耙宝石安装错误

Question

尝试安装gems时出现以下错误：

Mohammad-Azams-MacBook-Pro:awesomecats azamsharp$ sudo rake gems:install
Password:
(in /Projects/awesomecats)
rake aborted!
Don't know how to build task 'gems:install'

(See full trace by running task with --trace)
Mohammad-Azams-MacBook-Pro:awesomecats azamsharp$ 

Answer 1

如果该任务未在rake -T的输出中列出，则未定义该任务，因此无法运行。

Rails 3删除了此任务，转而使用Gemfile和bundler作为gems:install的官方gem安装过程，因为gems:install经常很难正常工作。
