Question

我按照Deploying R shiny app as a standalone application中描述的步骤创建了一个示例Shiny应用程序。

我已经安装了＆＃34; RInno＆＃34;来自github的包（ficonsulting / RInno）。

在空R项目中，我执行了以下代码。

library(shiny)
library(RInno)

example_app(app_dir = "app") 

create_app(app_name = "myapp", app_dir = "app")
#The step above produces an error: 'write_json' is not an exported object from 'namespace:jsonlite'

compile_iss()

哪个失败并出现错误。如何解决这个问题？

Answer 1

我认为这个问题是由旧版本的jsonlite引起的。 RInno需要jsonlite＆gt; = 1.5。

创建包含在RInno包中的示例闪亮应用程序安装程序会产生与＆＃39;命名空间相关的错误：jsonlite＆＃39;
