angular-cli: "ERROR in Error: No NgModule metadata found for 'AppModule'." After Angular 5.2.1 and CLI 1.6.5 update

Unbelievable! It works after just editing any “.ts” file.

Update typescript of project to 2.6.2 solved it for me.

npm install --save-dev typescript@2.6.2.

Took sooooo much time to figure out as the solution of deleting cli and cache and reinstalling them was working only partially.

steps: cd to project directory

sudo npm uninstall -g @angular/cli
sudo npm cache verify
sudo npm install -g @angular/cli@latest
rm -rf node_modules dist
npm install --save-dev @angular/cli@latest
npm install

sudo npm update -D && sudo npm update -S
sudo npm install typescript@'>=2.4.2 <2.7.0'

I have the same issue when i update angular 2.x -> 6.x . I delete the package-lock.json and reinstall node_modules, it work fine now

Same problem as @Albejr tks for the temp workaround

This thinks make my job a special job, it’s pretty like y car not start for a engine problem and y open and close the door and the car start work again. LOL

I had a similar problem, but my problem was the name of the module when I was trying to load the module with lazy load. The first letter was in lowercase.

path/to/projects.module#projectsModule

so I changed it like this and it works: path/to/projects.module#ProjectsModule

Got the same error, in my case it is caused by an import statement: import NgModule = core.NgModule;

For instance following code report error when build.

import core = require("@angular/core"); import NgModule = core.NgModule; @NgModule( {....}) export class AppModule {}

And the error is gone if rewrite the code like below: import core = require("@angular/core"); @core.NgModule( {....}) export class AppModule {}

What happens if you upgrade typescript to 2.6.0?

Unbelievable! It works after just editing any “.ts” file.

@Albejr thank you very much bro!

难以置信的！只需编辑任何“.ts”文件即可。

me too

@Albejr wth?? how i can llive now with this… helps me too! but its looks bad

@Albejr your solution worked for me as well.

Even programming languages works with horoscope magics!!!

For me, I had an APP_INITIALIZER function/factory where the function was not "export"ed. Once I exported the function, it started working again.

OMG i can’t believe @Albejr solution worked for me.

@vapits this solved my problem, excellent !
