ModuleBuildError: Module build failed: SyntaxError: Unexpected token

[MoOx]

Recently (since yesterday), new install are broken with this kind of message

✔ ModuleBuildError: Module build failed: SyntaxError: Unexpected token (8:4)

   6 | const store = createStore(
   7 |   combineReducers(phenomicReducers),
>  8 |   { ...(typeof window !== "undefined") && window.__INITIAL_STATE__ },
     |     ^
   9 | )

This is due to latest babel-loader version (6.3.1). This PR babel/babel-loader#379 introduces a regression for us somehow.

See babel/babel-loader#381 for a resolution.

Meanwhile, use babel-loader@6.3.0, not 6.3.1

Should be fixed by babel-loader@6.3.2
