在 Ubuntu 20.04 上安装 Jekyll 时出错（无法构建 gem 本机扩展）

Question

问题

我目前无法在运行 Ubuntu 20.04.4 的 DigitalOcean Dokku Droplet 上成功安装 Jekyll。

尝试安装 Jekyll 后，我得到以下输出：

root@dokku:~# gem install jekyll bundler
Building native extensions. This could take a while...
ERROR:  Error installing jekyll:
    ERROR: Failed to build gem native extension.

    current directory: /root/gems/gems/sassc-2.4.0/ext

故障排除

在 Droplet 上安装 Jekyll 之前，我运行了以下命令：

1. 已安装 Ruby，按照官方 Jekyll 文档：

   sudo apt-get install ruby​​-full build-essential zlib1g-dev
   

2. 已安装 ruby-dev，如此 GitHub问题上的建议线程与我有类似的问题：

   sudo apt-get install ruby​​-dev
   

3. Installed Jekyll

   gem 安装 jekyll 捆绑程序
   

下面是 Jekyll 要求页面中列出的依赖项的版本

问题

为什么我可以Jekyll 没有成功安装？

似乎大多数人的问题在于在 Ubuntu 上安装 Jekyll 时没有 ruby​​-dev。但是，我在安装 ruby​​-dev 后安装 Jekyll 仍然失败。
