What package manager are you using / does the bug impact?

npm

What operating system are you using?

Windows

Which canary version will you have in your reproduction?

1.13.1-canary.0

Describe the Bug

Running turbo command, that invokes tsx watch FILE.ts, when FILE.ts includs reference from googleapis npm package results in no output, and no code being run. Removing watch flag makes it work properly. This worked properly on 1.12.5, and breaks on 1.13+.

Expected Behavior

Referencing googleapis in Typescript code should not freeze executing that file when run with tsx watch

To Reproduce

apps/backend/index.ts:

import { google } from 'googleapis';
console.log({ google })

apps/backend/package.json:

{
  "name": "api",
  "scripts": {
    "dev": "tsx watch src/index.ts",
    "build": "npx tsc"
  },
  "dependencies": {
    "googleapis": "^134.0.0"
  },
  "devDependencies": {
    "tsx": "^4.7.1",
    "typescript": "^4.9.4"
  }
}

./turbo.json:

{
  "$schema": "https://turbo.build/schema.json",
  "pipeline": {
    "build": {
      "dependsOn": ["prebuild", "^build"],
      "outputs": ["output-file.txt", "dist/**"]
    },
    "prebuild": {},
    "lint": {},
    "type-check": {},
    "dev": {
      "cache": false
    }
  }
}

./package.json:

{
  "name": "my-turborepo",
  "description": "A barebones Turborepo example for working with Task Graphs.",
  "devDependencies": {
    "turbo": "canary"
  },
  "scripts": {
    "dev": "turbo run dev"
  },
  "packageManager": "npm@10.1.0",
  "workspaces": [
    "apps/*",
    "packages/*"
  ]
}

Running npm run dev should result in logging the content of the google object from googleapis. Currently it hangs:

This works fine in 1.12.5, as well when manually executing npx tsc watch src/index.ts

Additional context

Hi @osztenkurden, could you try adding "persistent": true to your dev task? Since it's a long running task, it needs that option to run correctly. Let me know if that helps!

[osztenkurden]

@NicholasLYang Updated turbo.json so it looks like that:

{
  "$schema": "https://turbo.build/schema.json",
  "pipeline": {
    "build": {
      "dependsOn": ["prebuild", "^build"],
      "outputs": ["output-file.txt", "dist/**"]
    },
    "prebuild": {},
    "lint": {},
    "type-check": {},
    "dev": {
      "cache": false,
      "persistent": true
    }
  }
}

However, still freezes.

Can you confirm that the script works without the use of turbo?

I just tried cloning your repo and cd apps/backend && npm run dev resulted in the same behavior without use of turbo:

[osztenkurden]

@chris-olszewski Yep, it does, to be sure I verified both Terminal/CMD and Git Bash, both console log out:

Thats very weird, because it only starts happening on Turbo 13

I attached screens for working npm run dev in Terminal, Git Bash, and not working while using turbo

[chris-olszewski]

Is that error message always present in your turbo runs?

[osztenkurden]

No, forgot to run npm i for the workspaces / packages, I did it, warning went away and freezing still happens

[chris-olszewski]

Okay, I've been able to track this down to a weird interaction with Windows, tsx watch, and tasks that aren't hooked up to a PTY.

Not exactly sure what the fix is at this time, but one workaround is to use the new experimental UI which allows for tasks on Windows to be hooked up to a pseudoterminal. Another workaround is to forcibly close stdin by changing the dev command to take NUL as stdin e.g. "dev": "tsx watch src/index.ts < NUL"
