“bundle-exec-jekyll-serve”导致 LoadError

Question

我是一名新手程序员，尝试在我的 Github 博客中使用 Jekyll 主题。这是我第一次使用它......并且我在bundle exec jekyll serve命令方面遇到了问题。（仅供参考，我使用的是 Windows 操作系统。）

这是输出：

C:/Ruby30-x64/lib/ruby/gems/3.0.0/gems/kramdown-1.17.0/lib/kramdown/parser/html.rb:10:in `require': cannot load such file -- rexml/parsers/baseparser (LoadError)

    from C:/Ruby30-x64/bin/jekyll:25:in `load'
    from C:/Ruby30-x64/bin/jekyll:25:in `<main>'

我尝试了这 4 种不同的解决方案：

1.

bundle add webrick

但有同样的错误

2. （引用bundle exec jekyllserve:cannot load such file）

gem install jekyll github-pages
gem install jekyll
gem install jekyll-feed
bundle update

但有同样的错误

3.

gem install webrick
gem install jekyll -mentions

然后添加

group :jekyll_plugins do
  gem "jekyll-mentions", "1.6.0"
  gem "webrick"
end

到我的 gemfile，然后

bundle install

但有同样的错误

4. （参考https://github.com/jekyll/jekyll/issues/8523）

bundle add sdbm
bundle add webrick
bundle add net-telnet
bundle add xmlrpc

但有同样的错误。

我有什么办法可以解决这种情况吗？

Answer 1

据我了解，Ruby 将所有 stdlib 部分移动到 gems 中，有些是“默认 gems”，例如，它们通常与 Ruby 一起安装，不需要在您的 中引用Gemfile，但有些是“捆绑 gems”，它们也已安装使用 Ruby，但需要Gemfile. 问题源于这样一个事实：随着每个 Ruby 版本的发布，一些“默认 gem”变成了“捆绑 gem”。

这样的情况webrick过去也曾发生过。

在你的情况下，你很可能需要 rexml，它刚刚成为 Ruby 3.0 中的“捆绑宝石”：https://stdgems.org/rexml/

所有这些都是关于理论的，但解决方案非常简单。你只需要做

bundle add rexml

进而bundle install。
