Question

嘿，当我尝试启动rails服务器时，我收到以下错误

有什么想法吗？目前还没有可行的解决方案......

顺便说一句，我运行Windows 8 ......可能就是问题所在：D

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

我成功解决了这个问题（更新我的Gemfile）：

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

Answer 2

如果您对gem bcrypt有疑问，请按以下步骤操作：

1。更改为bundle show bcrypt + ext\mri\找到的gem目录，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，仅当您的DevKit环境设置正确（运行devkitvars.bat）时才有效。

Answer 3

我在Windows上遇到了类似的问题但是使用了Ruby 2.0和Rails 3.2.15。它现在至少需要3.1.2：

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

链接： https://github.com/rails/rails/pull/12325

Answer 4

在你的gemfile中评论“gem'bcrypt-ruby'，'〜＆gt; 3.0.0'” 这应该是工作

Answer 5

相关版本将不断变化。你可以在这里找到最新的稳定版本号：rubygems.org/gems/bcrypt-ruby

Answer 6

如果有人在Windows 64位上仍然遇到此问题（特别是使用设计），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-data gem更改为： gem 'tzinfo-data', platforms: [:mingw, :mswin, :x64_mingw]

无法加载此类文件 - 1.9 / bcrypt_ext（LoadError）
