Heroku error: Cannot find module webpack
This is more of a trouble shoot answer, but this issue generally arises with one of two issues:
- webpack is globally installed (at some point you did
npm install webpack -g) - webpack is installed as a devDependency.
If you are running a server that require's in webpack, you're going to install it as a dependency.
If you're not doing any serverside middleware, then setting webpack as a devDependency is generally what you want.
