 NX  Generating @nx/workspace:convert-to-monorepo


 NX   The following projects are defined in multiple locations:

- PROJECT_NAME:
  - .
  - apps/PROJECT_NAME

To fix this, set a unique name for each project in a project.json inside the project's root. If the project does not currently have a project.json, you can create one that contains only a name.

ProjectsWithConflictingNamesError: The following projects are defined in multiple locations:

And manual approach:

$ nx g app temp

The error message is telling you that the package.json or project.json at the root has a name set that conflicts with the package.json or project.json in the individual project's root.

You can fix the error by updating either name.

Can you create a reproduction for us the better diagnose the root cause of this?

@AgentEnder thanks for the prompt reply!
It was indeed the name in package.json
I had not changed it since the initial generation, so I guess if you would create a standalone repo with default values and then run nx g convert-to-monorepo it will cause the same error.

Didn't know nx would also look there for project information.

I could run it, but ran into a couple of things I had to fix manually:

• /tsconfig.json and /.eslintrc.json were missing => copied manually from another project
• .eslintrc.base.json referred itself, causing call stack exceeded
• Had to manually fix Tailwind & Storybook

Not major, the generator definitely helped. Thanks again.
