尝试执行命令后,这是我的错误屏幕.我试图卸载并重新安装readline,但没有帮助.我只是学习rails并且不会100％知道我在做什么(只是按照指南)所以这种类型的错误超出了我的理解.谢谢！
解决方法
可能不相关,但我今天也遇到了同样的事情.
今天早上我有一个功能齐全的Ruby 2.3.1工作正常.就我而言,Ruby是由ruby-build编译和安装的,由rbenv管理.
今天有一次我更新了Homebrew
brew cleanup --prune=30 brew update brew upgrade
其中一个升级的公式是readline 7.0：
$brew info readline ... /usr/local/Cellar/readline/7.0 (45 files,2M) Poured from bottle on 2016-10-05 at 08:09:22
不久之后我发现我对Ruby的readline支持已经彻底破解了.我看到的错误和你的一样：
/Users/mbrictson/.rbenv/versions/2.3.1/lib/ruby/gems/2.3.0/gems/pry-0.10.4/lib/pry/config/default.rb:151:in `require': dlopen(/Users/mbrictson/.rbenv/versions/2.3.1/lib/ruby/2.3.0/x86_64-darwin15/readline.bundle,9): Library not loaded: /usr/local/opt/readline/lib/libreadline.6.dylib (LoadError) Referenced from: /Users/mbrictson/.rbenv/versions/2.3.1/lib/ruby/2.3.0/x86_64-darwin15/readline.bundle Reason: image not found - /Users/mbrictson/.rbenv/versions/2.3.1/lib/ruby/2.3.0/x86_64-darwin15/readline.bundle from /Users/mbrictson/.rbenv/versions/2.3.1/lib/ruby/gems/2.3.0/gems/pry-0.10.4/lib/pry/config/default.rb:151:in `lazy_readline'
rm -rf ~/.rbenv/versions/2.3.1 rbenv install 2.3.1
我知道你使用的是rvm而不是rbenv,但也许你的情况下的解决方案是类似的：删除你的Ruby安装并使用rvm重新安装它.
