Ruby使用rbenv在OSX Lion上失败

Question

我一直在尝试在我的Lion机器上安装Ruby(OSX 10.7.3).

我安装了rbenv和ruby-build,我试图在我的机器上获得1.9.2-p290.以下是安装失败的输出:

$ rbenv install 1.9.2-p290

我试图解决这个问题,但到目前为止我还没有提出任何解决方案:

$ which gcc
/usr/bin/gcc
$ gcc
i686-apple-darwin11-llvm-gcc-4.2: no input files
$ ruby-build
ruby-build 20120216
usage: ruby-build [-v|--verbose] definition prefix
       ruby-build --definitions

任何帮助将不胜感激!

作为旁注,我已尝试在此处发布其他类似的建议,但没有一个对我有用.

根据ruby-build 问题#130,当前的解决方法是:

env CC=/usr/bin/gcc rbenv install 1.9.3-p125

我刚刚在一个系统上测试了这个:

• OS X 10.7.3
• Xcode 4.3.1
• 安装Xcode的命令行工具(通过Xcode>首选项>下载)
• ruby-build @ fbfa944
• rbenv @ 975b45d

此外,挂起请求#137旨在一劳永逸地解决这个问题.

FWIW,许多人正在摆脱Xcode 4.3.x的构建链问题.如果你升级到新的工具链直到集体尘埃落定,那么任何系统都会出现一些不稳定因素.

似乎有两个或三个堆栈溢出问题与使用通过/ 在Mac OS X上rbenv安装ruby的错误有关,并且我已经尝试了很多这些解决方案而没有运气.设置编译器并通过自制软件安装apple gcc42编译器没有帮助(并且- 没有运气)因此我不确定它们是否必要.我正在使用经理,因此在尝试安装时这对我有用1.9.xhomebrewrbenvbrew install apple-gcc42CC=/usr/bin/gccrbenv1.9.3-p385

问题在于日志显示的readline:

readline.c: In function ‘username_completion_proc_call’:
readline.c:1499: error: ‘username_completion_function’ undeclared (first use in this function)
readline.c:1499: error: (Each undeclared identifier is reported only once
readline.c:1499: error: for each function it appears in.)

因此,在专门查找该错误后,我找到了解决方案:

解:

brew install readline
CONFIGURE_OPTS="--with-readline-dir=$(brew --prefix readline)" rbenv install 1.9.3-p385

您可以rbenv install 1.9.3-p385将命令的一部分与最新版本或您尝试安装的版本匹配.在此博客上找到了该说明.

这可能是根据您需要的级别而不是您直接询问的级别来回答的，但是：您是否考虑过简单地使用 macports（请参阅 macports.org）或 brew 作为安装 ruby​​ 1.9 的方式？它效果很好，而且省力得多。
