Node.js Question

Module build failed: ReferenceError: [BABEL] Unknown option: /Users/Will/.babelrc.presets

So I am totally baffled by this. My team is running on the same branch, same commit of code. I'm the only one having this issue. Here's the full stack trace:

Module build failed: ReferenceError: [BABEL] /Users/Will/Brandzooka/visibl-front_end/node_modules/eslint-loader/index.js!/Users/Will/Brandzooka/visibl-front_end/app/index.jsx: Unknown option: /Users/Will/.babelrc.presets

I've come across multiple answers that all relate to Babel 6 usage, which doesn't currently apply to me.

I've tried:


  • Uninstalling and reinstalling node and npm versions (via nvm)

  • Blowing away all the node modules, and reinstalling

  • npm cache clean

  • Blowing away repo, and re-cloning

  • For good measure, restarting my machine



Im running node v0.12.9 & npm v2.14.9

Any hot ideas out there? 3 hours in, I can't even get the error message to change.

Answer

The config path /Users/Will/.babelrc.presets means you have a .babelrc file in /Users/Will/, and it has a "presets" key because it appears to be a config file for Babel 6.

Presumably you have a .babelrc at /Users/Will/Brandzooka/visibl-front_end/.babelrc to configure your Babel 5 install, but Babel 5 does not stop traversing upward looking for other configs unless you tell it to (Babel 6 stops at the first config), so it will also look farther up and error out on the Babel 6 config in your home directory.

This leaves you with a few options:

  • Delete /Users/Will/.babelrc, because Babel config files should live in the project they apply to, not in your home.
  • If that is a no-go, open (and maybe create) /Users/Will/Brandzooka/visibl-front_end/.babelrc and make sure it has the key "breakConfig": true to tell Babel 5 to stop looking in parent directories for other config files.
