Uninstalling local packages
You can remove a package from your node_modules directory using npm uninstall <package>:
npm uninstall lodash
To remove it from the dependencies in package.json, you will need to use the save flag:
npm uninstall --save lodash
Note: if you installed the package as a "devDependency" (i.e. with --save-dev) then --save won't remove it from package.json You have use --save-dev to uninstall it.
