Aurelia build fails - cannot find module babel-runtime

I created an issue at the Aurelia CLI repo, but figured I would ask here just in case. I'm on Windows 7 with node 7.2.1 and npm 4.0.5. The linked issue has details about dependency versions.

When I try to build via au build I get the error below. I have tried starting from scratch:

  1. Install latest node version using nvm (node 7.2.1)
  2. npm install npm -g ([email protected])
  3. npm install aurelia-cli -g ([email protected])
  4. npm install
  5. au build
> au build

TypeError: Cannot read property 'displayName' of undefined (While processing preset: "C:\\myworkingdir\\node_modules\\babel-preset-es2015-loose\\index.js")

I tried npm install babel-runtime explicitly, but that does not work.

The culprit was when I updated to [email protected] (originally Aurelia CLI has it at ^7.0.0). That project is now deprecated if using [email protected] or above.

Removing babel-preset-es2015-loose from package.json and using the new preset configuration from that link (in .babelrc file) allows Aurelia to build again.

Update

There's a pull request to fix this. Should be accepted soon.
