The dependency tzinfo-data (>= 0) will be unused by any of the platforms Bundler is installing for. Bundler is installing for ruby but the dependency is only for x86-mingw32, x86-mswin32, x64-mingw32, java. To add those platforms to the bundle, run `bundle lock --add-platform x86-mingw32 x86-mswin32 x64-mingw32 java`.

安装 Rails
在终端中执行以下命令:
sudo gem install rails
可能会遇到以下问题:
ERROR: Error installing rails:
activesupport requires Ruby version >= 2.2.2.
使用:
ruby -v
查看当前版本
ruby 2.0.0p648 (2015-12-16 revision 53162) [universal.x86_64-darwin16]
升级 ruby
这一过程请参考:macOS Ruby版本需要升级到2.2.2以上
升级完成后再执行上面的安装步骤。
创建 Rails 项目
1、查看 Rails 帮助,执行
rails
不需要带任何参数,输出的最后会给出创建项目的命令。
2、创建一个新项目
rails new ~/Code/Ruby/weblog
创建项目执行到
run bundle install
时可能会出现提示:
�大概的意思是需要处理依赖关系。
3、处理依赖关系
切换到新建的项目目录:
cd ~/Code/Ruby/weblog
根据提示执行:
bundle lock --add-platform x86-mingw32 x86-mswin32 x64-mingw32 java
由于刚刚的
bundle install
没有执行完成,我们再执行
bundle install
4、启动服务器
rails server
5、打开浏览器,访问: http://localhost:3000/
Yay! You’re on Rails!
看到类似文章顶部图片的页面了吧,恭喜你,搭建成功了。
