Following this tutorial https://cli.vuejs.org/guide/prototyping.html

cli-plugin-eslint api directory getting resolved as current project directory https://github.com/vuejs/vue-cli/blob/dev/packages/%40vue/cli-plugin-eslint/index.js#L8 and so eslintPkg becomes undefined.

I added plugin to the current directory by vue add @vue/eslint and dev server started normally.

I'm having the same issue with vue serve. Is there a known workaround for this bug?

I am planning to use the zero config vue serve in a training next week, so, it's a bit of a surprise that it is no longer working.

[pbastowski]

The temporary solution is to use POI. It is just as easy as vue-cli to use, but works right this moment.

[joeirimpan]

Just do npm install eslint inside the project. It should work.

@joeirimpan solves the issue, but how come?

[pbastowski]

@joeirimpan
Thanks. That's the only place I did not try installing eslint.
This moves in the right direction, but for me still complains about missing stylus-loader. And I'm not even using stylus or any special css pre-processor.

Must be introduced by this commit c500512
I'll try to fix it asap.

Installing eslint locally works, but of course this still negates the instant prototyping feature.

[voyera]

Just do npm install eslint inside the project. It should work.

Thank you for that! Still curious as to why this solves the issue and why it's not documented.

[haoqunjiang]

Fixed in the latest release. Please reinstall the @vue/cli-service-global package.

[pbastowski]

Thanks for the quick response, that fixed the issue with eslint.

I also followed the tutorial on my windows machine with the same error description from above.

Im using Version 4.0.2 (+ @vue/cli-service-global@4.0.2) , installed today :O
Other versions: Node v10.8 / npm 6.2

I can later try using this on a mac. 👍
