我已经使用 Ruby 3.0.0 从头开始​​创建了一个新的 Rails 6.1 应用程序。
我跑了 db:create并生成了一个带有一些字符串列的单个模型，后跟 rails db:migrate .
我跑了rails test但得到这个需要 rexml 错误:

我完全不确定是什么原因造成的。 Rails 是最新的。任何人都可以指出我正确的方向吗？

最佳答案

rexml gem 是自 Ruby 3.0.0 以来的捆绑 gem。
所以你必须添加 rexml至 Gemfile .
在 Ruby 2.6 和 2.7 上，rexml gem 是默认的 gem。
所以默认 rexml如果 Gemfile 使用不包括 rexml .
在这些版本的 ruby​​ 上，您必须添加 rexml至 Gemfile仅当您想使用特定的 rexml版本。

关于ruby-on-rails - Rails 6.1，Ruby 3.0.0 : tests error as they cannot load rexml，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/65479863/
