ruby - 尝试运行新的 bundle gem 时出现 Bundler 错误？未定义的方法“prefer_gems_rb？”

问题描述

所以，我跑去bundle gem cgscraper为我的项目自动构建目录。但是，当尝试在 CLI 中运行它时，我收到了这个错误：undefined methodprefer_gems_rb?'`。

完整输出：

有谁知道这是什么吗？我在 Google 上找不到任何关于它的信息，而且我在任何地方都看不到 prefer_gems_rb 方法。这只是bundle gem project我尝试运行的默认输出。

解决方案

我有同样的问题。我的 ruby​​ 版本是 2.6.0。我将我的 ruby​​ 版本更新到 2.7.1 并重新安装了我所有的 gem。这解决了它。我希望这有帮助。
