捆绑执行padrino启动的问题

Question

我在执行一项任务时遇到了困难，到目前为止，这一任务在过去一年中一直没有问题。在我的机器上开发我的Ruby Padrino应用程序。我会用流浪汉。一旦流浪者启动，我将在putty中加载设置并执行"bundle exec -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，我现在收到以下错误：

RuntimeError: Rack config file `0.0.0.0` must have `.ru` extension

在此之前，我还必须运行bundle安装，所以我想知道它是一个更新的创业板文件，导致了这个问题还是其他原因。如有任何资料，将不胜感激。

Answer 1

如果在引号中包含该命令，则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，并且在问题https://github.com/bundler/bundler/issues/4480中有报道。

Answer 2

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，但如果有人能给我一些启示，我会很感激的。
