包stdout: Nothing写的bundle stderr: Nothing写的

Question

因此，我最近设置了一个Azure VM，并一直试图将我们的应用程序部署到Azure。我为一堆错误而争吵，但在运行cap production deploy:check --trace之后，我真的被困在这里了

我们使用Ansible来设置服务器，而nginx在服务器上运行得很好。现在我们只是尝试将该死的东西部署到机器上，但是我们遇到了一个奇怪的问题，在这个问题上，它无法作为部署用户执行，不管原因是什么都没有写好。

任何帮助都将不胜感激。

Answer 1

根据来源，退出状态18意味着Ruby版本不匹配。通常情况下，这表明您的Gemfile中有一个Gemfile行，它需要一个与执行Bundler不同的版本(本例中为2.2.0)。

令人惊讶的是，它说什么都没有写到stdout或stderr，因为在这种情况下，邦德勒通常会打印错误。可能还有导致错误输出被抑制的另一个问题。
