"bundle-exec-jekyll-serve" 导致 LoadError

Question

我是一名新手程序员，正在尝试为我的 Github 博客使用 Jekyll 主题。这是我第一次使用它...我在使用 bundle exec jekyll serve 命令时遇到了问题。（仅供参考，我正在使用 Windows OS。）

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

但是出现同样的错误

（参考）

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

但是出现同样的错误

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

但是出现同样的错误

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

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

但是出现了同样的错误。

有什么办法可以解决这个问题吗？

Answer 1

据我了解，Ruby 将所有 stdlib 部分移动到 gems，有些是“默认 gems”，因为它们通常与 Ruby 并且在您的 Gemfile 中不需要参考，但有些是“捆绑的 gems”，它们也与 Ruby 一起安装，但需要在 Gemfile 中参考.问题源于一个事实，即每个 Ruby 版本，一些“默认 gems” 变成“捆绑 gems”。

以前webrick就发生过这种情况。

在您的情况下，您很可能需要 rexml，它刚刚成为 Ruby 3.0 中的“捆绑 gem”：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

然后是bundle install.
