Uncaught Error: Cannot find module "./$$_gendir/app/app.module.ngfactory"

[manuelfink]

Compiling an app with angular-cli with

ng build --prod --env=prod --aot

I end up the the following error in the browser

Uncaught Error: Cannot find module "./$$_gendir/app/app.module.ngfactory"
    at Object.<anonymous> (main.925377c….bundle.js:31562)

    at window.webpackJsonp (bootstrap 6ea98d3…:23)
    at main.925377c….bundle.js:1

the code causing the error is:

/***/ },
/* 208 */
/***/ function(module, exports, __webpack_require__) {

"use strict";
/* harmony import */ var __WEBPACK_IMPORTED_MODULE_0__polyfills_ts__ = __webpack_require__(285);

throw new Error("Cannot find module \"./$$_gendir/app/app.module.ngfactory\"");
/* harmony import */ var __WEBPACK_IMPORTED_MODULE_4__angular_platform_browser__ = __webpack_require__(270);

Versions

MacOS 10.12.2
angular-cli: 1.0.0-beta.21
node: 6.9.1
os: darwin x64

Any idea what may be the origin of the error?

Can you share a repository showing a sample project with this error?

That is, create a new Angular CLI project, and then try to reproduce the error?

Thanks.

Having same issue here.

Uncaught Error: Cannot find module "./$$_gendir/app/app.module.ngfactory" at Object.<anonymous> (main.78a068d….bundle.js:21992) at r (bootstrap 3bff2fc…:52) at Object.<anonymous> (main.78a068d….bundle.js:34716) at r (bootstrap 3bff2fc…:52) at window.webpackJsonp (bootstrap 3bff2fc…:23) at main.78a068d….bundle.js:1

This is happening only when serving dist folder content generated with ng build --prod --env=prod --aot and directly on the log output after running ng build command. When skipping --aot parameter it returns no error.

I finally managed to resolve it by deleting every single test file in my application folder. I was working under the assumption that angular-cli would exclude these files by default but it seems it's not the case with my current setup (using angular-cli@1.0.0-beta.21).

Closing as there was no reproducion given by original author.

@annvnzndrvn you're using a pretty old version, I recommend updating.
