我正在尝试使用RVM安装Ruby。我一直在关注Installfest guide over at RailsBridge。
到目前为止，我已经安装了RVM（curl -L get.rvm.io | bash -s stable），并将RVM配置为使用Homebrew（rvm autolibs homebrew）。当我在Terminal中输入rvm install ruby时，我得到以下输出：

ruby-2.5.1 - #removing src/ruby-2.5.1..
Searching for binary rubies, this might take some time.
No binary rubies available for: osx/10.13/x86_64/ruby-2.5.1.
Continuing with compilation. Please read 'rvm help mount' to get more information on binary rubies.
Checking requirements for osx_brew.
Certificates bundle '/usr/local/etc/[email protected]/cert.pem' is already up to date.
Requirements installation successful.

There has been an error while running make. Halting the installation.

我打开/Users/jules/. rvm/log/1530823409_ruby-2.5.1/make. log试图取得进展，但我无法从文件中收集任何意义。我已经把下面的内容贴上去了：
