Vue item error arrow function should not return assignment

Problem source

Recently, there was an error arrow function should not return assignment

when creating a startup Vue project. In fact, there is more than one error, but the final reason is that the eslint check code is referenced.

Solution:

1. Modify the code to comply with the rules of eslint (this method does not take effect here)
add {} to the code after the arrow; however, it reports this error again (I don’t know how to solve this error up to now)

2. Remove eslint
and comment ‘standard’
in the. Eslintrc.js file under the project root directory
