新 rails 项目中的耙子 db:create 出错

Question

我收到以下错误：

耙子中止！
NameError：未初始化的常量 Sass::Script /home/nikhil/Nurture/careerpal-back/config/application.rb:7:in <top (required)>' /home/nikhil/Nurture/careerpal-back/Rakefile:4:in' （使用 --trace 查看运行ning 任务的完整跟踪）

Gemfile 是

source 'https://rubygems.org'

# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
gem 'rails', '4.2.5.1'
# Use sqlite3 as the database for Active Record
gem 'sqlite3'
# Use SCSS for stylesheets

# Use Uglifier as compressor for JavaScript assets

group :development, :test do

  gem 'byebug'
end

group :development do
  # Access an IRB console on exception pages or by using <%= console %> in views
  gem 'web-console', '~> 2.0'

  gem 'spring'
end

我已经通过运行ning bundle update 将所有 gem 更新到最新版本并更改了 sass-rails gem 到特定版本。还是不行运行

Gemfile.lock 有这些行

sass (3.4.21)
sass-rails (5.0.4)
  railties (>= 4.0.0, < 5.0)
  sass (~> 3.1)
  sprockets (>= 2.8, < 4.0)
  sprockets-rails (>= 2.0, < 4.0)
  tilt (>= 1.1, < 3)

但是运行ning bundle install 给了我这个：

Using sass 3.4.21
Using sass-rails 5.0.4

编辑：我之前用 4.2.4 创建了一个 api 只有 rails 的项目。还行运行

感谢帮助。提前致谢。

Answer 1

运行一步一步，首先：

gem install bundler

然后

bundle install

&然后

bundle exec rake db:create

为了学习bundler, Create rails project

希望能帮到你

Answer 2

我只是重新安装了 ruby+rails，一切正常。

我删除了 ~/.rbenv 文件夹和运行 sudo apt-get purge ruby

然后使用 Official Page 安装 ruby 和 rails。

重要的是，一旦我创建了一个新项目，系统就会提示我安装另一个 gem 来解决一些依赖关系 gem install rdoc-data
