Babel transpiling failing for client.js?

Hi, I'm probably misinterpreting the error, here's why I get on `npm run dev`:

Before I got to this point, I couldn't get server code to transpile as well. I had to add some options to .babelrc:

`
{
"presets": [
"es2015",
"react",
"stage-0"
],
"plugins": [
"transform-decorators-legacy"
]
}
`

I'll post package.json if needed (added the above presets and plugin there).

npm version is 3.8.5
node is 5.10.0

What did I do wrong?
