Sudo pip3 command not found in raspberry pi 2 model B

I don't know at the moment either. I will come back to this question tonight.

Have you tried pip instead of pip3? It's usually in the same path, so if it doesn't work either, it's most likely a PATH issue..

echo $PATH What does it show you?

No reference to Python... You have to add the path to your local Python installation. The path is to be discovered by entering: which python in the terminal.

well yes, to check if the path was updated

please try to answer me!

yes I tried but still not working

/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/local/games:/usr/games

Thanks. I'm also confused

after which I should enter echo $path?
