这是rails s的错误代码

我不知道它来自哪里

如果您想查看任何页面，请告诉我，我会上传它

标签： ruby-on-rails ruby ruby-on-rails-4

【解决方案1】：

首先注释掉# gem bcrypt, '3.1.11'并运行bundle install。然后用gem uninstall bcrypt卸载gem。然后重新安装gem install bcrypt --platform=ruby。重要的部分，取消注释gem 'bcrypt', '~> 3.1.11', platforms: [:ruby, :x64_mingw, :mingw]然后捆绑安装。那就是它。注意最后的mingw部分。这应该是关键。

但是没有 gem 'bcrypt' 我能保护密码吗？
停止。您不删除宝石，请仔细阅读答案。您卸载 bcrypt 并为您的 win 平台正确安装。
很好，我的服务器现在启动了，但是 rails 测试告诉我其他事情。
C:\Sites\sample_app>rails 测试迁移正在等待。要解决此问题，请运行：bin/rails db:migrate RAILS_ENV=test'
为测试环境运行迁移 bin/rails db:migrate RAILS_ENV=test'

【解决方案2】：

a) gem 卸载 bcrypt-ruby

b) 在您的 gemfile 中，添加

gem 'bcrypt', git: 'https://github.com/codahale/bcrypt-ruby.git', :require => 'bcrypt'

c) 捆绑安装

这适用于 Windows

祝你好运
