Question

当我将应用程序发布到Shinyapps.io时，遇到了以下问题：

PhantomJS
file（con，“ rb”）：无法打开连接

输出pdf文件中的完整日志：

PhantomJS not found. You can install it with webshot::install phantomjs(). If it is installed, please make sure the phantomjs executable can be found via the PATH variable.

在我的本地Shiny服务器上安装PhantomJS之后，我可以成功创建PDF，但是，我不知道如何在Shinyapps.io上解决它。
