Angular-cli project cross platform build issue - node.js

Question

I've created experimental angular-cli project on Mac. Than I've moved it onto ubuntu and cant build:
$ npm install
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#1.1.3: wanted {"os":"darwin","arch":"any"} (current: {"os":"linux","arch":"x64"})
& start one:
$ ng serve
Cannot read property 'config' of null
TypeError: Cannot read property 'config' of null
at Class.run (/project-path/node_modules/#angular/cli/tasks/serve.js:51:63)
at check_port_1.checkPort.then.port (/project-path/node_modules/#angular/cli/commands/serve.js:123:26)
at process._tickCallback (internal/process/next_tick.js:103:7)
I confused, because it worked perfectly on Mac.

I've found also answer npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for fsevents#1.0.14 it partly describes the messages, but it doesn't help me with my project running. (It can't be started any way).

Answer 1

To make my project runnable on Ubuntu I need a missed file on Mac (it seems mac does not need one) - .angular-cli.json:
{
"name": "angular4-in60-minutes",
"version": "0.0.0",
"license": "MIT",
"scripts": {
"ng": "ng",
"start": "ng serve",
"build": "ng build",
"test": "ng test",
"lint": "ng lint",
"e2e": "ng e2e"
},
"private": true,
"dependencies": {
"#angular/animations": "^5.0.1",

},

"protractor": "~5.1.2",

"tslint": "~5.7.0",
"typescript": "~2.4.2"
}
}
After adding this file my project can be started correctly. But issue with warnings present anyway
