MEAN stack, Win 7, git push heroku master results in sh: bower: not found error

Question

Can some please advise why I'm getting this error when doing a git push heroku master on windows 7 for a basic mean stack app? I'm trying a basic mean stack app and did the following commands and finally "git push heroku master" command which resulted in the error - bower install
sh: bower: not found, npm ERR! weird error 127, npm ERR! not ok code 0, ! Failed to install --production dependencies with npm

cd mean-stack 
npm install
pm install -g bower
npm install -g yo grunt-cli [email protected]
bower install
git init
git add .
git status
git add -f public/lib
git commit -m "init"
heroku create
git push heroku master

 C:\ss\D1\google\04\mean\mean-stack>git push heroku master

Answer 1

You have bower listed in you devDependencies but not in your dependencies. devDependencies are only installed in the development environment.

-----> Installing dependencies with npm

So when Heroku runs npm install its running the production environment and is not installing the devDeps, including bower. Thats your issue!
