Unable to generate-types

[darranhayes]

Hi Matt, I've no expectation on you to try and fix this, I'm reaching out in case you happen to already know a fix from experience, and if you can share I'd be very grateful.

I'm on windows 10, running node v14.15.1 (was running v12.* earlier, same problem), and I'm not able to generate-types on a clone of your repo, with a fresh npm install. Error included below.

I've also tried "npm ci" to install only the exact specified versions from your package-lock.json, I've switched to yarn and tried looking for the conflicting dependencies where possible, all with no joy. I also cannot find a recent version of this issue on the code-gen/cli repository, although they had it last year.

Can you share your OS and NodeJS & NPM versions, and if different, then I'll set up a similar WSL instance and try again.

Thanks for any help! D

Ensure that there is only one instance of "graphql" in the node_modules directory. If different versions of "graphql" are the dependencies of other relied on modules, use "resolutions" to ensure only one version is installed.

I haven't seen this before. Did you edit the schema?

Also you have a yarn doc there, you might try using yarn if you are familiar with it rather than npm. I usually do.

If you tried yarn, delete node_modules first.

Thanks Matt. I tried nuking node_modules, switched to yarn, used various tricks to look for the clash. At this stage I think it's an environment specific issue. I'll spin up a Linux environment and see if there's a change. Thanks again.
