bundle exec jekyll serve: 无法加载此类文件

Question

我正在尝试为 Github Page/Jekyll 网站做贡献，并希望能够在本地可视化更改，但是当我运行 bundle exec jekyll serve 但我得到了这个输出:

Bundle updated!

此外，这就是 gemfile 的样子：

source "https://rubygems.org"
gem 'jekyll-scholar', group: :jekyll_plugins

# If you want to use GitHub Pages, remove the "gem "jekyll"" above and
# uncomment the line below. To upgrade, run `bundle update github-pages`.
gem "github-pages", "~> 204", group: :jekyll_plugins

# If you have any plugins, put them here!
group :jekyll_plugins do
  gem "jekyll-feed", "~> 0.6"
end

# Windows does not include zoneinfo files, so bundle the tzinfo-data gem
gem "tzinfo-data", platforms: [:mingw, :mswin, :x64_mingw, :jruby]

# Performance-booster for watching directories on Windows
gem "wdm", "~> 0.1.0" if Gem.win_platform?

为什么不起作用？我是 ruby 和 jekyll/github 页面的新手，但我创建了另一个 Github 页面的网站并且这个命令没有问题...

Answer 1

我遇到了同样的问题，我在 https://github.com/jekyll/jekyll/issues/8523

找到了解决方法

将 gem "webrick" 添加到您网站的 Gemfile 中。比运行bundle install

此时你可以运行bundle exec jekyll serve

对我来说很管用！

Answer 2

我看到您正在使用 github-pages:204 和 jekyll:3.8.5。

我使我的项目具有相同的依赖关系：

bundle update github-pages
bundle add webrick

Answer 3

感谢@choas 的评论，这是我解决问题的方法：

更新了 github 页、jekyll 和 jekyll-feed gem，作者是运行ning gem install github-pages、gem install jekyll 和 gem install jekyll-feed。我必须执行此步骤，因为简单 bundle update 没有安装最新版本。
将Gemfile中的那些gems修改为最新版本。
运行 bundle update
终于运行bundle exec jekyll serve

我不确定所有这些步骤是否都是多余的，因为我对 Ruby/Github Pages/Jekyll 不是很熟悉，但它确实有效。

Answer 4

安装 webrick 和 jekyll-mentions：打开终端并输入 gem install webrick 然后 gem install jekyll-mentions.
打开你的gem文件并在插件中添加gem“jekyll-mentions”和gem“webrick”：

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

导航回终端，然后执行bundle install。

我想你可以走了。这个过程对我有用！

Answer 5

我也遇到这个错误。解决方案在 documentation itself.

If you are using Ruby version 3.0.0 or higher, step 5 may fail(bundle exec jekyll serve). You may fix it by adding webrick to your dependencies: bundle add webrick

或在Gemfile中添加gem "webrick"，然后bundle install。
