Installing vue cli issue

Question

What does that mean, what do I need to do with this thing. Is it a problem or a normal thing when installing vue?

 > nodemon@1.17.5 postinstall C:\\Program Files\\nodejs\\node_modules\\@vue\\cli\\node_modules\\nodemon > node bin/postinstall || exit 0 npm WARN optional SKIPPING OPTIONAL DEPENDENCY: fsevents@1.2.4 (node_modules\\@vue\\cli\\node_modules\\fsevents): npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for fsevents@1.2.4: wanted {"os":"darwin","arch":"any"} (current: {"os":"win32","arch":"x64"}) + @vue/cli@3.0.0-rc.3 added 612 packages in 136.015s 

Answer 1

As NPM points out:

npm WARN optional SKIPPING OPTIONAL DEPENDENCY

It's an optional dependency. I won't cause you any trouble while developing.
