BABEL: Unknown option: base.Children

Question

I just did a npm update and got some new package versions. This broke my build, leaving me unable to use the default updateSchema.js from https://github.com/relayjs/relay-starter-kit/blob/master/scripts/updateSchema.js.

If anyone has already dealt with this issue, it would be greatly appreciated if you could share your solution.

I am aware that some options were removed in the new Babel 6 version (https://gist.github.com/hzoo/7e78b12d99e326f2e04f). The npm-debug.log file looks like this:

The commandline error looks like this:

Answer 1

Make sure the presets listed in your .babelrc file are installed in your node_modules folder.

For example, if you have the following in your .babelrc file:

    {
      "presets": ["react", "es2015"]
    }

You will need "babel-preset-es2015" and "babel-preset-react" installed with npm install --save.
