我尝试重新安装/重新安装并清理每个版本的 ruby，但均未成功。我使用 Ruby 2.3.3 和 rails 5.1.4。谢谢

【问题讨论】：

运行命令bundle update 并再次检查。
@Salil 感谢您的回答，但仍然抛出相同的错误。
确保您没有将非 UTF-8 字符粘贴到控制台中。只需输入rails c 7 检查。也参考：-github.com/ConnorAtherton/rb-readline/issues/139

【解决方案1】：

因为你在 Windows 上（我假设你有 D:/）：

尝试在您的development 组中安装rb-readline gem。这是解决 readline 问题的最简单方法。

还有其他solutions，如果这不起作用。
