我想在 heroku 服务器上运行一个 ruby​​ 脚本。问题是当我在 Heroku 上运行脚本时，它似乎看不到任何宝石！这是我刚刚创建的示例测试情况。

我在 test.rb 文件中有一个简单的 Ruby 脚本：

require 'rubygems'
require 'mechanize'

puts "Success!"

我也有一个 Gemfile：

source :rubygems
ruby '1.8.7'
gem 'mechanize'

一切都在我的本地机器上运行

~/Ruby/test % ruby test.rb
Success!

当我把它推到heroku时它看起来很好

~/Ruby/test % git push heroku master
Enter passphrase for key '/home/sadie/.ssh/id_rsa': 
Counting objects: 9, done.
Compressing objects: 100% (7/7), done.
Writing objects: 100% (9/9), 1.02 KiB, done.
Total 9 (delta 1), reused 0 (delta 0)

但运行脚本失败：

    from /app/vendor/ruby-1.8.7/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:36:in `require'
    from test.rb:2

提前致谢！

尝试运行：

heroku run bundle exec ruby test.rb

你指定了一个特定的 ruby​​ 版本，所以你需要用它来执行它。
