Question

我已经安装了'devise'gem。

当我试图跑

rails g devise User

我收到以下错误。

我有Rails 4.2.6，Ruby 2.3.0

这是我的宝石文件

 gem 'rails', '4.2.6'
 gem 'mysql2'
 gem 'devise'
 gem 'sass-rails', '~> 5.0'
 gem 'uglifier', '>= 1.3.0'
 gem 'coffee-rails', '~> 4.1.0'
 gem 'therubyracer', platforms: :ruby

gem 'jquery-rails'

gem 'turbolinks'
gem 'jbuilder', '~> 2.0'
gem 'sdoc', '~> 0.4.0', group: :doc

 gem 'bcrypt', '~> 3.1.7'
 gem 'unicorn'
 gem 'capistrano-rails', group: :development

group :development, :test do
      debugger console
   gem 'byebug'
end

group :development do
  gem 'web-console', '~> 2.0'
  gem 'spring'
end

无法运行'rails g activeadmin：resource User'。它会抛出同样的错误。

Answer 1

您好请更改文件/home/cbls-2/academics/assistant/config/routes.rb的权限。它将起作用。

Answer 2

在你的位置我会尝试更改chmod for file导致EACCESS错误。在您的示例中，它将是/home/cbls-2/academics/assistant/config/routes.rb

Answer 3

在项目目录中运行此命令：

sudo chmod -R 1777 /tmp
