bundle exec padrino start 出现问题

Question

我很难执行过去一年运行没有问题的任务。在我的机器上开发我的 Ruby Padrino 应用程序。我会用流浪汉。一旦 vagrant 启动，我就会在 putty 中加载设置并执行 "bundle exec padrino start -h 0.0.0.0"。这通常会导致环境加载，但是在重新启动计算机后，我现在收到此错误：

在此之前我还必须运行捆绑安装，所以我想知道它是更新的 gem 文件导致了这个问题还是其他原因。如有任何信息，我们将不胜感激。

Answer 1

为了解决这个问题，我不得不将 Bundler 的版本从 1.12.0 恢复到 1.11.2。不知道发生了什么变化，但如果有人能对此有所了解，我将不胜感激。

Answer 2

如果您将命令放在引号中，该命令将按预期执行：

bundle exec 'padrino start -h 0.0.0.0'

Bundler 中的错误是已知的，并已在问题 https://github.com/bundler/bundler/issues/4480
