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

Question

嘿，当我尝试启动 rails 服务器时出现以下错误

有什么想法吗？目前没有可行的解决方案...

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'

Answer 2

如果您在使用 gem bcrypt 时遇到问题，请按照以下步骤操作：

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

Answer 3

我遇到了类似的问题，但在 Windows 上使用 Ruby 2.0 和 Rails 3.2.15。现在至少需要 3.1.2：

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

Answer 4

在你的 gemfile 中注释掉 "gem 'bcrypt-ruby', '~> 3.0.0'" 这应该是工作

Answer 5

相关版本会不断变化。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（尤其是在设计方面），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"

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