Bug: (fill in)

[dland512]

Environment

Node version: v14.17.4
npm version: 6.14.14
Local ESLint version: 7.32.0
Global ESLint version: n/a
Operating System: macOS 11.6 (20G165)

What parser are you using?

Default (Espree)

What did you do?

I created a new project and installed eslint using these options:

npx eslint --init
✔ How would you like to use ESLint? · style
✔ What type of modules does your project use? · esm
✔ Which framework does your project use? · vue
✔ Does your project use TypeScript? · No / Yes
✔ Where does your code run? · browser
✔ How would you like to define a style for your project? · guide
✔ Which style guide do you want to follow? · standard
✔ What format do you want your config file to be in? · JavaScript
Checking peerDependencies of eslint-config-standard@latest
The config that you've selected requires the following dependencies:

eslint-plugin-vue@latest eslint-config-standard@latest eslint@^7.12.1 eslint-plugin-import@^2.22.1 eslint-plugin-node@^11.1.0 eslint-plugin-promise@^4.2.1 || ^5.0.0
✔ Would you like to install them now with npm? · Yes

which resulted in this config file:

module.exports = {
  env: {
    browser: true,
    es2021: true
  },
  extends: [
    'plugin:vue/essential',
    'standard'
  ],
  parserOptions: {
    ecmaVersion: 13,
    sourceType: 'module'
  },
  plugins: [
    'vue'
  ],
  rules: {
  }
}

Notice that it has es2021: true but ecmaVersion: 13 which doesn't seem right.

What did you expect to happen?

I expect eslint to work

What actually happened?

I am getting the following error:

/temp/.eslintrc.js
  0:0  error  Parsing error: Invalid ecmaVersion

Participation

• I am willing to submit a pull request for this issue.

Additional comments

If I change the ecmaVersion from 13 to 12 it works. This makes sense since ecmascript 2021 is actually version 12.

Is this a config creation bug?
