Question

我正在学习Hartl Tutorial，我需要安装geb bcrypt-ruby。我把它添加到Gemfile

    gem 'rails', '4.0.0.rc2'
    gem 'bootstrap-sass', '2.3.2.0'
    gem 'sprockets', '2.11.0'
    gem 'bcrypt-ruby', '3.1.2'

一切似乎都没问题，但如果我开始运行rspec spec /那么我就会收到错误：

您的应用程序中没有安装bcrypt + ruby。请将它添加到您的Gemfile和rund bundle install中 D：/RoR/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/bundler-1.3.5/lib/bundler/rubygems_integration.rb:224：在replace_gem＆＃39;中阻止：不能激活bcrypt-ruby＆lt;〜＆gt; ~3.0.0），已经激活了bcrypt-ruby-3.1.5-x86-mingw32。确保将所有依赖项添加到Gemfile。（GEM :: LoadError）

在Gemfile锁中有行：

    bcrypt (3.1.7-x86-mingw32)
    bcrypt-ruby (3.1.5-x86-mingw32)
      bcrypt (>= 3.1.3)

我尝试删除Gemfile.lock并生成新的但没有帮助。我的ruby版本是1.9.3p429和rails 4.0.0.rc2。我的操作系统是64位Win7

热烈欢迎任何好的建议;）

Answer 1

对于此错误，我发现从/lib/active_model/secure_password.rb删除版本的依赖项就可以了。

请确保在转移到制作时将其重新添加，以便以后不会出现其他错误

Answer 2

我通过编辑

中的gem版本来修复此错误

/lib/active_model/secure_password.rb

gem＆＃39; bcrypt-ruby＆＃39;，＆＃39; 3.0.1＆＃39;宝石＆＃39; bcrypt-ruby＆＃39;，＆＃39; 3.1.5＆＃39;

<强>段

begin
              gem 'bcrypt-ruby', '3.1.5'
              require 'bcrypt'
            rescue LoadError
              $stderr.puts "You don't have bcrypt-ruby installed in your application. Please add it to your Gemfile and run bundle install"
              raise
            end

Answer 3

我有同样的问题。我做了以下工作，然后再次工作

从Gemfile中删除bcrypt
运行bundle install
添加bcrypt返回
运行bundle install

“你的应用程序中没有安装bcrypt-ruby。”但在我看来，我有太多的版本;）（Hartl教程6.3）
