我有Rails 4.0.0应用程序。当我运行bundle install命令时，没有问题。这是我的GemFile。

can't activate bcrypt-ruby (~> 3.0.0), already activated bcrypt-ruby-3.1.1. Make sure all dependencies are added to Gemfile.

我该如何解决？
最佳答案
在您的gemfile中，您没有指定版本，因此要安装的最新版本的bcrypt-ruby是3.1.1，但是您需要的是3.0.0到3.0.9之间的任何版本。您可以通过添加如下版本约束来实现：
gem 'bcrypt-ruby', '~> 3.0.0'
版本要求来自ActiveModel的SecurePassword，当前它对bcrypt-ruby（〜> 3.0.0）有明确的依赖性。您可以看到对github的依赖性。执行此代码时，它将查找未安装的3.0.0至3.0.9版本，因此会引发错误。
几天前，此依赖项刚刚更新为“〜> 3.1.0”，但尚未进入rails activemodel gem。完成后，您将必须相应地更新版本。如果您好奇的话，这是commit。
关于ruby-on-rails-4 - 无法激活bcrypt-ruby(〜> 3.0.0)，已经激活了bcrypt-ruby-3.1.1。确保所有依赖项都已添加到Gemfile，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/17741040/
