search_up：Ruby 升级后出现未定义方法 \'untaint\' 错误答案

【问题标题】：search_up: undefined method 'untaint' error after Ruby upgradesearch_up：Ruby 升级后出现未定义方法 \'untaint\' 错误
【发布时间】：2022-12-30 15:08:42
【问题描述】：

业余编码器在这里。为了升级我的 Heroku 堆栈，我必须迁移到更高版本的 Ruby。我按照教程升级到 Ruby 3.2。

升级后，每当我尝试执行诸如“rails s”或“bundle update”之类的操作时，都会收到以下错误。我在网上搜索了很多但找不到任何用处。

有什么想法吗？

非常感谢任何提示

【问题讨论】：

bundle exec rails s 产生相同的输出吗？

标签： ruby-on-rails ruby rubygems bundler

【解决方案1】：

Ruby 3.2.0 删除了一些不推荐使用的方法 (taint/trust/untaint/untrust)，参考：https://bugs.ruby-lang.org/issues/16131。 Bundler 版本 1.17.3 在 shared_helpers.rb 中有该方法。尝试将捆绑器更新到 2.4.1 。
