Question

我已经用rbenv将ruby重新安装到版本2.4.2，安装后我想运行rails控制台，但是我执行的任何使用我代码中定义的模块的操作都会导致此错误：

(pry) output error: #<LoadError: cannot load such file -- enc/trans/single_byte>

还有一段很长的轨迹，像这样：

我已经找到了答案https://stackoverflow.com/a/13400402/3663124，是的，我有yml文件带有非ASCII字符，但是以前从来都不是问题。

这是rbenv安装日志：

使用rbenv到版本2.5.1的ruby我也遇到了同样的问题。用rbenv重新安装ruby以使readline使用libreadline之后。

(pry) output error: #<LoadError: cannot load such file -- enc/trans/single_byte>

它是堆栈跟踪

就我而言，重新启动pc是解决方案。通常，重新启动Shell是反映更改的方法，但是那时候我需要重新启动pc。

输出错误：＃<LoadError：无法加载此类文件-enc / trans / single_byte>
