Question

eze@eze:~/Appp$ rbenv local
rbenv: no local version configured for this directory
eze@eze:~/Appp$ rbenv global
2.2.1
eze@eze:~/Appp$ rbenv versions
* 2.2.1 (set by /home/eze/.rbenv/version)

我最近用rbenv卸载并重新安装了ruby，但是当我再次安装时，我意识到除了rails控制台之外一切正常，这是输出错误

<强>解决方案：

gem update --system。您似乎没有安装更新版本的rubygems以配合您的新版Ruby。

对不起，我花了很长时间才找到适合你的解决方案，现在看起来更加明显。 :)

原始答案：

您是否确保使用rbenv正确设置了全局（或可能是本地的，如果您有一套）Ruby版本？您是否尝试过rbenv rehash。

由于某些原因，你似乎错过了Ruby标准库中的Set模块 - 但是因为我认为它是标准库的一部分并且应该存在，除非你的Ruby安装以某种方式被破坏，这让我想知道是否由rbenv安装的垫片可能指向错误的位置。我相信rbenv rehash应该解决这个问题，如果这是原因。

否则，您可以提供有关您的环境的更多信息吗？ <输出

rbenv local
rbenv global
rbenv versions

另外，你是如何启动rails控制台的？你在项目的目录中做rails console吗？

如果您启动irb然后执行require 'set'，它是否有效，或者是否会引发错误？

无法使我的rails控制台工作
