Rake Gems安装错误

Question

我在尝试安装gem时遇到以下错误:

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

如果任务未在输出中列出,rake -T则它未定义,您无法运行它.

Rails 3删除了这个任务,转而使用Gemfile和bundler作为官方gem安装程序,因为gems:install正常工作通常很棘手.
