You may use special comments to disable some warnings. Three ways to report errors

You may use special comments to disable (disable) some warnings. Error resolution

Cause ESLint's syntax requirements are too strict, resulting in the errors in the figure above when compiling.

You must know that this is not an abnormality in the code, but a problem with the code format. These errors will not affect the execution result of the code.

Method 1

Find the webpack.base.conf.js file in the build directory, and comment out the related eslint rules.
Turn off the coding specification check, edit webpack.base.conf.js, find the rules node under the module node, and comment out this line:

// ...(config.dev.useEslint ? [createLintingRule()] : []),

Method 2

When the project does not have a build folder, that is, it does not belong to the vue scaffolding project, please go to the index.js file under the config folder in the root directory and set the useEslint property to false.

module.exports = {dev: {useEslint: false}}

Method three

Add rules rules to module.export in the.eslintrc.js folder

rules: {'@typescript-eslint/no-unused-vars': 'off'}
