Solution 1

Try to swap config with configFile. Then :

Create eslint.json file and
Point the right location of it (relative to Gruntfile.js file)
Place some configuration in that file (eslint.json), i.e.:

{
    "rules": {
        "eqeqeq": "off",
        "curly": "warn",
        "quotes": ["warn", "double"]
    }
}

Solution 2

The error you are facing is because your configuration is not present. To configure the eslint type

eslint --init

then configure as your requirement.

then execute the project again.

Solution 3

I've had the same error. It seems to need configuration.

Go to your project root & run in terminal

./node_modules/.bin/eslint --init

Solution 4

I hade the same problem with Gulp and running "gulp-eslint": "^3.0.1" version. I had to rename config: to configFile in Gulp task

.pipe(lint({configFile: 'eslint.json'}))

Solution 5

For those having the same problem, this is how we've fixed it.

Following the Requiring Configuration to Run migration procedure, we had to rename eslint.json to .eslintrc.json which is one of the default ESLint config file names now.

We've also removed the config grunt-eslint option.

The sand was soft, the ocean glass, But I was still just me. Then pelicans in threes and fours, Glided by like dinosaurs, An otter basked upon its back, And dived to find another snack. The sun corpuscular and bright, Cast down a piercing shaft, And conjured an inspiring sight On glinting, bobbing craft. Two mermaids rose up from the reef, Out of the breaking waves. Their siren song was opium grief, Their faces from the grave. The mermaids asked a princely kiss To free them from their spell. I said to try a poet’s bliss. They shrugged and bid farewell. The sun grew dark and sinister, In unscheduled eclipse. As two eight-headed aliens Descended in their ships. They said the World was nice enough But didn’t like our star. And asked the way to Betelgeuse, If it wouldn’t be too far. Two whales breached far out to sea, And flew up to the sky, The crowd was busy frolicking, And didn’t ask me why. Today I left my phone at home, On the worst day, you’ll agree. If only I had pictures, If only you could see. Not everything was really there, I’m happy to confess, But I still have the memories, Worth more than tweets and stress. Today I left my phone at home, I had no shakes or sorrow. If that is what my mind can do, It stays at home tomorrow. Gavin Miller

Recently, we've upgraded to ESLint 3.0.0 and started to receive the following message running the grunt eslint task:

> $ grunt eslint
Running "eslint:files" (eslint) task
Warning: No ESLint configuration found. Use --force to continue.

Here is the grunt-eslint configuration:

var lintTargets = [
    "<%= app.src %>/**/*/!(*test|swfobject)+(.js)",
    "test/e2e/**/*/*.js",
    "!test/e2e/db/models/*.js"
];
module.exports.tasks = {
    eslint: {
        files: {
            options: {
                config: 'eslint.json',
                fix: true,
                rulesdir: ['eslint_rules']
            },
            src: lintTargets
        }
    }
};

What should we do to fix the error?

Yeah, configFile worked as well. Looks like we were using config which did not have any effect, but worked since eslint 2 searched for it by default. Now that we've migrated to eslint 3 and the default config filenames changed, eslint does not find the config automatically and this reveals that we should have used configFile from the beginning. This is the theory I have now. Thanks!

You're welcome. I just tackled the configuration recently, so avoided legacy problems.
