Running npm install on a workspace project works correctly the first time.

Running npm install on the workspace a second time deletes everything in the workspace's node_modules directory.

Running npm install a third time says the install is "up to date" even though nothing is installed.

Expected results

It is expected that npm install works similarly for a workspace project as for a regular, non-workspace project.

i.e. It is expected that running npm install again on a workspace project should install new dependencies that have been added to workspace package.json files or leave the installed dependencies as-is if there are no changes.

It is unexpected that npm install empties out /node_modules when running the second time.

To re-install dependencies into the workspace project you must delete the workspace /node_modules/* and /package-lock.json or run npm update.

It is unexpected that the user should run npm install the first time but remember to run npm update any subsequent time as this is different to how npm works inside a regular project (i.e. it is expected that it is possible to run npm install multiple times in a workspace project).

1. Clone this repository
2. From this workspace directory run npm install
   • dependencies are installed correctly
3. Run npm install again
   • all packages are removed from node_modules
4. Any subsequent npm install says that it is up to date even though node_modules is empty

** Final result:**

npm_modules is empty except for a .package-lock.json file and nothing is installed.
