Typescript dependency is required and breaks my `eslint` config.

[ildella]

In my nodejs (22.x) project, I add eslint-plugin-functional 8.0.0 to devDeps, then add this line to eslint.config.js

const functional = require('eslint-plugin-functional')

will throw this error:

$ yarn lint

Oops! Something went wrong! :(

ESLint: 9.20.1

Error [ERR_MODULE_NOT_FOUND]: Cannot find package 'typescript' imported from /home/ildella/projects/frankie/backend/node_modules/ts-api-utils/lib/index.js

What is strange is that eslint-plugin-jest also depende on ts-api-utils but it does not create this problem.
So I assume some workaround should exists.

Any tip? Thanks.

I can't recreate the issue by just importing eslint-plugin-functional. Do you happen to be using rules that require TypeScript. Many of the rules of this plugin only work if you are using TypeScript.

[ildella]

I do not load any rules, it breaks just requiring the plugin in eslint.config.js .
I'll try to reproduce it in a new clean repo.
