无法激活 bcrypt-ruby (~> 3.0.0)，已经激活 bcrypt-ruby-3.1.2? [英] Unable to activate bcrypt-ruby (~> 3.0.0), already activated bcrypt-ruby-3.1.2?

问题描述

我正在尝试安装 bcrypt 来处理密码.

I'm trying to install bcrypt to handle passwords.

我运行 gem install bcrypt-ruby 并得到:

....Successfully installed bcrypt-ruby-3.1.2

我添加了 gem "bcrypt-ruby", "~> 3.1.2" 并运行 bundle install，然后重新启动了运行程序的服务器，但我得到了错误:

I added gem "bcrypt-ruby", "~> 3.1.2" and ran bundle install, and restarted the server which ran the program but I got the error:

get Gem::LoadError in UsersController#new 
can't activate bcrypt-ruby (~> 3.0.0), already activated bcrypt-ruby-3.1.2. Make sure all dependencies are added to Gemfile.


format: { with: VALID_EMAIL_REGEX },
uniqueness: { case_sensitive: false }
**has_secure_password** <---Error
validates :password, length: { minimum: 6 }
end

推荐答案

~>3.0.0 版本与 ~> 冲突3.1.2 一，因为比较发生在3.0.~ 和3.1.~，并且失败.你刮胡子改~>3.0.0 到 ~>3.0，为了比较3.~和3.1.

The ~> 3.0.0 version conflicts with ~> 3.1.2 one, because comparison takes place 3.0.~ to 3.1.~, and failed. You shave to change ~> 3.0.0 to ~> 3.0, in order to compare 3.~ to 3.1.

如果你做不到，你必须查看Gemfile.lock，哪个gem需要3.1.2版本的bcrypt-ruby，并尝试将其降级.

If you are unable to do it, you have to see into Gemfile.lock, which gem require 3.1.2 version of bcrypt-ruby in, and try to downdrade it.
