我该如何继续？

最佳答案

我有同样的问题。我所做的就是在做；

gem install --version '0.2.7' mysql2

然后在 Rails 的 GemFile 上。应该看起来像这样。

gem 'mysql2', '0.2.7'

然后再试一次。希望对您有所帮助。

  10. ruby - 使用 ruby​​ 将 HTML 转换为纯文本并维护结构/格式 - 2

    我想将html转换为纯文本。不过，我不想只删除标签，我想智能地保留尽可能多的格式。为插入换行符标签，检测段落并格式化它们等。输入非常简单，通常是格式良好的html(不是整个文档，只是一堆内容，通常没有anchor或图像)。我可以将几个正则表达式放在一起，让我达到80%，但我认为可能有一些现有的解决方案更智能。 最佳答案 首先，不要尝试为此使用正则表达式。很有可能你会想出一个脆弱/脆弱的解决方案，它会随着HTML的变化而崩溃，或者很难管理和维护。您可以使用Nokogiri快速解析HTML并提取文本:require'nokogiri'h
