Messed up terminal after installing Angular [altered my zsh $PATH?] - macos

Question

I just installed Angular and after the default installation (as set out here: https://angular.io/guide/setup-local). After running the standard commands my terminal would not recognise ng (so I could not use ng new my-app).
To solve this problem I did the following based on a stackoverflow answer:
echo -e "export PATH=$(npm prefix -g)/bin:$PATH" >> ~/.bashrc
source ~/.bashrc
ng --version
(I had no knowledge of what PATH was when doing this, or what the command I was running did...)
This worked, and my ng --version returned a result and I was able to build and run an Angular app.
However when I opened a new tab in my terminal all my normal terminal 'styles' (I use zsh) had gone.
My friend and I tried to resolve the problem, which he felt might be related to my terminal settings (his 'Command (complete path)' read: /usr/local/bin/zsh, and mine was /bin/zsh). So we tried a few things but none have worked and it might be worse - this included resetting my $PATH based on another stackoverflow answer to /usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Library/Apple/usr/bin:/Library/Apple/bin.
We also switched back and forth from /bin/zsh to /bin/bash to try and resolve things, but this did not do anything.
The current state of things is that I cannot run rails commands where I normally could (for example), also things like ll (which returns zsh: command not found: ll).
This is my .zsh_history file:

This might be my old path? export PATH=/Users/joshua/.npm-global/bin:./bin:./node_modules/.bin:/Users/joshua/.rbenv/shims:/Users/joshua/.rbenv/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Library/Apple/usr/bin:/Library/Apple/bin:/usr/local/sbin
Anyway, you are a hero if you made it this far and if you have any idea what I should do I would be very grateful.

Answer 1

This was resolved by moving my dotfiles (which contains all my zsh settings) back to the original location. The change was caused by the re-ordering of many folders.
I also restored my PATH back to the old one pasted at the bottom of the question.
