Hi all,

I created an ionic project and cloned it elsewhere, when I run ionic serve, I get errors such as the following.

```
[21:29:17] rollup: Conflicting namespaces: /Users/pbrack/dev/paystumped/paystumped/node_modules/@angular/compiler/index.js
            re-exports 'PropertyBindingType' from both /Users/pbrack/dev/paystumped/paystumped/node_modules/@angular/compiler/src/template_parser/template_ast.js
            (will be ignored) and /Users/pbrack/dev/paystumped/paystumped/node_modules/@angular/compiler/src/template_parser/template_ast.js.

[21:29:23] bundle finished in 7.48 s

```

When I run ionic build ios I get the following error.

```
[21:39:42] /Users/pbrack/dev/paystumped/paystumped/node_modules/@angular/compiler-cli/src/private_import_compiler.js:10
[21:39:42] exports.AssetUrl = compiler_1. __compiler_private__.AssetUrl;

[21:39:42] ngc failed
[21:39:42] ionic-app-script task: "build"
[21:39:42] Error: Error

```

Has anyone else seen this? If so, how can I avoid the warnings.

Any chance you put the contents of `node_modules` under version control? I think that’s generally considered a bad idea.

I’m also getting the same thing, even with the same dependencies. Ran `rm -rf node_modules` and `npm cache clean` and a fresh `npm install` multiple times, but I get the same thing.

Same here ☹

```

on npm run build / ionic build  
I get a [14:22:10] TypeError: Cannot read property ‘AssetUrl’ of undefined

ionic serve works fine, only throws the conflicting namespaces warnings at rollup

THIS fixed it for me :

Pin down the versions, remove all caret signs (^) before version numbers, if you have any .

This also worked for me and I deleted node\_modules first just to be safe.

I too got the same AssetUrl error. I removed the caret sign. When I run ionic build, I am getting following error

Seeing same problems, many of them. So far for no breaking changes in RC2.

Same problem, it appear when i try to update `ionic_rollup` in `package.json`
