python – Trying to download a matplotlib module from cached data but it’s not working

original_terminal

So basically I don’t know how to use pyenv so i just download modules directly. This time I was trying to install matplotlib when I interrupted the process by CTRL-C since it was just showing the progress bar at full but doing nothing.
Then I tried to install again, with pip3 install matplotlib.py.
It ran the cached-matplotlib. Then this happened.
I’ve tried uninstalling it but it doesn’t exist, I’ve also tried restarting my laptop but it didn’t do anything.
I’ve searched online for the past 1 hour now and no answer at all.
If there’s really no way then I guess I’ll trying using pyenv(that’s what it’s for right?).
(I use pip3 because my default built-in python is python2)
Any help is appreciated.
