Npm install breaks the symlinking of packages in lerna

[shreyashah7]

• lerna bootstrap after 'npm install' will help to symlink those packages again.

[TechN8]

Running npm install also results in generation of package-lock.json files in all sub projects and if you are hoisting dependencies, will need to re-bootstrap after deleting these.

Rather than npm install consider calling lerna add <package>@<version> --scope <module-name>
