ruby-on-rails - gem rinruby 的 RubyOnRails 错误

我正在尝试使用 rinruby 2.0.3。

在我的 Gemfile 中:

gem 'rinruby', '~> 2.0.3'

当我执行 bundle install 时，我没有任何问题。但是当我执行时:

rake db:migrate

我有这个错误:

$ rake db:create
rake aborted!
Bundler::GemRequireError: There was an error while trying to load the gem 'rinruby'.
/home/jerviver21/workspace_upworkruby/blog1/config/application.rb:7:in `<top (required)>'

(See full trace by running task with --trace)

我使用的是 Ubuntu 14.04 和 postgreSQL 9.4.7

这是我的 Gemfile:

source 'https://rubygems.org'

#Buscar en rubygems.org las implementaciones que se necesiten
#Registro y autenticacion de usuarios
gem 'devise'

# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'

最佳答案

我刚刚测试了在 Ruby 2.4.0-dev 上安装 rinruby 2.0.3 gem。

起初，运行 require 'rinruby' 给了我一个关于没有安装 R 的错误。

所以我跟着 these instructions 在 Ubuntu 14.04 上安装 R

之后，需求成功。
