Installation warnings and errors on Ubuntu Xenial 16.04.x

Is this a bug report?

Yes

Can you also reproduce the problem with npm 4.x?

• The primary issue is while using NPM v8.0.3
• I have tested with NPM v3.10.10 (node v6.11.0) and received the following warnings, but no errors:

npm WARN optional SKIPPING OPTIONAL DEPENDENCY: fsevents@1.0.17 (node_modules/react-scripts/node_modules/fsevents): npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for fsevents@1.0.17: wanted {“os”:“darwin”,“arch”:“any”} (current: {“os”:“linux”,“arch”:“x64”}) npm WARN optional SKIPPING OPTIONAL DEPENDENCY: fsevents@^1.0.0 (node_modules/chokidar/node_modules/fsevents): npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for fsevents@1.1.2: wanted {“os”:“darwin”,“arch”:“any”} (current: {“os”:“linux”,“arch”:“x64”})

Thanks for the update. 😃

FWIW Node 8 should work with latest version. But you still need to downgrade npm to 4.x because 5.x is too buggy right now.
