Shinyapps.io发布问题:缺少网络快照依赖库"PhantomJS“

Question

当我将我的应用程序发布到shinyapps.io时，我发现了以下问题：

• PhantomJS
• 文件(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.

在本地闪亮的服务器上安装PhantomJS之后，我可以成功地创建PDF，但是，我不知道如何在shinyapps.io上解决它。
