Gem eventmachine致命错误:'openssl/ssl.h'文件未找到

刚安装El Capitan，不能安装gem eventmachine 1.0.7。Openssl的版本是1.0.2a-1。尝试使用——with-ssl-dir，但似乎被忽略了。

报告到他们的github回购以及。

任何建议都非常感谢。谢谢。

当前回答

如果你将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

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

你也可以这样设置捆绑器，但我认为这是肤浅的

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

这为我解决了问题:

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

当使用bundler和homebrew时:

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

这对我很管用

    gem install eventmachine -v '1.0.7' -- --debug --backtrace --with-cppflags=-I/usr/local/opt/openssl/include --with-ldflags=-L/usr/local/opt/openssl/lib
    Building native extensions with: '--debug --backtrace --with-cppflags=-I/usr/local/opt/openssl/include --with-ldflags=-L/usr/local/opt/openssl/lib'

注意:在我能够成功安装这个宝石之前，我必须做一些事情。这些可能适用于你，所以在这里列出它们-

1.)退出公司vpn 或者你可能不得不打开代理设置

2)。PKG_CONFIG_PATH设置为-

echo $PKG_CONFIG_PATH
/usr/local/opt/openssl/lib/pkgconfig

3.)必须在bash_profile中添加以下到$PATH(在我的情况下~/.zshrc)

export PATH="/usr/local/opt/openssl/bin:$PATH"

4)。另外请注意，与我在这篇SO帖子中得到的一些答案相反，以及github-eventmachine上的这个线程，我无法安装eventmachine

在指定openssl位置时，/usr/local/opt/openssl/include似乎是正确的位置，而不是/usr/local/include。

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

质朴删除旧的宝石并重新编译它。

cpp flags选项允许编译器找到openssl头文件。

如果你喜欢抽象cpp标志参数，你可以这样做:

PKG_CONFIG_PATH="$(brew --prefix openssl)/lib/pkgconfig"

你也可以添加版本，如果你喜欢:

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