Failure Information (for bugs)

Steps to Reproduce

Please provide detailed steps for reproducing the issue.

Path 1:

1. Follow tutorial for react + express to create a repository (this worked at some point in the past, but now fails)
2. Attempt to generate additional apps/libs from cli, for example nx generate @nrwl/node:library mylibrary
3. 😭 --> Collection "@nrwl/node" cannot be resolved.

Path 2:

1. Run npx create-nx-workspace@latest repro-workspace
   • react + express
   • emotion
2. 😭 --> Collection "@nrwl/workspace" cannot be resolved.

Context

Please provide any relevant information about your setup:

• version of Nx used (Please run nx report at the root of your workspace and copy the results here if you are using Nx 8.6.1 or greater)

• 3rd-party libraries and their versions - pretty sure this is N/A
• and most importantly - a use-case that fails - See below for a new-new instal that fails with the same error

A minimal reproduction scenario allows us to quickly confirm a bug (or point out coding problem) as well as confirm that we are fixing the right problem.

I tried creating a net-new repository and everything failed with Collection "@nrwl/workspace" cannot be resolved.

When I use version 8.x the generate command works without any issues

You can pass a plugin name to it (e.g., nx list @nrwl/angular) to learn more about what the capabilities of that plugin. If that plugin not present then install it.
