我在安装Shinyrgl软件包时遇到问题。该软件包已安装，但未正确安装

Question

这是我得到的错误。

c("Loading required package: -", "Loading required package: shiny", "Loading required package: incubator")
Failed with error:  ‘'package' must be of length 1’
In addition: Warning message:
In if (!loaded) { :
  the condition has length > 1 and only the first element will be used
Error in parse_repo_spec(repo) : 
  Invalid git repo specification: 'shiny-incubator'

我想加载/打开一个R文件，但需要先安装所有软件包。问题在于此错误不允许我打开R文件。
