问题描述
当我尝试运行简单的 rails 命令时，例如:
When I try to run even simple rails commands such as:
rails -h
几秒钟后我收到一个弹出错误消息:
I get a popup error after a few seconds that says:
ruby.exe - 无法找到组件
此应用程序启动失败因为 msvcrt-ruby18.dll 不是成立.重新安装应用程序可能会解决问题.
This application has failed to start because msvcrt-ruby18.dll was not found. Re-installing the application may fix the problem.
我正在跑步:
- Windows XP(是的，我知道我应该在 Windows 机器上尝试 ruby).
- Ruby 1.9.1p378 [i386-mingw32].
- 已将我所有的 gem 更新到最新版本(截至 2010 年 7 月 14 日).
有什么方法可以测试导致此错误的原因吗?有谁知道这意味着什么?
Is there a way I can test what is making this error? Does anyone know what it could mean?
我发现在我的 ruby19/bin 文件夹中有 msvcrt-ruby191.dll 但没有 msvcrt-ruby18.dll任何地方.如果我使用的是 ruby 1.9，它为什么还要寻找这个?
I have found that in my ruby19/bin folder there is msvcrt-ruby191.dll but there is no msvcrt-ruby18.dll anywhere. Why would it be looking for this anyway if I'm using ruby 1.9?
推荐答案
Mongrel 1.1.5 的当前发布版本与 Ruby 1.9 不兼容，运行时抛出此错误.这很容易解决 - 只需确保 Rubygems 是最新的:
The current release version 1.1.5 of Mongrel is incompatible with Ruby 1.9 and throws this error when it is run. It's easy to solve - just make sure Rubygems is up-to-date:
gem update --system
然后安装新的 Mongrel 预发布版本:
Then install the new pre-release version of Mongrel:
gem install mongrel --pre
或者，如果这不是由 Mongrel 引起的，您可以尝试安装 DevKit，然后试试这个:
gem install *gemname* --platform=ruby
这会强制使用 DevKit 从源代码编译扩展，并适用于我尝试过的大多数主要 gem.
This forces compilation of the extension from source using DevKit and works with most of the major gems I've tried.
