I ran into this earlier today
#616
Found the fixes for it.

Your angular-cli-build.js should pass an object as option to Angular2App. That object can be empty, but normally should include a vendorNpmFiles because we don't provide one for you anymore.

I'll leave this open as an issue that if no options object is passed in we should at least fail properly.

I have the same issue also
I use win 10
64bit

[zeljko-bulatovic]

@AhmedAlgonsel change angular-cli.json to be like:
{
"routes": [],
"defaults": {
"sourceDir": "src/client"
}
}

Kind regards

i am facing same problem did all what is mentioned above but not resolved.

I've create the file angular-cli.json to be like:
{
"routes": [],
"defaults": {
"sourceDir": "src"
}
}

And after that, I was able to run "ng serve", but this is not a fix. It is a workaround!
The issue is still present in angular-cli@1.0.0-beta.9, I suggest to re-open this issue until we fix the underling issue.
