杰基尔 4.0.0 |错误：未初始化常量 TZInfo::Timezone

Question

我想在实时服务器上查看网站..但我还不熟悉 jekyll

首先我尝试了bundle exec jekyll serve，这是原子终端的输出：

    PS C:\Users\user\Documents\GitHub\bioscreator-lp> bundle exec jekyll serve
    Configuration file: C:/Users/user/Documents/GitHub/bioscreator-lp/_config.yml
    Dependency Error: Yikes! It looks like you don't have tzinfo or one of its dependencies 
    installed. In order to use Jekyll as currently configured, you'll need to ins
    tall this gem. If you've run Jekyll with `bundle exec`, ensure that you have included the 
    tzinfo gem in your Gemfile as well. The full error message from Ruby is: 'can
    not load such file -- tzinfo' If you run into trouble, you can find helpful resources at 
    https://jekyllrb.com/help/!
    jekyll 4.0.0 | Error:  tzinfo
    C:/Ruby31-x64/lib/ruby/gems/3.1.0/gems/jekyll-4.0.0/lib/jekyll/external.rb:73:in `rescue 
    in block in require_with_graceful_fail': tzinfo (Jekyll::Errors::MissingDepend
    encyException)

经过一些研究后，我尝试将 gem 'tzinfo-data' 放入 gemfile 并运行 bundle install 运行bundle exec jekyll serve

还有另一个错误：

     PS C:\Users\user\Documents\GitHub\bioscreator-lp> bundle exec jekyll serve
     Configuration file: C:/Users/user/Documents/GitHub/bioscreator-lp/_config.yml
     jekyll 4.0.0 | Error:  uninitialized constant TZInfo::Timezone

    tz = TZInfo::Timezone.get(timezone)
               ^^^^^^^^^^
     C:/Ruby31-x64/lib/ruby/gems/3.1.0/gems/jekyll-4.0.0/lib/jekyll/utils/win_tz.rb:16:in 
    `calculate': uninitialized constant TZInfo::Timezone (NameError)

    tz = TZInfo::Timezone.get

我在 stackoverflow 中找到了另一个解决方案，但看起来它只适用于旧版本的 jekyll ..我的版本是 4.0.0

Answer 1

奇怪的错误。我知道我过去也遇到过类似的问题。 Jekyll 4.2.2 正在为我工​​作。我在 Windows 上，这就是我使用 WSL 设置 Jekyll 的方式。

配置

我的宝石文件（安装后包括两个不同的 tz gem）

安装还添加了具有固定最大版本的 tzinfo gem。

# Windows and JRuby does not include zoneinfo files, so bundle the tzinfo-data gem
# and associated library.
platforms :mingw, :x64_mingw, :mswin, :jruby do
  gem "tzinfo", "~> 1.2"
  gem "tzinfo-data"
end

我读到了一些关于 bundler gem 中的错误，可以通过删除平台来解决，但也许这已经解决了。这些平台根本不应该发挥作用，如果您不在 Windows 上，则可以将其省略。

红宝石版本
