Question

我收到以下错误：

耙子中止了！
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

＆＃39; （通过使用--trace运行任务查看完整跟踪）

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

# Use Uglifier as compressor for JavaScript assets

end

end

我已经通过运行bundle update将所有宝石更新为最新版本，并将sass-rails gem更改为特定版本。它仍然不会运行

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 only rails项目。它没事。

帮助表示感谢。在此先感谢。

Answer 1

首先按步骤运行：

gem install bundler

然后

bundle install

＆安培;然后

bundle exec rake db:create

要了解bundler，请创建导轨project

希望能帮到你

Answer 2

我只是重新安装了ruby + rails，事情还不错。

我删除了〜/ .rbenv文件夹并运行了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，我就会被提示安装另一个gem来解决一些依赖关系gem install rdoc-data

rake db中的错误：在新的rails项目中创建
