应用程序无法在 R Shiny 中启动（以代码 1 退出）

Question

我在部署闪亮应用程序时收到错误“应用程序无法启动（以代码 1 退出）”。

\n\n

\n错误消息已附加。在控制台中，部署后我收到以下消息：

\n\n

Preparing to deploy application...DONE\nUploading bundle for application: 365672...DONE\nDeploying bundle: 1444503 for application: 365672 ...\nWaiting for task: 533366947\nbuilding: Parsing manifest\nbuilding: Building image: 1457861\nbuilding: Fetching packages\nbuilding: Installing packages\nbuilding: Installing files\nbuilding: Pushing image: 1457861\ndeploying: Starting instances\nrollforward: Activating new instances\nsuccess: Stopping old instances\nApplication successfully deployed to \nhttps://programmingrpython.shinyapps.io/shinyapp/\n

\n\n

该应用程序在本地运行。但是，当我运行应用程序时，我在控制台中收到这些消息：

\n\n

我使用的软件包是：

\n\n

library(shiny)\nlibrary(plotly)\nlibrary(data.table)\n

\n\n

是因为警告信息吗？\n我已关注https://github.com/ropensci/plotly/issues/985但我仍然收到此警告。

任何人都可以建议为什么部署后显示错误消息吗？

setwd()您的应用程序开头有一个函数吗？您需要在部署应用程序之前对其进行评论或删除。我总是#comment它。

注释代码中指定计算机目录本地路径的任何部分
