Rails无法加载这样的文件--bcrypt

Question

我的应用程序在本地加载,但任何交互都会引发错误:

Started GET "/users/sign_in" for 127.0.0.1 at 2016-11-22 15:42:14 +1100
  ActiveRecord::SchemaMigration Load (1.0ms)  SELECT "schema_migrations".* FROM

Processing by Users::SessionsController#new as HTML

Completed 500 Internal Server Error in 4ms (ActiveRecord: 0.0ms)


LoadError (cannot load such file -- bcrypt):

app/controllers/users/sessions_controller.rb:6:in `new'
  Rendering C:/Ruby23-x64/lib/ruby/gems/2.3.0/gems/actionpack-5.0.0.1/lib/action

我正在运行Windows7 64位,Ruby23-x64,Rails 5.0.0.1,我安装的唯一bcrypt gem是:bcrypt-3.1.11.

我在这里尝试了解决方案:无法加载这样的文件 - 1.9/bcrypt_ext(LoadError)但bcrypt-ruby不再存在于更新版本的ruby.

编辑:如果我运行gem install bcrypt,我会得到一个额外的bcrypt gem:C:\ Ruby23-x64\lib\ruby​​\gems\2.3.0\gems.我现在有2个bcrypts:

• C:\ Ruby23-64\LIB \红宝石\宝石\ 2.3.0 \宝石\ bcrypt-3.1.11
• C:\ Ruby23-64\LIB \红宝石\宝石\ 2.3.0 \宝石\ bcrypt-3.1.11-64-的mingw32

我要保留哪一个,以及在Gemfile中需要更改哪些内容？

我错过了什么？

Answer 1

你把它gem 'bcrypt'放进你的Gemfile.

如果你把它跑了bundle install,restart你rails server呢？

如果您仍然遇到此问题,可以执行以下操作:

• 首先卸载bcrypt并bcrypt-ruby运行以下两个命令:

  gem uninstall bcrypt 和 gem uninstall bcrypt-ruby

• 再次安装 gem install bcrypt --platform=ruby

• 在你的Gemfile写作gem 'bcrypt-ruby', '3.1.5', :require => 'bcrypt'

• 然后运行bundle install和restart你的rail server
