App started using angular cli

The log given by the failure.

This is from my command line:

ERROR in Unexpected value 'null' declared by the module 'AppModule in C:/Users/T
haniri/Desktop/freecodecamp/myroute/src/app/app.module.ts'

ERROR in ./src/main.ts
Module not found: Error: Can't resolve './$$_gendir/app/app.module.ngfactory' in
'C:\Users\Thaniri\Desktop\freecodecamp\myroute\src'
@ ./src/main.ts 3:0-74
@ multi ./src/main.ts

Mention any other details that might be useful.

ng serve works fine, its just ng build -prod

Here are the contents of my main.ts file:
`import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { enableProdMode } from '@angular/core';
import { environment } from './environments/environment';
import { AppModule } from './app/app.module';

if (environment.production) {
enableProdMode();
}

platformBrowserDynamic().bootstrapModule(AppModule);
`

If there is more information needed, please let me know. I am trying to learn how to deploy my Angular website.

Having the same failure on both linux and windows platforms.

This may or may not be helpful but I have noticed that the first error seems to be the primary cause and the Module not found error is generic and will happen any time something breaks the aot build.

In my case I was getting the following any time I had an empty scss file:

ERROR in Child compilation failed:
Module build failed: No input specified: provide a file name or a source string to process:
[object Object]

ERROR in ./src/main.ts
Module not found: Error: Can't resolve './$$_gendir/app/app.module.ngfactory' in '/Users/mhamel/Development/blispay/blispay-ui2/src'
 @ ./src/main.ts 4:0-76
 @ multi ./src/main.ts

As soon as I fixed the first error, the Module not found error resolved itself. From that, I would expect @IlyaSurmay and @agarbutt each have different project specific bugs. (Possibly aot compiler related)

Can you see if the --verbose flag gives you any more information about the error?

CTRL+F the document for 'was generated' to find out what command I used:
ng build -prod --verbose > aFile.txt
ng build -prod --verbose

If you want to try it yourself please clone this repo:
https://github.com/thaniri/angularPortfolio

I have no empty .scss files, and even if I attempt to add something to styles.css in the src folder, I get the same error.

The same thing happens for me. No error other than:

ERROR in ./src/client.aot.ts Module not found: Error: Can't resolve './$$_gendir/browser.module.ngfactory' in '/home/pradej/Projekty/site-backoffice/src' @ ./src/client.aot.ts 2:0-75

I had to make a separate, plain client entry point for AOT, but it still doesn't work.

import { enableProdMode } from '@angular/core';
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';

import { MainModule } from './browser.module';

enableProdMode();

platformBrowserDynamic().bootstrapModule(MainModule);

OS: Fedora 25 x64

Also, if that's helpful, my project is using Universal, but AOT is used for client only.

I think it might be ngc. I cannot make it generate anything even when running it directly. 16.02.2017 4:43 PM "Ilya Surmay" <notifications@github.com> napisał(a):

Same error when I upgraded to 4.0.0-beta.8. Previous version 4.0.0-beta.7 doesn't have this failure.

[adessilly]

This is how I fixed my issues with the last version of angular-cli :
https://medium.com/@isaacplmann/making-your-angular-2-library-statically-analyzable-for-aot-e1c6f3ebedd5#.n4b11wso1

With the last version of angular-cli, ng build --prod seems to compile with --aot by default : I didn't know there was good practices to make project working with...

See next. I found a solution for me.

I hope this helps.

Similar problem with 1.0.0-rc1 on Windows. Running ng build --prod gives

ERROR in Error encountered resolving symbol values statically. Could not resolve events relative to C:/Projects/craft-ng/editor/node_modules/blocking-proxy/built/lib/webdriver_commands.d.ts., resolving

ng build --prod --aot=false executes without problems.
