Error: Cannot find module 'webpack'

[Hir0fumi]

It shows error while trying "5. Visualize". What could be the cause of this (issue/problem)? Appreciate your help. ("npm install;npm install -g webpack-dev-server"comand has NO ERROR)

npm start => localhost:8080 module.js:478 throw err; ^

@Hir0fumi can you share how you solved this issue?

[lefnire]

try npm install --global webpack or w/o --global

Thanks! It's working now, after I tried yarn add webpack-dev-server@^2.11.1
