如何使用 rails 控制台命令更正错误？

Question

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

[myrailsapp (master)]$ rails c

我进行了网络搜索，但没有找到针对此类错误的任何解决方案。

Answer 1

编辑：好的运行这个

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

从旧引用中删除目录

Answer 2

brew rm -f readline

brew install readline

brew link readline --force

参考link：rails console doesn't load due to libreadline

Answer 3

在我的例子中，使用 rvm 重新安装修复了错误

rvm reinstall 2.3.0
