Just for the record  if you are using eslint-plugin-vue  the correct place to add  parser    babel-eslint  is inside parserOptions param      parserOptions          parser    babel-eslint        ecmaVersion   2018       sourceType    module        https   eslint vuejs org user-guide  faq

I solved this issue by  First  installing babel-eslint using npm  npm install babel-eslint --save-dev   Secondly  add this configuration in  eslintrc file         parser   babel-eslint

In my case  im using Firebase Cloud Functions  i opened  eslintrc json and changed   quot parserOptions quot          Required for certain syntax usages    quot ecmaVersion quot   2017     to   quot parserOptions quot          Required for certain syntax usages    quot ecmaVersion quot   2020

ESLint 2 x experimentally supports ObjectRestSpread syntax  you can enable it by adding the following to your  eslintrc  docs   parserOptions        ecmaVersion   6     ecmaFeatures          experimentalObjectRestSpread   true          ESLint 1 x doesn t natively support the spread operator  one way to get around this is using the babel-eslint parser  The latest installation and usage instructions are on the project readme

Unexpected token errors in ESLint parsing occur due to incompatibility between your development environment and ESLint s current parsing capabilities with the ongoing changes with JavaScripts ES6 7   Adding the  parserOptions  property to your  eslintrc is no longer enough for particular situations  such as using  static contextTypes              react      in ES6 classes as ESLint is currently unable to parse it on its own  This particular situation will throw an error of   error Parsing error  Unexpected token     The solution is to have ESLint parsed by a compatible parser  babel-eslint is a package that saved me recently after reading this page and i decided to add this as an alternative solution for anyone coming later    just add     parser    babel-eslint    to your  eslintrc file and run npm install babel-eslint --save-dev or yarn add -D babel-eslint   Please note that as the new Context API starting from React  16 3 has some important changes  please refer to the official guide

If you have got a pre-commit task with husky running eslint  please continue reading  I tried most of the answers about parserOptions and parser values where my actual issue was about the node version I was using   My current node version was 12 0 0  but husky was using my nvm default version somehow  even though I didn t have nvm in my system   This seems to be an issue with husky itself  So    I deleted  HOME  nvm folder which was not deleted when I removed nvm earlier  Verified node is the latest and did proper parser options  It started working

Originally  the solution was to provide the following config as object destructuring used to be an experimental feature and not supported by default        parserOptions          ecmaFeatures            experimentalObjectRestSpread   true               Since version 5  this option has been deprecated   Now it is enough just to declare a version of ES  which is new enough        parserOptions          ecmaVersion   2018
