(修订)问题：
在我的OS X优胜美地(10.10.1)系统上安装美宝玛宝石是什么？我已经耗尽了一大堆(我有XCode工具,我有OpenSSL),但是在尝试构建本机扩展时仍然失败.
问题
在我的OS X系统上,当我做：
$gem install puma
我得到：
Building native extensions. This Could take a while... ERROR: Error installing puma: ERROR: Failed to build gem native extension. /Users/home/sandBox/usr/bin/ruby extconf.rb checking for SSL_CTX_new() in -lssl... no checking for SSL_CTX_new() in -lssleay32... no *** extconf.rb Failed *** Could not create Makefile due to some reason,probably lack of necessary libraries and/or headers.

Results logged to /Users/home/sandBox/usr/lib/ruby/gems/2.1.0/extensions/x86_64-darwin-14/2.1.0/puma-2.10.2/gem_make.out
环境
我怀疑gem安装无法找到SSL头和/或库.这是我的系统上的(注意〜/ sandBox / usr是我的“沙盒”目录,包含我的Ruby on Rails开发的所有可执行文件,库,标题等).请注意,“ssl.h”定义SSL_CTX_new()：
$which openssl ~/sandBox/usr/bin/openssl $openssl version OpenSSL 1.0.1j 15 Oct 2014 $openssl version -d OPENSSLDIR: "/Users/home/sandBox/usr/ssl" $find ~/sandBox/usr -name "*libssl*" -print ~/sandBox/usr/lib/libssl.a $find ~/sandBox/usr -name "*.h" -exec grep SSL_CTX_new {} /dev/null \; ~/sandBox/usr/include/openssl/ssl.h:SSL_CTX *SSL_CTX_new(const SSL_METHOD *meth);
另外,这里是如何编译ruby的. $INSTALL_DIR是〜/ home / sandBox：
./configure --prefix=$(INSTALL_DIR) --enable-shared --disable-install-doc --with-opt-dir=$(INSTALL_DIR) --with-openssl-dir=$(INSTALL_DIR)/bin; where INSTALL_DIR is ~/sandBox/usr.
问题
我只是想要一些构建过程的配置标志？我或多或少地尝试过一堆标志：
$gem install puma -- --with-openssl-dir=/Users/home/sandBox/usr/ssl $gem install puma -- --with-ssllib=/Users/home/sandBox/usr/lib/libssl.a $gem install puma -- --with-ssl=/Users/home/sandBox/usr/bin/openssl $gem install puma -- --with-ssl=/Users/home/sandBox/usr/bin $gem install puma -- --with-opt-dir=/Users/home/sandBox/usr
但是在每种情况下都有相同的错误.有人能告诉我我失踪了吗？
更多信息…
带有错误的mkmf.log文件看起来像这样(为了可读性而添加换行符)：
"clang -o conftest -I/Users/home/sandBox/usr/include/ruby-2.1.0/x86_64-darwin14.0 -I/Users/home/sandBox/usr/include/ruby-2.1.0/ruby/backward -I/Users/home/sandBox/usr/include/ruby-2.1.0 -I. -I/Users/home/sandBox/usr/include -D_XOPEN_SOURCE -D_DARWIN_C_SOURCE -D_DARWIN_UNLIMITED_SELECT -D_REENTRANT -O3 -fno-fast-math -ggdb3 -Wall -Wextra -Wno-unused-parameter -Wno-parentheses -Wno-long-long -Wno-missing-field-initializers -Wunused-variable -Wpointer-arith -Wwrite-strings -Wdeclaration-after-statement -Wshorten-64-to-32 -Wimplicit-function-declaration -Wdivision-by-zero -Wextra-tokens -fno-common -pipe conftest.c -L. -L/Users/home/sandBox/usr/lib -L/Users/home/sandBox/usr/lib -L. -fstack-protector -L/Users/home/sandBox/usr/lib -lruby.2.1.0 -lssl -lpthread -ldl -lobjc " conftest.c:13:57: error: use of undeclared identifier 'SSL_CTX_new' int t(void) { void ((*volatile p)()); p = (void ((*)()))SSL_CTX_new; return 0; }
当我浏览我的沙箱目录树时,唯一定义SSL_CTX_new的头文件是〜/ sandBox / include / openssl / ssl.h.看来这个文件没有包括在内,我目前还在为甚么而感到失望.
解决方法
对于那些遇到麻痹症和开漏症的人来说,特别是在Mac OS 10.11(El Capitan)上,添加一些标志可以节省您几个小时的心痛：
gem install puma -- --with-cppflags=-I/usr/local/opt/openssl/include --with-ldflags=-L/usr/local/opt/openssl/lib
