[turborepo] Configuring globalDependencies in a non-monorepo

[stefanofa]

1.8.3

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

Yarn v1

What operating system are you using?

Mac

Describe the Bug

I tried to add turborepo to an existing non-monorepo next project.
The turbo.json configuration is as follows:

{
  "$schema": "https://turbo.build/schema.json",
  "globalDependencies": ["**/.env.*local"],
  "pipeline": {
    "build": {
      "outputs": [".next/**"]
    },
    "lint": {},
    "dev": {
      "cache": false,
      "persistent": true
    }
  }
}

But when I run

yarn turbo build

I get the following error:

run failed: failed to collect global hash inputs: package.json: no workspaces found. Turborepo requires Yarn workspaces to be defined in the root package.json
Turbo error: failed to collect global hash inputs: package.json: no workspaces found. Turborepo requires Yarn workspaces to be defined in the root package.json
error Command failed with exit code 1.

If I remove

"globalDependencies": ["**/.env.*local"],

from the configuration, seems to work instead.

I tried to do the same with the official example of non-monorepo and the same error occurs.

Expected Behavior

Being able to use turborepo in a 'non-monorepo' by having the configuration option globalDependencies working.

To Reproduce

• Install Turborepo non-monorepo starter :

npx degit vercel/turbo/examples/non-monorepo non-monorepo
cd non-monorepo
yarn
git init . && git add . && git commit -m "Init"

• Edit the file turbo.json by adding the option "globalDependencies": ["**/.env.*local"].

• Run:

yarn turbo build

Hi! We are working on improving the single-package workflow with turborepo. @tknickman has been working on a PR that addresses some of this and will follow up to make sure that this exact case is covered.

I added a failing test for this in #4240 and left a pointer on how to fix it. Will try to get back to it some time next week, but feel free to pick it up @stefanofa if you have an idea of how to fix!
