How to build and install this gem package from source https://github.com/cmedley/terraforming?

I want to build and use this github project https://github.com/cmedley/terraforming

I am trying to follow the instruction here https://github.com/cmedley/terraforming#development to build and run the package.

However, when I run ./script/setup I got

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)

Did I miss anything obvious? I do not have much ruby experience and I am totally unfamiliar with Ruby ecosystem.

Solution

  • The error as shown in the question is solved by the suggestion from Max Pleaner.

     gem install bundler

    However it soon encountered a second problem:

    Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

    current directory: /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 can't find header files for ruby at /System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/lib/ruby/include/ruby.h

    extconf failed, exit code 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
for inspection.

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

    The solution it to follow the instruction in this answer: https://stackoverflow.com/a/58084238/58129
