RVM不会在雪豹上安装Ruby 1.9.2：’运行错误’make’

rvm install 1.9.2

我得到以下内容：

ERROR: Error running 'make ',please read /Users/mary/.rvm/log/ruby-1.9.2-p180/make.log
ERROR: There has been an error while running make. Halting the installation.

所以,我查看了make.log.结尾如下：

readline.c: In function ‘username_completion_proc_call’:
readline.c:1386: error: ‘username_completion_function’ undeclared (first use in this 
function)

readline.c:1386: error: (Each undeclared identifier is reported only once
readline.c:1386: error: for each function it appears in.)
make[1]: *** [readline.o] Error 1
make: *** [mkmain.sh] Error 1

我已经咨询了这个问题的其他答案,并做了一切建议：

>安装了XCode.
> .bash_profile的结尾添加了以下行：

[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm"

我已经尝试更新readline,但无论如何,我继续收到有关运行’make’的错误消息.

rvm信息的输出如下：
