ruby-on-rails - 在 Windows 8 上安装 eventmachine

Question

我正在尝试安装 eventmachine，以便可以运行此程序https://github.com/alexagranov/earnings_date_finder 以查看它的作用。

我收到此错误：

C:\Users\Dakota\Downloads\rails\rails_apps\earnings>ruby script/rails
Could not find eventmachine-0.12.10 in any of the sources
Run `bundle install` to install missing gems.

当我运行“捆绑安装”时，我得到了这个：

An error occurred while installing eventmachine (0.12.10), and Bundler cannot

Make sure that `gem install eventmachine -v '0.12.10'` succeeds before bundling.

我尝试了许多不同的方法来安装 eventmachine，但每种方法都会给我同样的错误。

对于记录'gem install eventmachine --pre'给了我这个错误：

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 conflit 而在 make 中失败

2）编辑文件：

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

并评论了第 97 行

//typedef int pid_t;

3）然后，我打开了命令提示符，然后转到 gem 文件夹

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

并运行：

gem build eventmachine.gemspec

4) 它在文件夹上生成了一个 eventmachine.gem 文件...所以我将一个文件复制到 ac:\tmp 文件夹，然后转到该文件夹，然后从那里输入：

gem install eventmachine-1.0.3.gem --local

并且安装成功！

按照费拉的步骤。是的，它现在确实安装了消息

Successfully installed eventmachine-1.0.3
1 gem installed

但不可用。

在 \lib\ruby\gems\2.0.0\gems\eventmachine-1.0.3\ext 中，mkmf.log 中有一个错误，实际上没有构建任何内容

package configuration for openssl is not found
have_library: checking for main() in -lssl... -------------------- no

通过 Reddit 找到你！

尝试使用预编译的eventmachine gem

gem install eventmachine --pre

您遇到此问题是因为 eventmachine gem（或其依赖项之一）是用 C 编写的，需要由本地可用的 C 编译器（LLVM、GCC 等）编译。

如果--pre在 gemfile 中包含该标志后仍然出现此问题，我将卸载所有本地 eventmachine 版本并查看以下链接：

希望这可以帮助！
