Rails 和 capistrano 部署：捆绑标准错误：没有写

Question

我想用 capistrano3 推送一个 Rails4 应用程序。 但是当我尝试时，我得到了这些错误：

在我的 deploy.rb 中，我没有特定任务，我的 SCM 确实包含 Gemfile 和 Gemfile.lock。

有什么问题？

Answer 1

您似乎更改了 Gemfile，但没有在本地机器上运行 bundle install。 所以你的 Gemfile 和 Gemfile.lock 不同步了。

在本地机器上运行 bundle install 来更新 Gemfile.lock，然后提交并推送更改。
