eslint error cannot read property 'range' of null

I have had the same eslint issue for days now.

Everyone on the team has the same eslintrc & installed version of eslint. Their eslint works fine, mine does not.

I have tried restarting my computer, deleting node_modules, deleting anything under my user (in home directory). Nothing works.

Issue:

./node_modules/.bin/eslint *.js* 
                                                                          1 ↵  11504  10:19:47

    }
  }
}

Also, if I delete "parser": "babel-eslint" from my .eslinrc, the problem/erorr goes away, but my eslint doesn't work. I am using ES6 syntax.

UPDATE:

My solution was to use yarn instead of npm. Has solved the problem for the time being.

These .eslintrc rules fixed the problem for me:

rules : {
  "template-curly-spacing" : "off",
  "indent": ["error", 2, {
    "ignoredNodes": ["TemplateLiteral"]
  }]
}

babel-eslint has been deprecated in favor of @babel/eslint-parser. read here

Here are steps to upgrade from babel-eslint to @babel/eslint-parser:

  1. replace babel-eslint with @babel/eslint-parser:

npm

npm uninstall babel-eslint babel-eslint-plugin
npm install --save-dev @babel/eslint-parser @babel/eslint-plugin

Yarn

yarn remove babel-eslint babel-eslint-plugin
yarn add --dev @babel/eslint-parser @babel/eslint-plugin
  1. Upgrade .eslintrc.js:
module.exports = {
    ---  parser: "babel-eslint",
    +++  parser: "@babel/eslint-parser"
    plugins: [
        ---   "babel"
        +++   "@babel
    ]
};

As @Vasan mentioned, specifically, on issue 530, this was the comment that helped me to solve the issue:

Most likely the issue is causing of wrong parsing.

import(`some_path/${variable}`) // issue exists

Fix

import("some_path" + variable) // issue fixed
