Rake Gems安装错误

Question

尝试安装gem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)

Answer 1

如果任务未在rake -T的输出中列出，则表明它未定义，您无法运行它。

Rails 3删除了此任务，转而使用Gemfile和bundler作为官方gem安装程序，因为gems:install通常很难正常工作。
