ENOWORKSPACES when publishing from workspace

[karlhorky]

Description

Publishing one of the packages from a workspace like packages/react-scripts in a create-react-app fork leads to a ENOWORKSPACES error when running the npm config get registry command:

$ np --yolo

✖ Error: Command failed with exit code 1: npm config get registry
npm ERR! code ENOWORKSPACES
npm ERR! This command does not support workspaces.

This is a regression since a few months - in April / May 2023 we were able to publish these packages without problems.

Steps to reproduce

1. np --yolo or np in a package inside of a workspace

Expected behavior

np works in a package inside of a workspace without errors

Environment

np - 8.0.4
Node.js - 18.17.1
npm - 9.6.7
Git - 2.39.2
OS - macOS Ventura 13.5.2

Workaround (complicated)

1. Move workspace package outside of the monorepo
2. Create new GitHub repo
3. git init
4. git remote add origin <repo remote URL>
5. git push --set-upstream origin main
6. np
