R Shiny中的应用程序无法启动（以代码1退出）

Question

在部署闪亮的应用程序时，出现错误“应用程序无法启动（代码1退出）”。

该错误消息已附加。在控制台中，部署后我收到以下消息：

Preparing to deploy application...DONE
Uploading bundle for application: 365672...DONE
Deploying bundle: 1444503 for application: 365672 ...

应用程序在本地运行。但是，运行应用程序时，我会在控制台中收到以下消息：

The following object is masked from ‘package:ggplot2’:

last_plot

The following object is masked from ‘package:stats’:

filter

The following object is masked from ‘package:graphics’:

layout

Warning in origRenderFunc() :

Warning in origRenderFunc() :
Ignoring explicitly provided widget ID "5298324e516f"; Shiny doesn't use them

我正在使用的软件包是：

library(shiny)
library(plotly)
library(data.table)

是因为警告消息吗？ 我已关注https://github.com/ropensci/plotly/issues/985，但仍收到此警告。

请问为什么部署后会显示错误消息？

Answer 1

我有同样的问题。我评论了创建应用程序并成功部署该应用程序的library(Shiny)行。

Answer 2

应用程序开头是否有setwd()功能？在部署应用程序之前，您需要评论或删除它。我总是#comment它。

注释代码的任何部分，这些部分在您的计算机目录中指定本地路径
