【问题描述】：

构建一个 rails 应用程序，过去几周一切正常，在 react 应用程序上使用 ruby​​ on rails 也是如此。

我用 \ 示例 bundle exec rails s\ 输入错误 bundle exec rails s 并且终端将其识别为新行，我只是控制 c 出来，在推送到 git 后，我​​使用上面的命令再次在本地运行程序我返回以下错误。

我尝试了rails s 和bundle exec rails c 的相同错误我尝试使用--force 和npm 包重新安装ruby gem。

我什至不知道从哪里开始出现这个错误。

我对 ruby​​ 和 rails 还很陌生。我不明白这个错误是如何或从哪里开始的，之前一切都很好。

【问题讨论】：

快速浏览一下 webpacker 代码，看起来您的 manifest.json 已损坏。尝试运行 rails webpacker:clobber 来清除现有的编译输出，然后再试一次。

【参考方案1】：

有没有可能是 bootsnap 缓存损坏？ 尝试在您的项目文件夹中删除tmp/cache（或您可以在config/boot.rb 中配置的任何其他路径以用于引导快照），也可以尝试使用spring stop，以防它在您的项目中运行。
