When I try to install anything with pip or pip3, I get:
$ sudo pip3 install python3-tk
Tra
For CentOS I used this and it worked please use the following commands:
sudo pip uninstall requests
sudo pip uninstall urllib3
sudo yum remove python-urllib3
sudo yum remove python-requests
(confirm that all those libraries have been removed)
sudo yum install python-urllib3
sudo yum install python-requests
