我该如何解决这个问题？
答案 0 :(得分：44)
在你的gemfile中，你没有指定版本，所以你要安装最新版本的bcrypt-ruby 3.1.1，但你需要的是从3.0.0到3.0的任何版本0.9。您可以通过添加如下版本约束来实现此目的：
gem 'bcrypt-ruby', '~> 3.0.0'
版本要求来自ActiveModel的SecurePassword，它目前明确依赖于bcrypt-ruby（〜＆gt; 3.0.0）。您可以看到github的依赖关系。执行此代码时，它会查找未安装的3.0.0到3.0.9版本，因此会抛出错误。
此依赖关系刚刚更新为＆＃39;〜＆gt; 3.1.0＆＃39;几天前，但还没有进入rails activemodel gem。如果是这样，您必须相应地更新您的版本。如果您有点好奇，请commit。
答案 1 :(得分：3)
答案 2 :(得分：1)
我遇到了同样的问题。添加
gem 'bcrypt-ruby', '~> 3.0.0'
bundle install并重启服务器。为我工作
答案 3 :(得分：0)
删除Gemfile.lock并指定gem'bcrypt-ruby'，'3.0.0'。运行bundle install。实际上，在本地gem文件中应该卸载bcrypt-ruby。
答案 4 :(得分：0)
我遇到了同样的问题，但目前提供的gem 'bcrypt-ruby', '~> 3.0.0'方法不起作用，所以我实际安装了3.0.0版本
将行gem 'bcrypt-ruby', '3.0.0'添加到Gemfile并安装特定版本3.0.0（尽管它应该可以使用3.0.9版）
gem install --version='3.0.0' bcrypt-ruby
在此之后，只需验证您的捆绑安装，您可以运行bundle show bcrypt-ruby，然后您应该拥有安装此gem的路径，例如左< br /> ％RUBY_PATH％/ lib / ruby / gems / 2.0.0 / gems / bcrypt-ruby-3.0.0
在这些步骤之后，我能够毫无问题地使用bcrypt ...只是在有人仍遇到此问题的情况下发布此内容。
答案 5 :(得分：0)
使用ActiveModel has_secure_password
gem 'bcrypt-ruby', '~> 3.0.0'
有同样的问题。正如jconley所提到的，从上面的行中删除评论＃解决了我的问题。
答案 6 :(得分：0)
对我而言，只需删除/active_model/secure_password.rb中forcript版本对开发测试环境的依赖关系。
我始终确保将其添加到生产中，只是为了100％安全
答案 7 :(得分：0)
在控制台中：
$ gem install bundler
$ gem install bcrypt
$ bundle update bcrypt
答案 8 :(得分：-1)
添加; gem'bcrypt-ruby'，'〜＆gt; 3.1.1'到你的gemfile
或者，如果您特别想要3.0.0，请按照Maximus的建议添加：gem'bcrypt-ruby'，'3.0.0'
然后捆绑更新bcrypt-ruby。
您可能还想尝试删除gemfile.lock并重新运行bundle install。
