Terminal (zsh) command not found for global npm installs

Question

This is driving me nuts! I did a lot of googling and tried various things. (I do not consider this to be a superuser topic)

I'm having a lot of troubles with terminal lately. I must have messed up somewhere, because it used to work just fine and now I can't get it to recognize my commands anymore neither nvm or global npm packages like expo. It just gives me errors like this:

▶ expo      
zsh: command not found: expo

▶ nvm ls
zsh: command not found: nvm

(BTW: npm, brew and j commands are found 🤔)

If I do echo $PATH I get:

/Users/norfeldt/Library/Android/sdk/tools/bin:/Users/norfeldt/Library/Android/sdk/tools:/Users/norfeldt/Library/Android/sdk/platform-tools:/Applications/anaconda/bin:~/Library/Python/2.7/bin:~/.npm-global/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin

(strange behavior is that if I do echo $PATH again it returns two times the same output in one line)

A readable version of it (replacing : with :\n

/Users/norfeldt/Library/Android/sdk/tools/bin:
/Users/norfeldt/Library/Android/sdk/tools:
/Users/norfeldt/Library/Android/sdk/platform-tools:
/Applications/anaconda/bin:
~/Library/Python/2.7/bin:
~/.npm-global/bin:
/usr/local/bin:
/usr/bin:
/bin:
/usr/sbin:
/sbin

My .zshrc file looks like this:

# Node & NPM
#PATH="/usr/local/bin:$PATH"
PATH="~/.npm-global/bin:$PATH"
#PATH="~/.npm-global/lib/node_modules:$PATH"

# Git

export PATH

ANY help would be HIGHLY appreciated!

UPDATE

Reading the kind answer from @l'L'l and this answer I did the following:

Updated my .bash_profile to

export NVM_DIR=~/.nvm
source ~/.nvm/nvm.sh

(it's the only thing in that file)

created a .bashrc by $touch .bashrc (Might have deleted the old one.. But this is just an empty file..)

Added the following lines to .zshrc

PATH="$PATH:$HOME/.npm-global/bin/"             # Changed ~ to $HOME
PATH="$PATH:$HOME/.npm-global/lib/node_modules" # Changed ~ to $HOME
...
# Bash stuff
source ~/.bashrc
source ~/.bash_profile

Did a source ~/.zshrc and restarted my terminal.

NOW the nvm AND expo works! THANKS

There are a few things you might try, the first would be to source ~/.bash_profile from your .zshrc file. It's possible the nvm command was setup there and your zsh shell simply doesn't know it exists.

_{Note: On OS X, if you get nvm: command not found after running the install script, one of the following might be the reason:-}

_{your system may not have a .bash_profile file where the command is set up. Simply create one with touch ~/.bash_profile and run the install script again you might need to restart your terminal instance. Try opening a new tab/window in your terminal and retry. If the above doesn't fix the problem, open your .bash_profile and add
the following line of code:}

_{source ~/.bashrc}

_{For more information about this issue and possible workarounds, please refer here}

↑ Since you are using zsh instead at source ~/.bash_profile & ~/.bashrc in .zshrc.

If you used homebrew to install, then you might want to add the following into .zshrc:

export/source nvm installed with homebrew:

# source nvm
export NVM_DIR=~/.nvm

if hash brew 2>/dev/null; then
    source $(brew --prefix nvm)/nvm.sh
    source `brew --prefix`/etc/profile.d/z.sh
fi

npm not installed via homebrew:

export NVM_DIR="~/.nvm"
source ~/.nvm/nvm.sh
[[ -s "$NVM_DIR/nvm.sh" ]] && \. "$NVM_DIR/nvm.sh" # load nvm               
[[ -s "$NVM_DIR/bash_completion" ]] && \. "$NVM_DIR/bash_completion" # load nvm bash_completion
