eslint-plugin-compat doesn't work on ESLint v6.0.0

[laukstein]

After ESLint update to v6.0.0 https://github.com/eslint/eslint/releases/tag/v6.0.0, eslint-plugin-compat is no longer working, shows :

 Error     24,24: Promise is not supported in IE 11 (compat/compat)

while having in package.json :

    }
}

#242 might related issue.

Does npm ls run successfully? If not, your dep graph is invalid, and you can't expect anything to work.

Prior to #242 being resolved, it is invalid to try to use eslint 6 with this project.

[laukstein]

Ignore this, repo packages where outdated. I succeed to update it with :

ncu -u
npm install

and now it seems working fine.

@ljharb, npm ls shows

npm ERR! peer dep missing: eslint@^3.0.0 || ^4.0.0 || ^5.0.0, required by [email protected]

Any ETA to support on ESLint v6 ?
