fedena安装错误（ruby on rails）

Question

我是ruby和rails的新手。我正在尝试安装fedena项目。但是在执行rdoc db:create我收到的错误就像failed to allocate memoryls/generators/rspec_controller/templates/helper_spec.rb 。 我的系统中已经有4GB的ram，并且3.5 gb是免费的。这需要多少内存？它是封装错误吗？ 我正在使用以下铁轨红宝石版本

Rail: Rails 2.3.5
Ruby:ruby 2.1.0
rake, version 10.1.1
rdoc-4.1.0

我认为您使用的是错误版本的Ruby，因为它们在文档中指定了它们。 使用rails作为

Rails 2.3.5（注意：版本应为2.3.5），

红宝石

ruby-1.8.7-p302

在Windows中，他们正在使用这个特定版本的ruby
