Ruby on Rails 捆绑安装不起作用

Question

所以我目前正在使用 Michael Hartl 教程学习 Ruby on Rails（目前真的很菜鸟 - 对编程真的很陌生）。我试图编辑我正在制作的“hello_app”中的 gemfiles - 正如迈克尔所说的那样，但是当我回到终端运行捆绑安装时 - 我得到以下内容而不是安装：

Abduls-MacBook-Pro:hello_app Monahim$ bundle install

[!] There was an error parsing `Gemfile`: unexpected fraction part after numeric literal -   gem 'sqlite3' , 1.3.12
                 ^
/Users/Monahim/railsmhartl/hello_app/Gemfile:40: syntax error, unexpected tIDENTIFIER, expecting keyword_end
gem 'byebug', '9.0.0' platform: :mri, end
                            ^
/Users/Monahim/railsmhartl/hello_app/Gemfile:55: syntax error, unexpected end-of-input, expecting keyword_end. Bundler cannot continue.

 #  from /Users/Monahim/railsmhartl/hello_app/Gemfile:38
 #  -------------------------------------------
 #  group :development, :test do

#    # Call 'byebug' anywhere in the code to stop execution and get a debugger console

有人可以告诉我发生了什么吗？我该如何解决？这是我的 Atom 文本编辑器中的内容：

source 'http://rubygems.org'

git_source(:github) do |repo_name|
  repo_name = "#{repo_name}/#{repo_name}" unless repo_name.include?("/")
  "ht//githublinkhere /#{repo_name}.git"
end

group :development, :test do
  gem 'sqlite3' , 1.3.12
  # Call 'byebug' anywhere in the code to stop execution and get a debugger console
  gem 'byebug', '9.0.0' platform: :mri, 
end
# Adds support for Capybara system testing and selenium driver

group :development do
  # Access an IRB console on exception pages or by using <%= console %>   anywhere in the code.
  gem 'web-console', '>= 3.1.1'
  gem 'listen', '>= 3.0.5', '< 3.0.8'
  # Spring speeds up development by keeping your application running in the background. Read more: /github.com/railsspringlinkhere
  gem 'spring' , '1.7.2.'
  gem 'spring-watcher-listen', '~> 2.0.0'
end

# Windows does not include zoneinfo files, so bundle the tzinfo-data gem
gem 'tzinfo-data', platforms: [:mingw, :mswin, :x64_mingw, :jruby]

非常感谢您完成此操作。请解释一下操作系统发生了什么，以便我学习并纠正错误。显然，您可以看出我对这款游戏非常非常陌生，但我渴望学习！

请指教， 谢谢！

Answer 1

您的Gemfile 中的group :development, :test 中有两个错别字/错误：

1. 您的sqlite3 gem 版本中缺少引号（或双引号）：

   gem 'sqlite3' , 1.3.12
                  ^      ^ 
   

2. gem 'byebug' 中缺少逗号 ,

   gem 'byebug', '9.0.0' platform: :mri,
                        ^              ^
   

所以group :development, :test 应该是这样的：

group :development, :test do
  gem 'sqlite3', '1.3.12'
  # Call 'byebug' anywhere in the code to stop execution and get a debugger console
  gem 'byebug', '9.0.0', platform: :mri 
end
