bash: create-react-app: command not found (pretty sure it's my $PATH)

Let me preface by stating that this is my first post, and also I can’t retrace my steps to where the create-react-app command no longer works in my Terminal. Last week, when I was practicing how to work with ReactJS I was able to use the command create-react-app and had been able to initialize a React project. However, I’ve been fiddling plentifully with NodeJS and NPM stuff simultaneously, and now when I call the create react-app command this is the output:

bash: create-react-app: command not found

I’m pretty sure it has to do with my $PATH, however I’m not experienced with making edits through vim when editing my .bash_profile. In my attempts to diagnose and fix the problem, here is what I appended to my $PATH through vim:

export PATH="/usr/local/bin:$PATH"

Nevertheless, I know the order of $PATH matters, but I’m naive as to whether I should prepend or append the $PATH above?

Here is what is output when I echo $PATH:

/usr/local/heroku/bin:/usr/local/bin:/usr/local/sbin:~/bin:/Users/bjornjohnramos/.rbenv/bin:/Users/bjornjohnramos/.rbenv/shims:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Users/bjornjohnramos/.npm-packages/bin/express -> /Users/bjornjohnramos/.npm-packages/lib/node_modules/express-generator/bin/express-cli.js:/Users/bjornjohnramos/.npm-packages/lib:export PATH="/usr/local/bin:$PATH":export PATH=$PATH:/Users/my_name/.npm-packages/bin/

my node and npm versions:

node v6.9.1 npm 4.2.0
