I can't change permissions

Question

So my "code ." command doesn't work. I get the error

/usr/local/bin/code2: line 6: python: command not found
/usr/local/bin/code2: line 10: ./MacOS/Electron: No such file or directory

I saw that I just have to change python to python3 in the code file in /usr/local/bin. Except when I change the file, I'm unable to save it with the change. I get all sorts of errors telling me I don't have permission to change it. So then I look up how to change it, and it says to click on get info on the file, and then change the permissions in the sharing and permissions section. But my get info doesn't HAVE a sharing and permissions section!

What do I do?

PS: I realized I can see permissions if I do get info on the whole bin directory. I made it so everyone can read & write. Except I still can't save the altered version of the code file. I still don't know what to do anymore.

Answer 1

Ok I still have no idea how to save an edited version of the code file, but here is how I got around it for now.

brew install python
ln -s /usr/local/bin/python3 /usr/local/bin/python

Now I can use code . but I'm still very upset with my computer for not cooperating with me. ?
