Desired behavior

App run normally

Mention any other details that might be useful (optional)

Application built and ran just fine before update.

Did try rm -rf node_modules and reinstall, no change.

I have faced same error. solved it: clean and reinstall global angular-cli and local angular.

@keyant

[keyant]

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'

Tried @keyant 's steps but still got the error No NgModule metadata found for 'AppModule'

I get this error seemingly random. Can't really see that I've changed anything and suddenly it just stops working and throws that error.

As an example: I had a branch in Visual Studio Team Services that built correctly, and when I re-queued the same build, without any changes, the build didn't work anymore...

What happens if you upgrade typescript to 2.6.0?

[wuzhen0808]

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 {}

Unbelievable! It works after just editing any ".ts" file.

Hi @jtsom and @Albejr,

Could you provide a project we can use to reproduce this? A github repo would be great.
