Angular 2 : No NgModule metadata found
I had this error even though I had everything that the answers above suggested in place. A simple edit in the app.module.ts file ( like delete a bracket and put it back) did the trick.
The problem is in your main.ts file.
const platform = platformBrowserDynamic();platform.bootstrapModule(App);You are trying to bootstrap App, which is not a real module.Delete these two lines and replace with the following line:
platformBrowserDynamic().bootstrapModule(AppModule);and it will fix your error.
Try to remove node_modulesrm -rf node_modules and package-lock.json rm -rf package-lock.json,after that run npm install.
