What operating system are you using?

Mac

Describe the Bug

I have a relatively large private repository (65 packages and growing) in which I’m attempting to use Turbo but running into an issue with builds that I don’t encounter with any other tool. When I run turbo run build it’ll start to build and then randomly get stuck and do nothing, e.g. go halfway through building and then just stop and sit there. This doesn’t happen deterministically on the same package every time, which could be an indicator for a circular dependency but there are none.

This issue also doesn’t exists if I run the workspace build via pnpm or use https://github.com/folke/ultra-runner with ultra -r build instead of turbo run build. The setup isn’t anything crazy, it’s just the stock pnpm setup from https://github.com/vercel/turborepo/tree/main/examples/with-pnpm with 65 packages inside the packages directory.

Is there anything I could or should look at to debug this? Loving how blazing fast Turbo is but this build issue prevents me from fully utilising it.

Expected Behavior

Finish the build process without any issues like pnpm and ultra do.

To Reproduce

It’s a relatively large private repository so not sure what the best way to provide reproduction steps would be. The configuration is fairly simple:

{
  "$schema": "https://turborepo.org/schema.json",
  "pipeline": {
    "build": {
      "dependsOn": [
        "^build"
      ],
      "inputs": [
        "src/**/*.ts",
        "package.json"
      ],
      "outputs": [
        "distribution/**"
      ]
    }
  }
}
