我在我的應用程序文件夾中,但命令rails s
不起作用。我閱讀了Stack Overflow上的很多帖子,其中大部分似乎來自不在其應用目錄中的用戶。爲什麼「rails s」不能從app目錄中運行?
此外,我建了一些其他的應用程序。我檢查了這些,Rails服務器適用於所有這些應用程序。這是我無法啓動的唯一一個。
的which rails
輸出:
/Users/jmcrist/.rvm/gems/ruby-2.0.0-p247/bin/rails
的rails s
輸出:
MacBook-Pro:first_app jmcrist$ rails s

Description:
The 'rails new' command creates a new Rails application with a default
directory structure and configuration at the path you specify.
You can specify extra command-line arguments to be used every time
'rails new' runs in the .railsrc configuration file in your home directory.
Note that the arguments specified in the .railsrc file don't affect the
defaults values shown above in this help message.
Example:
rails new ~/Code/Ruby/weblog
This generates a skeletal Rails installation in ~/Code/Ruby/weblog.
See the README in the newly created application to get going.
我通過哈特爾的Rails的教程工作,他做了不少修改的Gemfile中。我想知道這是否是原因?
source 'https://rubygems.org'
gem 'rails', '3.2.13'
group :development do
gem 'sqlite3', '1.3.5'
end
# Gems used only for assets and not required
# in production environments by default.
group :assets do
gem 'sass-rails', '3.2.5'
gem 'coffee-rails', '3.2.2'
gem 'uglifier', '1.2.3'
end
gem 'jquery-rails', '2.0.2'
group :production do
gem 'pg', '0.12.2'
end
