AngularJS Question

Unable to deploy a Nodejs application to Heroku (bower not found)

I've looked through similar stackoverflow questions and none of them seem to work for me. I've been trying to deploy my NodeJS app to Heroku but keep bumping into this message from heroku regarding bower. I have tried manually writing bower in my dependencies but that has not worked, I also tried moving my dependencies from bower.json to package.json but that also didn't work. Thank you guy so much, I have put my heroku logs, package.json, and bower.json files below.

angular-seed@0.0.0 postinstall /tmp/build_370f51a52877a36d300c739f31855511
remote: > bower install

remote: sh: 1: bower: not found

I have listed below my package.json and my bower.json files.

Answer Source

Try this instead for the postinstall:

"postinstall": "./node_modules/bower/bin/bower install"

This is because bower is installed locally in the specified path, not globally.
