My node.js version is v6.9.1

[zelongg]

I change the below
_getPage(pageIdx: number, loop = false: boolean) {
to

_getPage(pageIdx: number, loop: boolean = false) {

It still doesn't work.

Oh, it make the build error disappear. But when opening the android app, I got the below.

[zelongg]

Update:

I tried to delete node_modules and install everything again.
And it worked.

Here is my reference.
xotahal/react-native-material-ui#26

Plus, I also add the lines in 'ZhiHuDaily-React-Native/android/build.gradle'.

allprojects {
    repositories {
        mavenLocal()
        jcenter()
        maven {
            // All of React Native (JS, Android binaries) is installed from npm
            url "$rootDir/../node_modules/react-native/android"
        }
    }
}

My dev-os is Win-10, but seems like this project need dependency - fsevents which is on OSX.

so after "npm install" will post below warnings
"npm WARN optional SKIPPING OPTIONAL DEPENDENCY: [email protected] (node_modules\fsevents):
npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for [email protected]: wanted {"os":"darwin","arch":"any"} (current: {"os":"win32","arch":"x64"})"

[ScottYang36]

modify:
_getPage(pageIdx: number, loop = false: boolean) {
to
_getPage(pageIdx: number, loop: boolean = false) {

build failed solved.
