gemeventmachine致命错误：找不到“openssl / ssl.h”文件

刚安装了El Capitan，不能安装gemeventmachine 1.0.7 。 openssl在1.0.2a-1 。 试图使用--with-ssl-dir但似乎被忽略。

也报告给他们的github回购 。

任何build议真的很感激。 谢谢。

你也可以像这样设置捆绑器，但我认为这是肤浅的 

 bundle config build.eventmachine --with-cppflags=-I/usr/local/opt/openssl/include

使用捆绑器和自制软件时： 

 $ bundle config build.eventmachine --with-cppflags=-I$(brew --prefix openssl)/include $ bundle install 
 brew link --force openssl

然后： 

 gem install eventmachine

它也修复：

  • gem安装taks
  • 捆绑安装
  • 耙和铁轨任务

PS可能你需要删除并再次运行brew install openssl

问题的发生是因为苹果已经从OSX中删除了openssl（在El Captain版本中） 

 gem pristine eventmachine -- --with-cppflags=-I/usr/local/opt/openssl/include

原始删除旧的gem，并重新编译它。

cpp标志选项允许编译器findopenssl头文件。

您也可以添加该版本，如果你喜欢： 

 gem pristine eventmachine -v '1.0.4' -- --with-cppflags=-I/usr/local/opt/openssl/include

如果您将EventMachine作为另一个gem的依赖项安装，请确保在手动安装gem时指定正确的版本： 

 gem install eventmachine -v 1.0.5 -- --with-cppflags=-I$(brew --prefix openssl)/include

然后你可以安装你最初试图安装的gem： 

 gem install mailcatcher

我正在尝试安装v 1.0.3，这为我工作。 

 gem install eventmachine -v '1.0.3' -- --with-cppflags=-I/usr/local/opt/openssl/include

这些讨论非常有帮助。 https://github.com/eventmachine/eventmachine/issues/602

另一种方法是为整个用户configuration文件添加一个bundler config条目，如下所示： 

 cd ~ bundle config build.eventmachine --with-cppflags=-I$(brew --prefix openssl)/include

它将在您的主目录中创build一个.bundle / config文件，然后在您运行bundle install时将其用于所有项目。

这解决了我的问题： 

 PKG_CONFIG_PATH="$(brew --prefix openssl)/lib/pkgconfig" gem install eventmachine -v "1.0.8"
