zsh: command not found: on every package I install via npm | MAC OSX CATALINA

When I check versions on node and npm they both return fine and up to date. However, whenever I try to do anything with npm - compile sass, run tsc commands for typescript or work with React, I get this error: zsh: command not found: serve for example.

I believe it is an issue with my pathing, that I simply cannot sort out how to rectify, but I'm tired of getting these errors so I'm hoping I can find help here.

Here is my path when I run echo $PATH:

/usr/local/bin:/usr/local/sbin/:/usr/bin:/bin:/usr/sbin:/sbin:/usr/X11/bin

Here is my .zprofile:

# Setting PATH for Python 3.9
# The original version is saved in .zprofile.pysave
PATH=/usr/local/bin:/usr/local/sbin/:/usr/bin:/bin:/usr/sbin:/sbin:/usr/X11/bin
alias python="python3"

git_branch() {
  git branch 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/(\1)/'
}

export PS1="[\u@\h \W]\$(git_branch)\$ "

Here is my .zshrc file:

    # If you come from bash you might have to change your $PATH.
# export PATH=$HOME/bin:/usr/local/bin:$PATH

# Path to your oh-my-zsh installation.

I know these things are a mess, I was just learning a lot of this stuff when I was messing around a while ago, but now I need it for work. I'm grateful for any help in sorting out this mess!
