 在MacOs上安装熊猫。权限错误

我正在尝试在mac上安装pandas。我已经安装了python 3.6

在终端中进行pip安装时，出现以下错误：

Exception:

您是否可以通过高亮显示错误并按ctrl+k将其编辑为格式化代码块，以便更易于阅读？谢谢

编辑：还有，我只是浏览了一下，底部写着拒绝许可。尝试以管理员身份重新运行该命令。即尝试以下命令：

sudo pip install pandas

您可能已经注意到，Mac附带了一个内置Python，即Python 2.7。如果您阅读回溯：

/Library/Python/2.7/site packages/pip-9.0.1-py2.7.egg/pip/basecommand.py

它指向2.7目录。此目录位于库文件夹中，因此您没有安装该目录的权限

---

但是您声明也安装了Python3.6，所以如果您想安装到该indtead。执行

pip3安装pandas

或

python3-m pip安装pandas

这有助于指定python版本。如果您想在终端上运行python 3.6，请键入

python3

，而不仅仅是

python

，很抱歉，这个问题在过去一周内至少被问了3次，请在发布之前尝试谷歌搜索。
