2 个解决方案

#1

It seems you need to

看来你需要这么做

require 'byebug'

需要“byebug”

I was in the same situation and require failed with 'cannot load such file' error but adding to the Gemfile worked.

我也遇到了同样的情况，并要求失败，因为“无法加载此类文件”错误，但是向Gemfile中添加的操作是有效的。

#2

Make sure you haven't installed the gems with bundle install --without development option.

确保您没有安装附带bundle install的gems——没有开发选项。

If that is the case just run bundle install --with development

如果是这样，那就运行bundle install——并进行开发
