uni-app 热更新失败.以前成功的

示例代码：

uni.downloadFile({  
    url: res.data.wgtUrl,  
    success: (downloadResult) => {  
        console.log(123)  
        console.log(downloadResult)  
        if (downloadResult.statusCode === 200) {  
            console.log(downloadResult)  
            console.log(downloadResult.tempFilePath)  
            plus.runtime.install(downloadResult.tempFilePath, {  
                force: false  
            }, function() {  
                console.log('install success...');  
                plus.runtime.restart();  
            }, function(e) {  
                console.log('install fail...' +JSON.stringify(e));  
            })  
        }  
    }  
});

操作步骤：
