我正在为支持1.7.4的rails项目设置环境。我正在使用rvm，因此在rvm本身的帮助下继续在Mac 10.12.6（Macbook Air）上安装Jruby 1.7.4。
rvm install 1.7.4
以下是我的输出
Searching for binary rubies, this might take some time.
No binary rubies available for: osx/10.12/x86_64/jruby-1.7.4.
Continuing with compilation. Please read 'rvm help mount' to get more information on binary rubies.
Checking requirements for osx.

jruby-1.7.4 - #ant jar.......
Error running '__rvm_ant jar',
please read /Users/solid/.rvm/log/1506220984_jruby-1.7.4/ant.jar.log
如果我尝试安装任何其他版本的ruby，例如2.4.1或2.0.0，它可以工作。 以下是ant.jar.log文件的内容
