我正在使用Ionic 2的Ionic本机代码推送库。当我使用codepush部署应用程序时，应用程序（在Android上）下载更新但在安装时失败。导致问题的原因通常是什么？＃34;无法计算包的散列＆＃34;？
以下是我的日志：
[CodePush] Installing update

这是我在主ts文件中的代码：
constructor(public plt: Platform, private codePush: CodePush) {
if (this.plt.is('cordova')) {
// Don't run codepush in browser.
this.plt.ready().then((readySource) => {
const downloadProgress = (progress) => { console.log(`Downloaded ${progress.receivedBytes} of ${progress.totalBytes}`); }
this.codePush.sync({}, downloadProgress).subscribe((syncStatus) => console.log(syncStatus));
});
}
}
