Question

当我在我的Rails应用程序的根目录中时，我可以成功执行rails server。但是，当我尝试rails console或rails c时，我收到以下错误。

[myrailsapp (master)]$ rails c

我已完成网络搜索，但我没有找到任何解决此类错误的方法。

Answer 1

brew rm -f readline

brew install readline

brew link readline --force

Answer 2

在我的情况下，使用rvm重新安装修复了错误

rvm reinstall 2.3.0

Answer 3

编辑：确定运行此

sudo install_name_tool -change libreadline.6.dylib 
/usr/local/opt/readline/lib/libreadline.6.dylib
/Users/myuserid/.rvm/rubies/ruby-2.3.0/lib/ruby/2.3.0/x86_64-darwin15/readline.bundle

sudo install_name_tool -change libreadline.6.dylib 
/usr/local/opt/readline/lib/libreadline.6.dylib
/Users/myuserid/.rvm/rubies/ruby-2.3.0/ruby/2.3.0/x86_64-darwin15/readline.bundle
