如何从来源https://github.com/cmedley/terraforming来构建和安装这个gem包？

Question

我想构建并使用这个github项目https://github.com/cmedley/terraforming

我正在尝试按照此处https://github.com/cmedley/terraforming#development的说明来构建和运行程序包。

但是，当我运行./script/setup时，我得到了

Traceback (most recent call last):
    2: from /usr/local/bin/bundle:23:in `<main>'
    1: from /usr/local/Cellar/ruby/2.6.3/lib/ruby/2.6.0/rubygems.rb:302:in `activate_bin_path'
/usr/local/Cellar/ruby/2.6.3/lib/ruby/2.6.0/rubygems.rb:283:in `find_spec_for_exe': can't find gem bundler (>= 0.a) with executable bundle (Gem::GemNotFoundException)

我想念任何明显的东西吗？我没有很多红宝石经验，并且我完全不了解Ruby生态系统。

问题中显示的错误已由Max Pleaner的建议解决。

 gem install bundler

但是很快就遇到了第二个问题：

Gem :: Ext :: BuildError：错误：无法构建gem本机扩展。

当前目录：/Users/antkong/Documents/Personal/wd/terraforming-assume-role/bin/ruby/2.3.0/gems/json-2.2.0/ext/json/ext/generator/System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/bin/ruby -r./siteconf20191105-34055-mnnpg3.rb extconf.rb mkmf.rb找不到红宝石的头文件位于/System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/lib/ruby/include/ruby.h

extconf失败，退出代码1

Gem files will remain installed in /Users/antkong/Documents/Personal/wd/terraforming-assume-role/bin/ruby/2.3.0/gems/json-2.2.0

An error occurred while installing json (2.2.0), and Bundler cannot continue.
Make sure that `gem install json -v '2.2.0' --source 'https://rubygems.org/'` succeeds before bundling.

In Gemfile:
  coveralls was resolved to 0.8.21, which depends on
    simplecov was resolved to 0.14.1, which depends on
      json

xcode-select --install
sudo xcodebuild -license accept
