Ruby on Rails软件包安装不工作

所以我目前正在使用Michael Hartl教程学习Ruby on Rails（目前确实是noob--对编程来说真的很新颖）。我试图编辑我正在制作的“hello_app”中的gemfiles - 正如迈克尔告诉我这样做的，但是当我返回终端运行捆绑安装时 - 我得到以下内容而不是安装：Ruby on Rails软件包安装不工作

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 
> gem 'sqlite3' , 1.3.12 
# # Call 'byebug' anywhere in the code to stop execution and get a debugger console 
# -------------------------------------------

有人能让我知道发生了什么吗？我该如何解决它？下面是我在我的Atom文本编辑器：

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 

# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'

# gem 'bcrypt', '~> 3.1.7' 

# Use Capistrano for deployment 
# gem 'capistrano-rails', group: :development 

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]

非常感谢您的经历this.Please做解释什么操作系统回事，所以我学习以及纠正错误。显然你可以告诉我这个游戏真的很新，但是很想学习！

请注意，谢谢！

试试这一个，定义宝石定义没有给你'Gemfile'版本'宝石“sqlite3''。或给予版本试试这个'宝石“的sqlite3”，“1.3.12'' –

有两个错别字/在group :development, :test错误，从您的Gemfile：

你缺少你sqlite3宝石版引号（或双引号）：
```
gem 'sqlite3' , 1.3.12 
      ^ ^
```

有一个缺失和尾随逗号, in gem 'byebug'

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
