设计中的 LoadError::RegistrationsController#create

Question

我正在使用 devise 的 gem，但在 Devise::RegistrationsController#create 中出现错误 LoadError 无法加载此类文件 -- bcrypt_ext .. 我尝试对此问题进行一些研究，并尝试按照给出的说明进行操作(https://stackoverflow.com/questions/35422463/loaderror-in-deviseregistrationscontrollercreate-cannot-load-such-file-bc)

但还是有这个问题。有什么建议吗？

注意：我使用的指南是 video guide，我在 Windows 7 上使用 ruby​​ on rails

Answer 1

我也遇到了同样的错误，我的问题已经解决了，请尝试solution 3

问题是编译的 windows gem。最好删掉，只包含纯ruby版本。

解决方案一：

您可以将 bcrypt_ext.so 从 \lib\2.1 复制到 \lib 与 bcrypt.rb 相同的文件夹

解决方案二：

您可以使用 gem install bcrypt --platform=ruby，即使我无法从始终使用编译版本的 rails 中选择它

解决方案三：

git 克隆https://github.com/codahale/bcrypt-ruby.git

cd bcrypt-ruby

gem 构建 bcrypt.gemspec

gem 安装 gem 编译器

gem 编译 bcrypt-3.1.10.gem

gem install bcrypt-3.1.10-x64-mingw32.gem --local

Answer 2

请做一件事，它会解决你的问题

删除版本，然后把它写在你的 Gemfile 中

gem 'bcrypt-ruby'
