After running yarn install, you see a warning about a deprecated package. What should you do?

Delete the package from node_modules to remove the warning.

Ignore the warning because it does not affect the installation.

Re-run the install command to make the warning disappear.

Investigate the warning and consider updating the package if possible.

During an npm install, you see the message 'added 1200 packages in 30s'. What does this indicate?

The installation skipped 1200 packages due to conflicts.

The installation completed successfully and 1200 packages were installed.

The installation is still in progress and 1200 packages remain.

The installation failed because too many packages were added.

A Backstage monorepo uses Yarn workspaces. A developer wants to add a new dependency that is only used by one workspace, but they also want to ensure that the dependency is not hoisted to the root node_modules. What is the best way to achieve this?

Add the dependency to the root package.json instead.

Add the dependency to the workspace's package.json and run 'yarn install'.

Install the dependency manually in the workspace's node_modules.

Use the 'nohoist' configuration in the root package.json to prevent hoisting for that dependency.

A developer encounters an error during 'npm install' that says 'EACCES: permission denied'. The project is located in a directory owned by another user. What is the recommended way to resolve this?

Delete the node_modules folder and run 'npm install' again.

Set the npm cache to a different directory using 'npm config set cache'.

Run 'npm install' with sudo to bypass the permission issue.

Change the ownership of the project directory to the current user and run 'npm install' again.
