構建后空白頁ionic2

Question

通過以下命令：

ionic platform add android
ionic build android

我添加了平台和內置的APK文件，但在手機上運行該應用程序時卻遇到了黑屏。 軟件可在ionic serve正常運行，調試時沒有任何錯誤。 我也對ionic的建議應用程序有疑問

ionic start --v2 myApp sidemenu 

預先感謝您的幫助！

Answer 1

將此首選項添加到項目根目錄的“ config.xml”文件中：

<preference name="ShowSplashScreenSpinner" value="false" />
<preference name="SplashScreen" value="screen" />
<preference name="SplashScreenDelay" value="20000" />
<preference name="FadeSplashScreen" value="true" />
<preference name="FadeSplashScreenDuration" value="300" />
<preference name="SplashScreenBackgroundColor" value="false" />

Answer 2

我將確保您具有npm和node的最新版本。

然后確保您擁有最新版本的Ionic（2.2）

為此，您應該更新package.json文件..

"dependencies": {
"@angular/common": "2.4.8",
    "@angular/compiler": "2.4.8",
    "@angular/compiler-cli": "2.4.8",
    "@angular/core": "2.4.8",
    "@angular/forms": "2.4.8",
    "@angular/http": "2.4.8",
    "@angular/platform-browser": "2.4.8",
    "@angular/platform-browser-dynamic": "2.4.8",
    "@angular/platform-server": "2.4.8",
    "@ionic/storage": "2.0.0",
    "ionic-angular": "2.2.0",
    "ionic-native": "2.4.1",
    "ionicons": "3.0.0",
    "rxjs": "5.0.1",
    "sw-toolbox": "3.4.0",
    "zone.js": "0.7.2"
},
"devDependencies": {
    "@ionic/app-scripts": "1.1.4",
    "typescript": "2.0.9"
}

然后刪除您的node_modules目錄，然后運行：

npm install（或者sudo npm install）

這應該會更新所有內容，並有望解決問題
