Hi,

I installes Python 3.7 on my Raspberry Pi 3 Model B.
I used those sites:
https://gist.github.com/SeppPenner/6a5a3...524417761d
https://www.ramoonus.nl/2018/06/30/insta...pberry-pi/
https://installvirtual.com/install-pytho...pberry-pi/
https://forums.sickrage.ca/t/how-to-migr...hon-3/1365

Once installed I have many troubles using pip.

Here the error:

pi@RaspberryMadjo:~/Downloads/Python-3.7.0 $ python3 -m pip install --user --upgrade pip
Exception:

Coul someone help me to understand what's hapenning ?

Thanks.

Did you remove python2?
what output are you getting in terminal:
pip --version
pip3 --version
found solution :here

The lsb_release uses on Ubuntu Python 3. On Raspbian I guess Python 2.7.
If you change system wide the interpreter to python3 as symlink to python, you'll
run into many issues. Some OS-tools still require Python 2.7.
I guess with the next release of Raspbian they would change many tools to use Python 3 as standard.

I hope that 2020 this problem is defused.

A better approach is a user-instalation of Python. I use always pyenv on Rapsberry Pi, but compiling everything takes time.
