ruby 2.3.1缺少的库

Question

目前正试图在我的终端(macOS塞拉利昂)上使用rvm安装Ruby2.3.1，但是遇到了这个错误

Ruby2.3.1缺少的库: /Users/travis/.rvm/rubies/ruby-2.3.1/lib/libruby.2.3.0.dylib，/usr/local/opt/gdbm/lib/libgdbm.4.dylib。安装库请参阅系统手册。

此错误类似于堆栈溢出时的another question，但那里的解决方案对我不起作用。我是Ruby的新手，所以任何帮助都是非常感谢的。

顺便说一下，这是终端的全部输出。

Answer 1

首先，您安装了Xcode吗？如果没有，您可以在这里获得命令行工具：http://railsapps.github.io/xcode-command-line-tools.html

它似乎是说，您有Xcode-beta，但删除了它，现在它没有办法正确安装。命令行工具应该足够好。

我也有同样的错误，但是安装成功了。

但是您的消息看起来非常明确: /bin/sh: /Applications/Xcode-beta:没有这样的文件或目录，您有这个目录吗？
