无法在RokuRuby上运行R on Heroku

R在我的Rails 4.2.6应用程序的开发中运行正常，但我无法使用RinRuby gem（2.0.3）在Heroku上运行它。 Heroku的拒绝与以下错误企图推（日志中的相关部分）：无法在RokuRuby上运行R on Heroku

ensure you can run `$ bundle exec rake -P` against your app 
and using the production group of your Gemfile. 
rake aborted!

Gem Load Error is: No such file or directory - R 
ruby_compile:15:in `<main>' 
    !  Push rejected, failed to compile Ruby app. 
    !  Push failed

我没有安装RinRuby之前部署到Heroku的问题。我可以成功运行

bundle exec rake -P command

针对应用程序。我也尝试过放置

config.assets.compile =true

在生产环境中，但是没有解决问题。

不知道语法错误是怎么回事;难倒了RinRuby加载错误。在生产中部署R，我在根目录下面的文件：

.buildpacks：

http://github.com/virtualstaticvoid/heroku-buildpack-r.git#cedar-14-chroot 
https://github.com/heroku/heroku-buildpack-ruby.git

init.r：

install.packages("ggplot2", dependencies = TRUE)

虽然研究，我发现了一个类似的，但没有答案发帖：Install error of Rinruby on Heroku

我遗失了什么？我该如何解决？更多详细信息...这里是宝石文件：

我成功地在Heroku for my Rails应用上安装了R。在努力帮助别人谁可能需要此信息，下面是我解决问题的步骤：

卸载RinRuby宝石，并安装rootapp-rinruby（https://rubygems.org/gems/rootapp-rinruby），较新叉RinRuby宝石。

体改的int.r文件：

my_packages = c("ggplot2") 


install_if_missing = function(p) { 
    if (p %in% rownames(installed.packages()) == FALSE) { 
    install.packages(p, dependencies = TRUE) 
    } 
    else { 
    cat(paste("Skipping already installed package:", p, "\n")) 
    } 
} 
invisible(sapply(my_packages, install_if_missing))

创建一个名为1,1'-版本，并把它放在根目录下，内容如下：

3.4.0
将此R buildpack（http://github.com/virtualstaticvoid/heroku-buildpack-r.git#cedar-14-chroot）添加到Heroku

现在，当我推开，Heroku的日志报告....

R 3.4.0 successfully installed (with init)

我希望这个信息可以帮助别人。祝你好运！
