Shinyapps.io 发布问题：缺少 webshot 依赖库“PhantomJS”

Question

当我将我的应用发布到 shinyapps.io 时，我遇到了以下问题：

• 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.

在本地 Shiny 服务器上安装 PhantomJS 后，我可以成功创建 PDF，但是，我不知道如何在 shinyapps.io 上解决它。
