After installing with npm install -g graphql-code-generator, I get the following error:

    throw err;

I'm using npm 6.5.0 Mac OS Mojave, npm is installed from Macports.

Did you try to run npm i graphql?

[edmcman]

Oops, that fixed it. Sorry. I'm still new to npm. I thought graphql would have been installed as a dependency...

[Renaud009]

Yes graphql should indeed have been installed as a dependency ... but it's defined faultly as a devDependencie ...

[dotansimha]

@reconbot graphql is defined as devDependency and as peerDependency. We don't want to force a specific version of graphql because it might result in multiple copies of graphql (and that's not a good thing, because it will produce Also ensure that there are not multiple versions of GraphQL installed in your node_modules directory. errors).

[Renaud009]

Not listed as a peerDependency in package.json ...
Tool just cannot be used as a CLI without installing several dependencies manually at the moment.

[reconbot]

Hi, that sounds fine. Did you mean to ping me?

@dotansimha I am still getting this error even after installing graphql! angular-cli app.
UPDATE
It seems to work by using yarn gql-gen init.
