React-starter-kit: Babel plugin unknown error on fresh install

[zoltan-molnar]

I tried to test different branches: master, feature/redux
When I hit npm run I got the following:

C:\Users\mzol1\projects\speed5online\redux_app>npm start

> @ start C:\Users\mzol1\projects\speed5online\redux_app
> babel-node tools/run start

Does anybody have an idea why this is happening?

When I run babel-node:

You have mistakenly installed the `babel` package, which is a no-op in Babel 6.

Babel's CLI commands have been moved from the `babel` package to the `babel-cli` package.

    npm uninstall babel
    npm install babel-cli

See http://babeljs.io/docs/usage/cli/ for setup instructions.

you have to change package.json and add a babel-cli dependencie "babel-cli": "6.18.0",

I follow the instructions to install the environment... but seems that babel is not capable of reading a plugin syntax-trailing-function-commas, or even to install it.

Ran into the same issue this morning, caused by an outdated install of Node on Win10.

This seems to have taken care of the problem for me.

• Update Node to latest stable version.
• Delete node_modules folder.
• npm install
• npm start

@gbersani can you let us know which versions you got this working on? currently experiencing the same problem on npm 4.0.5 node (tried both v6.9.4, v7.4.0). Tried with just npm and again with yarn. No luck. It seems installing the plugin through npm install --save-dev babel-plugin-syntax-trailing-function-commas works. It's now throwing the error:

module.js:472
    throw err;
    ^

Fresh install. Any ideas?
