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

Question

因此，我运行了 bundle gem cgscraper 来为我的项目自动构建目录。但是，当尝试在 CLI 中运行它时，我收到此错误:undefined methodprefer_gems_rb?'`。

完整输出:

有人知道这是什么吗？我在谷歌上找不到任何相关信息，也没有我可以在任何地方看到的 prefer_gems_rb 方法。这只是我尝试运行的默认 bundle gem project 输出。

我遇到了同样的问题。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。这修复了它。我希望这会有所帮助。
