💻 Code

Something has significantly changed from typescript 5.4.5 to 5.5.0. yarn config set nodeLinker pnp was working fine together with yarn exec tsc. Today I had to switch to yarn config set nodeLinker node-modules in order to use yarn exec tsc together with typescript 5.5.0.

Typescript config is standard:

{
  "include": ["src/**/*.ts"],
  "compilerOptions": {
    "target": "esnext",
    "lib": ["esnext"],
    "module": "NodeNext",
    "rootDir": "src",
    "moduleResolution": "nodenext",
    "outDir": "dist",
  }
}

🙁 Actual behavior

If you are trying to run yarn exec tsc (when yarn v4 is in pnp mode) than typescript 5.5.0 will fail with something like:

error TS2503: Cannot find namespace 'NodeJS'
error TS2304: Cannot find name 'setTimeout'
error TS2304: Cannot find name 'clearTimeout'

🙂 Expected behavior

yarn exec tsc (when yarn v4 is in pnp mode) works without errors.

Additional information about the issue

Did you break something related to node_modules dir in typescript 5.5.0? Thank you.

Sorry, it is hard to provide playground, because I see no sandboxes supports yarn in pnp mode. Please just use the following shell script:

mkdir ts-5.5.0 && cd ts-5.5.0
echo '{ "name": "bug-1", "private": true, "dependencies": { "typescript": "5.5.2", "@types/node": "*" } }' | jq > package.json
yarn set version stable
yarn config set nodeLinker pnp
yarn install
mkdir src && mkdir dist
echo 'setTimeout(() => {}, 0);' > src/bug.ts
echo '{ "include": ["src/**/*.ts"], "compilerOptions": { "target": "esnext", "lib": ["esnext"], "module": "NodeNext", "rootDir": "src", "moduleResolution": "nodenext", "outDir": "dist" }}' | jq > tsconfig.json
yarn exec tsc

Result is the following:

src/bug.ts:1:1 - error TS2304: Cannot find name 'setTimeout'.

You can fix it by using the following shell script:

yarn config set nodeLinker node-modules
yarn install
yarn exec tsc

And it will finish without errors.

This happens with roughly every new TypeScript release but it's not on the TypeScript team to handle this.

You'll need to wait for yarnpkg/berry#6349 to be released or if you want you can use that PR version of Yarn by running the following in your project:

yarn set version from sources --branch 6349
yarn install

yarn exec tsc

You can "simplify" that to yarn tsc.

@merceyz, Thank you, it works perfect. Lets wait until it will be released.
