I think the problem is that you are trying to use the deprecated babel-eslint parser, last updated a year ago, which looks like it doesn’t support ES6 modules. Updating to the latest parser seems to work, at least for simple linting.
So, do this:
- In package.json, update the line
"babel-eslint": "^10.0.2",to"@babel/eslint-parser": "^7.5.4",. This works with the code above but it may be better to use the latest version, which at the time of writing is 7.16.3. - Run
npm ifrom a terminal/command prompt in the folder - In .eslintrc, update the parser line
"parser": "babel-eslint",to"parser": "@babel/eslint-parser", - In .eslintrc, add
"requireConfigFile": false,to the parserOptions section (underneath"ecmaVersion": 8,) (I needed this or babel was looking for config files I don’t have) - Run the command to lint a file
Then, for me with just your two configuration files, the error goes away and I get appropriate linting errors.
