“No ESLint configuration found” error

Question

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

> $ grunt eslint
Running \"         


        

Answer 1

Run the command ember init. When it asks for overwriting the existing file(s). Type n to skipping overwriting the file. Now it will automatically create required files like .eslintrc, etc.

For me the same issue occurred when i copied my folder except dist, dist_production and node_modules folder to another system and tried running ember build.

Answer 2

We faced this problem today and realized, that the issue was not caused inside the project that we were working on, but inside a package that we had a link on using the command:

yarn link

Which is a feature often useful to test out new features or when trying to debug an issue in a package that manifests itself in another project. We solved it by either removing the link, or in case of ember.js disabling the developer mode of our addon package.

index.js

module.exports = {
    isDevelopingAddon: function() {
      return false;
    },
    ...
}

Answer 3

Create a new file on the root directory called .eslintrc.json file:

 {
    "parserOptions": {
         "ecmaVersion": 6,
         "sourceType": "module",
         "ecmaFeatures": {
             "jsx": true
         }
    },
    "rules": {
        "semi": "error"
    }
}

Answer 4

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.

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'}))
