有什么想法吗？Rails 3.2.2应用程序

Answer 1

可能是安装了多个版本的readline.

请尝试以下方法:

brew link readline --force

Answer 2

我几天前就有这个.您可以尝试重新安装/重新编译您的ruby.在我的情况下,从El Capitan更新到Sierra时出现了问题

所以取决于你的经理:

RVM

rvm reinstall 2.3.0

Rbenv

rbenv uninstall 2.3.0
rbenv install 2.3.0

ASDF

asdf uninstall ruby 2.3.0
asdf install ruby 2.3.0

Answer 3

在其他地方寻找,没有一个重新连接选项有效.有人建议重做rvm安装(看起来很麻烦).但是,只需在Gemfile中添加readline就可以了:

gem 'rb-readline'

Answer 4

这是因为安装了多个版本的readline(可能是因为你brew update最近运行过).罗恩说的是对的.您可以通过运行brew link readline或修复它brew link readline --force.

如果它仍然不起作用,找到哪个readline并移动到readline文件夹然后删除您不需要的版本(或通过运行brew update安装的版本).然后又跑brew link readline了.

Answer 5

对于我在 macOS sierra 上，brew link readline或者brew link readline --force不起作用，我brew update最近跑了。但是rails console在我执行以下操作后确实有效：

rvm reinstall 2.3.1
