Nx Cannot find project 'my-app' although package.json is present

[GaryB432]

Current Behavior

Nx "Cannot find" my project

Expected Behavior

I expect Nx to run my target in apps/my-app/package.json

Steps to Reproduce

npx create-nx-workspace@latest ws --preset apps --no-nx-cloud
cd ws

add apps/my-app/package.json

{
  "name": "my-app",
  "version": "0.0.0",
  "scripts": {
    "echo": "echo \"OK\""
  }
}

continue

nx echo my-app

# NX Cannot find project 'my-app'

cd ./apps/my-app
npm run echo

# OK

cd ../..
nx echo my-app

# NX Cannot find project 'my-app'

Failure Logs

Can you run nx graph and send a picture of the graph?

[GaryB432]

nx graph

NX   ENOENT: no such file or directory, open \D:\ws\apps\my-app\project.json'

Because of the error the Nx daemon process has exited. The next Nx command is going to restart the daemon process. If the error persists, please run "nx reset".

and an `cmd` window left open with `[process exited with code 1 (0x00000001)]` 

These results repeat if I run `nx reset`

That leading path separator looks suspicious.

[GaryB432]

Was that ☝🏻all you needed? Is this still blocked?

[AgentEnder]

Hey, sorry, haven't gotten back to this just yet. Looking at it now, can you try running again with the following two environment variables set?

NX_DAEMON=false
NX_VERBOSE_LOGGING=true

[GaryB432]

Thanks for looking (I see btw that you are a fellow midwesterner!)

Got a good stack trace from nx graph

Yeah.. that project.json file def does not exist :)

[AgentEnder]

It sounds like that file definitely should exist. If you look in workspace/angular.json is there a project definition that points to apps/my-app?

[GaryB432]

ahhh sure enough. Hmm such a flurry I don't know how that got there. I only executed the couple lines I put in the repro-steps above.

[GaryB432]

Latest findings...

Environment variables set as above

Same repro steps as above, i.e., create-nx-workspace* and create package.json

Run nx echo my-app gives 'Cannot find project my-app but with no verbose logging

No workspace json created.

nx graph shows no errors and a graph with no projects which seems consistent with my situation

* however this did give Cannot read properties of undefined (reading 'create') but seemed to create my workspace. I guess that's another issue.

[AgentEnder]

Yeah, in 15 you'd need to setup yarn / npm / pnpm workspaces to enable the project inference. We look at those patterns.

[GaryB432]

This seems to work in earlier 15 like 15.0.3 but that did it. Just checking my understanding....

Nx finds project.jsons by scanning but a worskspaces key is needed in root package.json for it to find my package.jsons.

Maybe just a docs label on this then. Thanks for the help!

[AgentEnder]

https://github.com/nrwl/nx/pull/13203 this should contain that info.

I'm going to close this out since we diagnosed the issue successfully.
