运行捆绑安装时导致未定义方法`dir_mode ='的原因

Question

我重温了一个 2 个月没有动过的 Rails 4.2.11.1 应用程序。该应用程序使用 CircleCI 进行部署。之前，当触发构建时，没有任何问题。在这两个月里，代码没有发生任何变化。触发构建并运行bundle install --deployment --path vendor/bundle时，返回以下错误：

#!/bin/bash -eo pipefail
bundle install --deployment --path vendor/bundle
Don't run Bundler as root. Bundler can ask for sudo if it is needed, and
installing your bundle as root will break this application for all non-root
users on this machine.

Make sure that `gem install rake -v '12.3.3'` succeeds before bundling.

我不知道是什么导致了NoMethodError 的问题。 Trieg 搜索 dir_mode= 方法但无济于事。我真的很感激任何关于如何摆脱这个问题的提示。提前致谢！

我之前也遇到过同样的问题。 bundle update --bundler 似乎是为我解决了这个问题。
