在MacO上安装熊猫。 权限错误

Question

I am trying to pip install pandas on a mac. I have python 3.6 installed.

When I pip install in the terminal I get the following error:

Exception:

Answer 1

Could you possibly edit the error into a formatted code block by highlighting it and pushing ctrl+k so it is easier to read? Thanks.

Edit: Also, I just looked through and at the bottom it says permission denied. Try rerunning the command as an admin. IE try this command:

sudo pip install pandas

You might have already noticed, Mac come with a built in Python, python 2.7. If you read your traceback: /Library/Python/2.7/site-packages/pip-9.0.1-py2.7.egg/pip/basecommand.py it's pointing to the 2.7 dir. this dir is in the Library folder so you don't have permission to install to it.

But you state that you have Python 3.6 installed as well, so if you wanted to install to that indtead. Do pip3 install pandas or python3 -m pip install pandas this help specify the python version. And if you want to run python 3.6 in terminal, type python3 instead of just python
