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

刚刚安装了El Capitan而无法安装gem eventmachine 1.0.7。openssl在1.0.2a-1。尝试使用，--with-ssl-dir但似乎被忽略了。

也将其报告给他们的github仓库。

任何建议都非常感谢。谢谢。

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

您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

使用捆绑程序和自制软件时：

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

brew link --force openssl

然后：

gem install eventmachine

它还可以修复：

• 宝石安装包
• 捆绑安装
• 耙子和铁轨任务

PS可能您需要删除并brew install openssl再次运行

发生问题是因为Apple已从OSX中删除了openssl（在El Captain中构建）

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

原始删除旧宝石并将其重新编译。

cpp标志选项允许编译器找到openssl标头。

您还可以根据需要添加版本：

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

如果您要安装EventMachine作为另一个gem的依赖项，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，您可以安装最初尝试安装的gem：

gem install mailcatcher

我正在尝试安装v 1.0.3，这对我有用。

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

一种替代方法是为整个用户个人资料添加捆绑程序配置条目，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建一个.bundle / config文件，然后在运行时将其用于所有项目中bundle install。

这为我解决了问题：

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

这对我有用-

    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

注意：-在我能够成功安装该gem之前，我必须做一些事情。这些可能对您适用，因此请在此处列出-

1.）退出企业VPN，否则您可能需要打开代理设置

2.）PKG_CONFIG_PATH设置为-

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

3.）必须在bash_profile的$ PATH中添加以下内容（在我的情况下为〜/ .zshrc）

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

4.）还请注意，与我在这篇SO帖子以及github-eventmachine上的该线程上获得的一些答案相反，我无法安装eventmachine

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