嘿，当我尝试启动 rails 服务器时出现以下错误

有任何想法吗？目前没有任何可能的解决方案有效......

顺便说一句，我运行 Windows 8 ......可能根本就是问题所在：D

今天早上，我也面临同样的问题（Windows 7）。让我推荐看看这里 https://github.com/codahale/bcrypt-ruby/issues/72

我成功地解决了这样的问题（更新我的 Gemfile）： 

gem 'bcrypt-ruby', '3.1.1.rc1', :require => 'bcrypt'

如果您对 gem 有问题bcrypt，请按照以下步骤操作：

1.切换到bundle show bcrypt+找到的 gem 目录ext\mri\，例如：c:\RailsInstaller\Ruby2.2.3\lib\ruby\gems\2.2.0\gems\bcrypt-3.1.10-x86-mingw32\ext\mri

2.运行ruby extconf.rb

3.运行make

4. make install

请注意，这仅在您的DevKit环境设置正确（运行devkitvars.bat）时才有效。

I encountered a similar issue but with Ruby 2.0 and Rails 3.2.15 on Windows. It now requires at least 3.1.2:

gem 'bcrypt-ruby', '~> 3.1.2'

相关版本会不断变化。您可以在此处找到最新的稳定版本号：rubygems.org/gems/bcrypt-ruby

在你的 gemfile 中注释掉 "gem 'bcrypt-ruby', '~> 3.0.0'" 这应该是可行的

如果有人在 Windows 64 位上仍然遇到此问题（尤其是设计），请尝试安装 Ruby 64 位，然后将 rails 作为 gem（而不是使用 rails 安装程序），然后添加： gem 'bcrypt-ruby', '~> 3.0.0', :require => "bcrypt"

您可能需要将tzinfo-datagem 更改为： gem 'tzinfo-data', platforms: [:mingw, :mswin, :x64_mingw]
