@babel/parser throw an error when parsing object shorthand property async get () after updating to version 7.11.1

index.js

export default {
  async get () {}
};

package.json

{
  "name": "babel-test",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "dependencies": {},
  "devDependencies": {
    "@babel/cli": "^7.10.5",
    "@babel/core": "^7.10.3"
  },
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1",
    "babel": "babel index.js"
  },
  "author": "",
  "license": "ISC"
}

when running npm run babel, I got an error below

{ SyntaxError: /Users/icefox/Desktop/babel-test/index.js: Unexpected token (2:11)

It works fine with async with property name except get, and older version of @babel/parser, and in latest chrome and node v8, it turns out a valid syntax

Fixed in @babel/parser 7.11.2.

npm update @babel/parser --depth 999

If you use yarn, you can either manually remove @babel/parser entries in yarn.lock and re-run yarn install or use yarn-deduplicate

# pick up 7.11.2, don't worry it will be removed later
yarn add @babel/parser
# yarn-deduplicate will resolve @babel/parser: ^7.11.1 to 7.11.2
yarn-deduplicate --packages @babel/parser yarn.lock
# remove `@babel/parser` from your package.json, it will be still in your node_modules
yarn remove @babel/parser

For temporary fix right now we are using this one:

"resolutions": {
  "@babel/core/@babel/parser": "7.11.0"
}
