@types/react-dom dependency to @types/react causes version mismatch with @types/react

[tomaszs]

According to this post https://stackoverflow.com/a/52422489/38940 and validated by me:

"devDependencies": {
  "@types/react": "^15.0.16",
  "@types/react-dom": "^0.14.23"
  ...
}

resolve to different versions of @types/react:

"@types/react-dom@^0.14.23":
  version "0.14.23"
  resolved "https://registry.yarnpkg.com/@types/react-dom/-/react-dom-0.14.23.tgz#cecfcfad754b4c2765fe5d29b81b301889ad6c2e"
  dependencies:
    "@types/react" "*"

"@types/react@*":
  version "16.4.14"
  resolved "https://registry.yarnpkg.com/@types/react/-/react-16.4.14.tgz#47c604c8e46ed674bbdf4aabf82b34b9041c6a04"
  dependencies:
    "@types/prop-types" "*"
    csstype "^2.2.0"

"@types/react@^15.0.16":
  version "15.6.19"
  resolved "https://registry.yarnpkg.com/@types/react/-/react-15.6.19.tgz#a5de18afe65b0f29767328836b48c498a5d3a91b"

```

react-dom expects latest @types/react, while @types/react can be installed in other version. Since both versions are downloaded, there are conflicts between these versions. Maybe @types/react-dom should expect specific version of @types/react to solve this problem

Hi @tomaszs! This repo does not contain TypeScript Typings, they originate from https://github.com/DefinitelyTyped/DefinitelyTyped

Either way, your problem is in the user land. Instead of

"devDependencies": {
  "@types/react": "^x.x.x",
  "@types/react-dom": "^y.y.y"
  ...
}

it should always be

"devDependencies": {
  "@types/react": "^x.x.x",
  "@types/react-dom": "^x.x.x"
  ...
}

Delete all lockfile entries for @types/react and run yarn again. This should result in a single version.

The types are hosted in a different repository. In the future please open type related issues in the https://github.com/DefinitelyTyped/DefinitelyTyped repository.
