graphql mismatching dependency versions

[artola]

Intended outcome:

No warnings, no wrong deps installation.

Actual outcome:

Warning:

apollo > apollo-language-server > @apollographql/graphql-language-service-interface > @apollographql/graphql-language-service-utils@2.0.2" has incorrect peer dependency "graphql@^0.12.0 || ^0.13.0 || ^14.0.0".

How to reproduce the issue:

apollo install graphql v15 and installs apollo-language-server that includes @apollographql/graphql-language-service-interface but requires:

 "peerDependencies": {
    "graphql": "^0.10.0 || ^0.11.0 || ^0.12.0 || ^0.13.0 || ^14.0.0"
  },

Package.json:

{
  "name": "apollo-language-server",
  "dependencies": {
    "@apollographql/graphql-language-service-interface": "^2.0.2",
    "graphql": "14.0.2 - 14.2.0 || ^14.3.1 || ^15.0.0",

Versions

verified with:
apollo v2.32.11 and v2.32.13 (latest)

👍 - I think NPM 7's peer dependency resolution will cause this problem for more folks.

EDIT: confirmed - if you use npm install --legacy-peer-deps it will force apollo-language-server to resolve to graphql: "^15" which is technically invalid.

I created a little sample repo that shows this issue using GitHub actions: https://github.com/blimmer/apollo-bug-report/actions

Note that NPM 6 and NPM 7 (with --legacy-peer-deps flag) work, but NPM 7 is broken when used without opting into the legacy behavior.

I believe the issue lies here:
In node_modules/apollo-language-server/package.json (https://github.com/apollographql/apollo-tooling/blob/master/packages/apollo-language-server/package.json)

"@apollographql/graphql-language-service-interface": "^2.0.2"

The current version of that interface appears to be 2.8.3 under a different package name, which is why it's not updating.: https://github.com/graphql/graphiql/blob/main/packages/graphql-language-service-interface/package.json

That version is properly setup for graphql@15.5.

Many thanks @blimmer for the temporary workarounds. My new savior (and hopefully temporary) command npx npm@6 install.

Oh, and then I find a few similar entities...
