Config for rule "import/extensions" is invalid

[efueger]

Actual Behavior

When using Code Climate's eslint-4 channel, with the following dependencies in the package.json:

• babel-eslint@8.2.3

• eslint@4.18.2

• eslint-plugin-import@2.9.0

• package.json.txt

• eslintrc-import error.txt

With this in the .eslintrc file:

"import/extensions": [
      "error",
      "ignorePackages",
      {
        "js": "never",
        "jsx": "never",
      }
    ],

---

The eslint plugin fails with the following error:

/usr/src/app/lib/validate_config.js:18
throw e;
^

Error: /code/.eslintrc:
Configuration for rule "import/extensions" is invalid:
Value ["ignorePackages",{"js":"never","jsx":"never"}] should NOT have more than 1 items.
Value ["ignorePackages",{"js":"never","jsx":"never"}] should NOT have more than 1 items.
Value "ignorePackages" should be equal to one of the allowed values.
Value ["ignorePackages",{"js":"never","jsx":"never"}] should match some schema in anyOf.

Possibly resolved by bumping our eslint-plugin-import version. (we're at 2.8.0)
