Failed to load config "xo/esnext" to extend from

See original GitHub issue

I always keep xo installed globally so I can usually run lint without running npm install on the local repo. This does not work for me after updating my global install to 0.25.3:

$ npm i -g xo
$ rm -fr node_modules
$ xo
Error: Failed to load config "xo/esnext" to extend from.

This seems to be caused by eslint@6, see https://eslint.org/docs/user-guide/migrating-to-6.0.0#-plugins-and-shareable-configs-are-no-longer-affected-by-eslints-location

I ran into the same issue with a global xo installation.

@coreyfarrell was right on point with his initial assessment:

This seems to be caused by eslint@6

To add another quote from ESLint’s migration guide:

If you use a global installation of ESLint (e.g. installed with npm install eslint --global) along with plugins, you should install those plugins locally in the projects where you run ESLint. […]

I got it to work after locally installing the required configs/plugins:

npm i -D eslint-config-xo

There are likely other missing packages, e.g. eslint-plugin-import etc. - They all need to be available locally.

The reason why xo@0.24.0 still works is because it uses ESLint 5. xo@0.25.0 and later uses ESLint 6.
