[turborepo] Combination of pnpm non-monorepo and globalDependencies causes crash

[hugo-vrijswijk]

1.9.3

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

pnpm

What operating system are you using?

Mac

Describe the Bug

Having globalDependencies in a pnpm project that is not a workspace causes a crash:

 ERROR  run failed: failed to collect global hash inputs: /Users/hvanrijswijk1/ws/test/pnpm-workspace.yaml: open /Users/hvanrijswijk1/ws/test/pnpm-workspace.yaml: no such file or directory
Turbo error: failed to collect global hash inputs: /Users/hvanrijswijk1/ws/test/pnpm-workspace.yaml: open /Users/hvanrijswijk1/ws/test/pnpm-workspace.yaml: no such file or directory

Workaround: create an empty pnpm-workspace.yaml file, though that does change the pnpm-lock.yaml structure, or move globalDependencies to each task

Expected Behavior

No crash, same behaviour as without globalDependencies

To Reproduce

Empty pnpm project, with 1 task that 'echo's something to the terminal

{
  "$schema": "https://turbo.build/schema.json",
  "globalDependencies": ["myfile.json"],
  "pipeline": {
    "echo": {
      "inputs": ["package.json"]
    }
  }
}

$ turbo echo

Remove globalDependencies and observe no crash
