Question

所以我目前正在使用Michael Hartl教程学习Ruby on Rails（目前真的是noob - 对于编程来说真的很新）。我试图在＆＃34; hello_app＆＃34;中编辑gemfiles。我正在制作 - 正如迈克尔所说，但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
 >    gem 'sqlite3' , 1.3.12
#    # Call 'byebug' anywhere in the code to stop execution and get a debugger console

有人可以让我知道发生了什么事吗？我该如何解决？这是我在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

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

# Use Redis adapter to run Action Cable in production

# Use Capistrano for deployment

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]

非常感谢你仔细阅读。请解释一下os的内容，以便我学习并纠正错误。显然你可以告诉我这个游戏真的很新，但我很想学！

请指教，谢谢！

Answer 1

group :development, :test的{{1}}中有两个拼写错误/错误：

Gemfile宝石版中缺少引号（或双引号）：
```
sqlite3
```
gem 'sqlite3' , 1.3.12 ^ ^
中有一个缺失和尾随的逗号,
```
gem 'byebug'
```

所以gem 'byebug', '9.0.0' platform: :mri, ^ ^应如下所示：

group :development, :test

Ruby on Rails捆绑安装不起作用
