【中文标题】错误：找不到要导入的文件或无法读取：引导电子邮件【英文标题】：Error: File to import not found or unreadable: bootstrap-email 【发布时间】：2021-12-08 20:32:40 【问题描述】：

在将 rails 从 5.2 升级到 6.1.0 并将 ruby 从 2.5 升级到 3.0.2 后，我遇到了这个错误。它适用于 ruby 2.7 和 rails 6.0 版本。

它在 bootstrap-email 版本 0.3.0 上运行良好，但在使用 ruby 3.0.2 升级 1.0.1 后会中断。

我也在 GitHub 上提出了同样的问题，这里是链接 https://github.com/bootstrap-email/bootstrap-email/discussions/143
