ruby – 不能在OS X El Capitan上安装thrift gem

尝试在OSX El Capitan升级后安装thift gem：

$gem install thrift
    Building native extensions.  This Could take a while...
    ERROR:  Error installing thrift:
        ERROR: Failed to build gem native extension.

        /Users/foo/.rvm/rubies/ruby-2.1.4/bin/ruby -r ./siteconf20160402-32256-7dzqel.rb extconf.rb

        rb_exc_raise(get_protocol_exception(INT2FIX(-1),rb_str_new2(buf)));
                                            ^~~~~~~~~~~

汇编失败
compact_protocol.c：442：41：错误：移动负号码值未定义[-Werror,-Wshift-negative-value]

解决方法

我有一个解决方案给你！希望.

有一天有同样的问题.

问题在于El Capitan捆绑的clang编译器.我确定它拧紧了其他问题,但这是一个问题,我有很多问题.

尝试运行以下命令,让我知道它是怎么回事！

gem install thrift -- --with-cppflags=\"-D_FORTIFY_SOURCE=0 -Wno-shift-negative-value\"
