ruby-on-rails - 无法加载此类文件 -- bcrypt_ext

Question

我目前在使用 Devise for Rails 5.0.1 时遇到 bcrypt 加密器的故障。我以前在使用早期的 Rails 4.2 时从未遇到过这个问题。我无法通过 Devise 注册新用户。我将发布有关我的 gemfile 和服务器日志的信息。

gem 文件.rb

gem 'bcrypt', platforms: :ruby

# Devise
gem 'devise'
gem 'devise_security_extension'

gem 'redis'
# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
gem 'rails', '~> 5.0.1'

Answer 1

我今天在使用 ruby​​ 2.3.3 和 rails 4.2.4 时遇到了类似的问题。

问题是 bundle install devise 作为依赖项安装了另一个版本的 bcrypt (bcrypt (3.1.11 x86-mingw32) 而不是 bcrypt ( 3.1.11)) 导致 ruby​​ 2.3 出现问题(它应该适用于所有以前版本的 ruby​​)

我使用的解决方案是在 gemfile 之外安装 bcrypt，运行 bundle 然后删除 bcrypt 的第二个版本:

$ gem list bcrypt
bcrypt (3.1.11 x86-mingw32)

$ gem uninstall devise && gem uninstall bcrypt
Successfully uninstalled devise-4.2.0
Successfully uninstalled bcrypt-3.1.11-x86-mingw32

$ gem install bcrypt --platform=Ruby

 2. bcrypt-3.1.11-x86-mingw32
 3. All versions
