我是网络开发和学习自学指南(odin项目)的新手。我刚刚开始安装我编程所需的所有不同工具,但遇到了问题。在Heroku部署的rails上设置ruby时,我收到语法错误。我正在按照指南http://goo.gl/v2LcbU进行操作,当我尝试执行步骤7.2(捆绑安装 - 没有生产)时,我收到语法错误。我运行ruby -c Gemfile
,错误显示Gemfile:37: syntax error, unexpected keyword_do, expecting $end
。
我已经尝试了一些事情,但我很困惑,不知道它试图说的是第37行的错误。如果你看看我链接的指南,它就是替换了一些Gemfile,这就是我的Gemfile看起来导致错误而不允许我bundle install --without production
。
的Gemfile http://i.imgur.com/IIjvhwM.png 我正在关联它的图像,因为我还不确定如何正确链接文件,抱歉。

这是无效的:
group
:doc do
# bundle exec rake doc:rails generates the API under doc/api.
gem 'sdoc', require: false
end
group
是一个被调用的方法,:doc
是一个参数,而do...end
块就是一个块。在Ruby中,第一个方法参数需要紧跟方法名称。你的小组看起来应该更像这样:
group :doc do
# bundle exec rake doc:rails generates the API under doc/api.
gem 'sdoc', require: false
end

您可以通过运行rails standard命令查看其他示例,如下所示:
rails new apptest
它将自动生成许多文件,包括Gemfile,在底部,你会看到如下内容:
group :development, :test do
gem 'byebug'
gem 'web-console', '~> 2.0'
gem 'spring'
gem 'rspec-rails'
gem 'capybara'
end
从这里学习,添加自己的宝石,享受rails :)。
