I'm trying to add python3 to my path by adding a symlink but it's erroring and I'm not sure why.
/usr/bin $ sudo su
sh-3.2# ln -s /Library/Frameworks/Python.framework/Versions/3.7/bin/python3 /usr/bin/python3
ln: /usr/bin/python3: Operation not permitted
sh-3.2# whoami
root
sh-3.2# ls -la | head -n 2
total 139064
drwxr-xr-x 977 root wheel 31264 24 Jul 2018 .
* Edit *
I have symlinked from /usr/local/bin/python3
so that's fine.

/usr/bin
is, as a lot of directories installed by default, protected by SIP and can't be modified by any user. There are ways to disable SIP, but the better approach is to use the directories beneath/usr/local
for user-installed thingsThe last line will make sure that
/usr/local/bin
is part ofPATH
for all shells started/Terminal tabs created after the line has been executed.
