ruby-on-rails - Ubuntu，Ruby，Ruby on Rails安装问题（访问localhost：3000）

这是我第一次学习编码，第一次使用Linux，第一次使用stackeroverflow，所以我不知道它出错的地方是不是很明显。

我已遵循本指南https://gorails.com/setup/ubuntu/16.04，所有内容都按照指南的说法运行，直到我进入此部分：

运行bundle install --local /usr/lib/ruby/2.3.0/rubygems/core_ext/kernel_require.rb:55:in require': cannot load such file -- bundler (LoadError) from /usr/lib/ruby/2.3.0/rubygems/core_ext/kernel_require.rb:55:in要求＆＃39; 来自/usr/lib/ruby/vendor_ruby/rails/generators/app_base.rb:328:in bundle_command' from /usr/lib/ruby/vendor_ruby/rails/generators/app_base.rb:344:in run_bundle＆＃39; 来自（eval）：1：run_bundle' from /usr/lib/ruby/vendor_ruby/thor/command.rb:27:in运行＆＃39; 来自/usr/lib/ruby/vendor_ruby/thor/invocation.rb:126:in invoke_command' from /usr/lib/ruby/vendor_ruby/thor/invocation.rb:133:in阻止invoke_all＆＃39; 来自/usr/lib/ruby/vendor_ruby/thor/invocation.rb:133:in each' from /usr/lib/ruby/vendor_ruby/thor/invocation.rb:133:in map＆＃39; 来自/usr/lib/ruby/vendor_ruby/thor/invocation.rb:133:in invoke_all' from /usr/lib/ruby/vendor_ruby/thor/group.rb:232:in发送＆＃39; 来自/usr/lib/ruby/vendor_ruby/thor/base.rb:440:in start' from /usr/lib/ruby/vendor_ruby/rails/commands/application.rb:17:in＆＃39; 来自/usr/lib/ruby/2.3.0/rubygems/core_ext/kernel_require.rb:55:in require' from /usr/lib/ruby/2.3.0/rubygems/core_ext/kernel_require.rb:55:in要求＆＃39; 来自/usr/lib/ruby/vendor_ruby/rails/cli.rb:14:in <top (required)>' from /usr/lib/ruby/2.3.0/rubygems/core_ext/kernel_require.rb:55:in要求＆＃39; 来自/usr/lib/ruby/2.3.0/rubygems/core_ext/kernel_require.rb:55:in require' from /usr/bin/rails:9:in＆＃39; tom @ Laptop：〜$ cd myapp tom @ Laptop：〜/ myapp $ rake db：create 耙子流产了！ LoadError：无法加载此类文件 - bundler / setup /home/tom/myapp/config/boot.rb:3:in <top (required)>' /home/tom/myapp/config/application.rb:1:in＆＃39; / home / tom / myapp / Rakefile：4：在<top (required)>' (See full trace by running task with --trace) tom@Laptop:~/myapp$ rails server /usr/lib/ruby/2.3.0/rubygems/core_ext/kernel_require.rb:55:in中要求＆＃39;：无法加载此类文件 - bundler / setup（LoadError）来自/usr/lib/ruby/2.3.0/rubygems/core_ext/kernel_require.rb:55:in require' from /home/tom/myapp/config/boot.rb:3:in＆＃39; 来自bin / rails：3：require_relative' from bin/rails:3:in＆＃39;

抱歉，我不知道如何正确格式化。当我访问localhost：3000时，我发现网络错误。

有谁知道如何解决这个问题？谢谢你的时间。
