我正在使用 Windows，我刚刚运行了命令：

C:\Sites\cmply>gem install SystemTimer -v '1.2.3'

我得到了这个错误：

Temporarily enhancing PATH to include DevKit...
Building native extensions.  This could take a while...
ERROR:  Error installing SystemTimer:
        ERROR: Failed to build gem native extension.

        C:/RailsInstaller/Ruby1.9.3/bin/ruby.exe extconf.rb

system_timer_native.c: In function 'install_first_timer_and_save_original_configuration':

知道为什么吗？在此之前，我遇到了另一个可疑错误：

Gem files will remain installed in C:/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/SystemTimer-1.2.3 for inspection.
Results logged to C:/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/SystemTimer-1.2.3/ext/system_timer/gem_make.out
An error occured while installing SystemTimer (1.2.3), and Bundler cannot continue.
Make sure that `gem install SystemTimer -v '1.2.3'` succeeds before bundling.

在此之前，我遇到了另一个错误，似乎表明我的 Ruby 版本不同步：

C:\Sites\cmply>bundle update rake
Updating git://github.com/twitter/twitter-text-rb.git
Fetching source index for http://rubygems.org/
Bundler could not find compatible versions for gem "activesupport":
  In snapshot (Gemfile.lock):
    activesupport (3.2.3)

  In Gemfile:
    rails (= 3.1.3) x86-mingw32 depends on
      activesupport (= 3.1.3) x86-mingw32

Running `bundle update` will rebuild your snapshot from scratch, using only
the gems in your Gemfile, which may resolve the conflict.

那么这一切都源于我拥有一个不兼容的 ruby​​ 版本吗？这应该如何解决？

谢谢！

您无法使用 ruby​​ 1.9 安装 system_timer gem，但这不是错误，而是一项功能。这是完整的解释。

“system_timer 仅在您运行 Ruby 1.8 时才相关。如果您正在运行 Ruby 1.9，则不需要它”

如果您从 Ruby 1.8 切换到 1.9，只需删除 system_time gem 并更新处理超时的代码。

检查输出，它说您正在为 Ruby 1.9.3 构建包含 1.9.1 的包含文件。

看起来您的 Ruby 安装以某种方式损坏了。我会尝试重新安装 Ruby 1.9.3 并检查包含文件是否存在c:/RailsInstaller/Ruby1.9.3/include/ruby-1.9.3/于c:/RailsInstaller/Ruby1.9.3/include/ruby-1.9.1/.
