Cannot find module 'babel-runtime/core-js/object/keys'

[DanielPritchard]

I am getting this error after updating to version 3.0.4 (it also occurs for 3.0.5)

You probably need to reinstall your node_modules

[cscott]

No, I'm getting the same thing in a clean build on travis. One of your dependencies broke w/ the jscs 3.0.5 release it seems.

It seems to be cst@0.4.1 which kills jscs, it dropped its babel deps.

[cscott]

Root cause seems to be https://github.com/cst/cst/issues/111, which dropped support for node < 4.

[markelog]

Should be fine now

[mattgrande]

This reared it's head for me again today, since cst eliminated support for older versions of node again in v0.4.8 (and I'm still on Node 0.10.33...)

For anyone else coming here, I got around this by creating an npm-shrinkwrap.json file, and setting the cst version to 0.4.7:

{
  "dependencies": {
    "jscs": {
      "version": "3.0.7",
      "from": "jscs@3.0.7",
      "dependencies": {
        "cst": {
          "version": "0.4.7",
          "from": "cst@^0.4.3"
        }
      }
    }
  }
}

(If you've never used shrinkwrap before, I recommend reading here: https://docs.npmjs.com/cli/shrinkwrap)

[hzoo]

@mattgrande it didn't remove support yet - the package didn't publish a lib directory so there were no files https://github.com/cst/cst/issues/151

[mattgrande]

Oh! I just assumed it was the same issue, should've checked cst to be sure.

Looks like they've released 0.4.9, so this is no longer needed!
