我正在尝试将应用程序部署到heroku。当我在 gemfile 中有 gem 'rootapp-rinruby' 时，它部署得很好，但是当我使用 gem 'rinruby' 时，会出现以下输出。
我一直在尝试进行一些调试，包括:
- 在
生产.rb中设置config.assets.compile = true，并通过建议的方法here进行设置 - 正在运行
bundle exec rake -P(请参阅下面第二个代码片段中的输出) - 更新 gem
我真的被困住了。
我确实注意到 ruby/2.5.0 频繁出现在下面的错误消息中，这让我很怀疑，因为 ruby -v 返回 ruby 2.5.1p57 (2018-03-29 修订版 63029)[x86_64-darwin17] 并且我在 gemfile 中有 ruby '2.5.1' 。但这可能与此无关

最佳答案
当 Rails 需要 rinruby gem 时，它将调用 RinRuby.new (请参阅 here )，它最终会尝试运行 R 命令，请参阅 here 。使用 rootapp-rinruby gem 时不会引发错误，因为在需要 gem/文件时不会调用 RinRuby.new。
但是，当使用 rootapp-rinruby gem 并调用 RinRuby.new 时，会出现类似的错误。
解决这个问题的方法是在 Heroku 上安装 R 库。我建议检查一下如何安装它。一些快速的 Google 结果:
- https://medium.com/@DaveQuartey/how-i-installed-r-on-heroku-ff8286233d2c
- https://elements.heroku.com/buildpacks/dpmccabe/heroku-buildpack-r
- https://www.r-bloggers.com/running-an-r-script-on-heroku/
对于 rinruby，您还必须确保 heroku R 构建包在安装 Ruby/bundler 构建包
