Question

我有 ruby​​ 2.3.3p222（2016-11-21 修订版 56859）[x64-mingw32] 和 rails 5.1.4。运行rails s 命令时出现以下错误。

rails s

我几乎尝试了所有解决方案，但我无法解决这个问题。任何机构都可以帮我解决这个问题。我已经尝试过：

首先通过运行以下两个命令卸载 bcrypt 和 bcrypt-ruby： gem 卸载 bcrypt 和 gem 卸载 bcrypt-ruby 使用 gem install bcrypt --platform=ruby 再次安装 在你的 Gemfile 中写 gem 'bcrypt-ruby', '3.1.5', :require => 'bcrypt' 运行捆绑安装

Answer 1

我已经设法通过在 Gemfile 中添加以下行来解决这个问题....

gem 'bcrypt', git: 'https://github.com/codahale/bcrypt-ruby.git', :require => 'bcrypt'

Answer 2

在尝试了几种方法后，以上方法对我有用： 1) 停止所有 rails 服务器。 2) 添加：gem 'bcrypt', git: 'https://github.com/codahale/bcrypt-ruby.git', :require => 'bcrypt' 到 gemfile。 3) 捆绑安装。
