What is the current behavior?

After a fresh install (with specific package versions) yarn check fails with the error: "acorn" is wrong version: expected "2.7.0", got "6.1.1".

The issue appears to be that this specific version of [email protected] expects acorn@^2.4.0 but [email protected] expects acorn@^6.0.5 and [email protected] expects ^6.0.7.

package.json

{
  "dependencies": {
    "jsdom": "7.2.2",
    "webpack": "4.33.0",
    "webpack-bundle-analyzer": "3.3.2"
  }
}

Steps

> yarn init
> yarn add [email protected] [email protected] [email protected]
> yarn check
yarn check v1.16.0
error "acorn" is wrong version: expected "2.7.0", got "6.1.1"

info Visit https://yarnpkg.com/en/docs/cli/check for documentation about this command.

What is the expected behavior?

yarn check passes with no errors since both versions of acorn is installed to satisfy package dependencies.

Please mention your node.js, yarn and operating system version.

yarn version: 1.16.0
node version: 10.8.0
OS: macOS 10.13.6

Found this issue when searching for:

warning "chokidar#fsevents#node-pre-gyp@^0.12.0" could be deduped from "0.12.0" to "[email protected]"

I can't get that warning to go away despite having having only version of node-pre-gyp in my yarn.lock.
