Ruby on rails 如何避免bootsnap和railties导致此错误？

----更新

我已经在另一个目录中克隆了repo，并再次抛出了all进程，不过这次我注意到问题只有在使用以下命令后才会出现：

bundle install --deployment --without development test

如果我只使用

bundle安装

，我就可以

rails c

毫无问题

为什么会这样？使用这些标志是否重要？我这么做只是因为

----更新

我正试图在Ubuntu上部署ruby应用程序。我曾经通过

rails c

在错误的位置正确运行过一次相同的回购。 然后我在正确的位置（

var/www/app/code

）执行了所有相同的步骤，但当我运行

rails c

时，我遇到了以下问题：

你的错误在最后一行

bundle安装—部署—无需开发测试

command仅安装生产和通用gems。不安装开发或测试gems。Rails读取设置环境的环境变量<代码>RAILS_ENV变量，如果未设置RAILS默认接受开发。bundler尝试加载所有gems+开发组gems。但是

bundle安装--部署--没有开发测试

命令，只安装生产和通用gems。所以未安装listen gem，因为listen gem位于开发组中

RAILS\u ENV=production bin/RAILS c

命令未抛出错误，因为未尝试加载开发gems。

如果要将生产模式运行到RAILS，首先必须添加

RAILS\u ENV=production

环境变量或在命令之前。您的错误似乎与

config/environments/development.rb:51

内容有关？

config.file\u watcher=ActiveSupport:：EventFileUpdateChecker

抱歉，我最近看到了错误。。。
