"Extends" with plugins displays a confusing error message

Tell us about your environment

• ESLint Version: 3.16.1
• Node Version: 7.6.0
• yarn Version: 0.20.3

What parser (default, Babel-ESLint, etc.) are you using? babel-eslint

Please show your full configuration:

module.exports = {
  extends: ['airbnb', 'plugin:flowtype/recommended'],
  plugins: ['flowtype'],
  rules: {
    'flowtype/define-flow-type': 1,
    'flowtype/use-flow-type': 1,
    'flowtype/delimiter-dangle': [2, 'always'],
    'flowtype/semi': [2, 'always'],
  },
  settings: {
    flowtype: {
      onlyFilesWithFlowAnnotation: true,
    },
  },
};

package.json:

...
"eslint-plugin-flowtype": "2.30.0",
...

What did you expect to happen? My code would be linted with ‘flowtype’ rules.

What actually happened? Please include the actual, raw output from ESLint. I get:

Oops! Something went wrong! :(

ESLint couldn't find the config "plugin:flowtype/recommended" to extend from. Please check that the name of the config is correct.

Thanks @danny-andrews for confirming, that’s what I was experiencing. It will be fixed in https://github.com/eslint/eslint/pull/8196

@danny-andrews What do you mean by “it works”? The report is complaining about the config, when the actual error I get if I revert the commit is “Error: Cannot find module ‘babel-eslint’” Is that what you mean?

You must have eslint-plugin-flowtype installed and use it in your eslintrc config in order to see the error message I’m reporting.

To clarify: On 360dbe4: without babel-eslint installed: ESLint couldn't find the config "plugin:flowtype/recommended" to extend from. Please check that the name of the config is correct. with babel-eslint installed: Works as expected with no errors.

On Pre-360dbe4: without babel-eslint installed: Cannot find module 'babel-eslint' with babel-eslint installed: Works as expected with no errors.
