无法构建 gem 本机扩展（Windows 10）来安装 mini_racer 和 libv8-node

Question

尝试使用

bundle exec jekyll serve

使用jekyll生成网站并被返回：

在本地安装的 gem 中找不到 gem 'mini_racer'。运行bundle install来安装缺少的gems。

所以我做到了

bundle install

并收到此错误：

An error occurred while installing libv8-node (18.16.0.0), and Bundler cannot
continue.

In Gemfile:
  mini_racer was resolved to 0.8.0, which depends on
    libv8-node

我也尝试过

gem install libv8

并被退回：

我也尝试过

gem update

，这表明我的gem已更新。也做了

winget install ruby-dev

，它刚刚返回：

未找到符合输入条件的包。

我也遇到了同样的问题，我老板选择的模板需要安装“mini_racer”，但我不知道如何解决。如果您知道答案，请随时通知我。谢谢。
