I am having the same issue

I believe it's a cache issue as if I remove node_module/.cache folder, I get similar results on the first run.

This issues still exists on 4.0.0-rc7 removing the cache folder as mentioned above has no effect, typescript errors (or rather warnings defined as errors) are only showed on serve not lint.

npm run serve does not honor .eslintrc rules while npm run lint does.

I have the following rules defined

{
  "rules": {
    "quotes": ["error", "double", { "avoidEscape": true }],
    "comma-dangle": ["error", "never"]
  }
}

with npm run serve I get a lot of warnings related to double quote and missing commas but npm run lint doesn't report anything.

I'm having the same issue. I have to disable "lintOnSave" in the vue config to get it to stop spamming my terminal with warnings.

[shelbykauth]

Same. I initialized a new repository with version "@vue/cli-service": "^4.0.0", on Sunday (Nov 10)
I'm using vsCode with Prettier extension installed. The default code in Hello World where the Router Links are separated by |... Prettier continually converts it to no space, and I get the yellow warning spam whenever I save, telling me I need to put in a space. But then I run the lint command and it says there are no errors.

I'd ignore it except sometimes I make legit errors and need to see them in the console.

In my case setting lintOnSave: true in vue.config.js file fixes the issue.

module.exports = {
    lintOnSave: true,
    ...
}

[ricardovanlaarhoven]

I'm getting a build error on the linter: unexpected console statement (no-console) but this error is not shown on npm run lint or when i serve the application

I would like to get all errors which i might get in npm run build in the npm run lint otherwise it goes wrong on deployment instead of when we are in development

[thedavefulton]

I'm seeing the same issue. Of particular note is getting an unused expression message for every call to expect() in my tests. I have chai-friendly installed and configured and it works great when I explicitly run the lint command, but when running tests or building or anything else I get the error message.

I'd be happy to take a run at the issue but I'm honestly not sure where to look. I tried following the CLI code to the config it's using when it runs and got quite lost.
