我无法安装 eventmachine

好吧，我知道这个问题已经被问了很多，但到目前为止我没有找到对我有帮助的解决方案。所以我发布在这里作为最后的手段。

我使用 windows 8 x64 使用ruby 2.0.0p195 (x64)(通过适用于 Windows 的 Ruby Installer 和适当的 Devkit 安装)

所以错误是

    Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension

我尝试过的事情将 gem "eventmachine", "~> 1.0.3" 或 gem "eventmachine", "~> 1.0.0. beta.4.1" 在我的 gemfile 中，并从 gemfile.lock 中删除/修改 eventmachine 制作一个新的 testapp 并在那里安装 Eventmachine(失败)

我怀疑的事情 我追踪了 eventmachine 的依赖项(可以在 Rubygems 上找到)，我发现我无法安装 bluecloth两者都没有(显示更大的日志错误)，我也无法安装 tidy-ext (bluecloth depencency) 所以我认为它可能有一些相关性，也不能安装 thin

任何信息只要问

先谢谢大家!!

最佳答案

我可以安装它，执行以下步骤:

1) 尝试正常安装:

gem install eventmachine

它获取了 gem 的 1.0.3 版本，但由于变量声明冲突导致 make 失败

2) 编辑文件:

c:\Ruby200-x64\lib\ruby\gems\2.0.0\gems\eventmachine-1.0.3\ext\project.h

并注释了第97行

//typedef int pid_t;

要获得更稳健的更正，请在此处查看解决方案 https://github.com/eventmachine/eventmachine/pull/450/files

3) 然后，我打开命令提示符，然后转到 gem 文件夹

c:\Ruby200-x64\lib\ruby\gems\2.0.0\gems\eventmachine-1.0.3

然后运行:

gem build eventmachine.gemspec

您需要在 PATH 中使用 git.exe 位置安装 git 才能工作(例如 C:\Users\YourUsername\AppData\Local\GitHub\PORTAB~1\bin)。

4) 它在文件夹中生成了一个 eventmachine.gem 文件...所以我将一个文件复制到 c:\tmp 文件夹，然后转到该文件夹​​并从那里输入:

gem install eventmachine-1.0.3.gem --local

安装成功!
