I've installed Heroku Toolbelt (https://toolbelt.heroku.com/) on a Windows 7 system.
I've followed the tutorial up to here: https://devcenter.heroku.com/articles/getting-started-with-nodejs#declare-app-dependencies
When I run the command npm install it gives the following error:
'npm' is not recognized as an internal or external command, operable program or batch file.
I understand this means it can't find/execute npm. But this is going from Heroku's own tutorial/documentation, in sequence, and doesn't say you need to install anything else to get this working. When I go to the npm website (https://www.npmjs.com/) it also says:
The npm command-line tool is bundled with Node.js. If you have it installed, then you already have npm too.
Something is wrong with this!
Try to reinstall nodejs. Alternatively, you can install nvm for windows, which is a version manager for nodejs. It's pretty useful and easy to install. Check it out at https://github.com/coreybutler/nvm-windows
