'Having trouble installing matplotlib in python

I tried updating conda, and I got this message: ERROR conda.core.link:_execute_actions(337): An error occurred while uninstalling package 'defaults::requests-2.14.2-py36_0'. PermissionError(13, 'Permission denied'). And if I try updating just matplotlib on conda, I get: ERROR conda.core.link:_execute_actions: An error occurred while installing package

The first question when you update conda is that PermissionError, maybe you just do not have enough system permission. The second question, you did not give enough error tips.
