gem＆＃39; bcrypt＆＃39;，＆＃39;〜＆gt; 3.1.11＆＃39;＆＃34;

Question

我在Windows 7 64位，我正在运行Ruby 2.3.3和Rails 5.1.2。在尝试在我的网站上创建新用户时，我遇到了我的RoR项目的错误：

＆＃34; Devise中的LoadError :: RegistrationsController #create＆＃34; ＆＃34;无法加载这样的文件--bcrypt_ext＆＃34;

我通过Google搜索找到了这个和类似的解决方案：

＆＃34;首先通过运行这两个来卸载bcrypt和bcrypt-ruby 命令：gem uninstall bcrypt和gem uninstall bcrypt-ruby安装再次使用gem install bcrypt --platform = ruby在你的Gemfile中写一下 gem＆＃39; bcrypt-ruby＆＃39;，＆＃39; 3.1.5＆＃39;，：require =＆gt; ＆＃39; bcrypt＆＃39;运行bundle install＆＃34;

但是，当我尝试在我的控制台中运行gem uninstall bcrypt时，我收到以下错误消息：

＆＃34; $ gem uninstall bcrypt错误：执行gem时...... （宝石:: DependencyRemovalException）由于依赖gem（s）＆＃34;
，卸载中止

我相信这是由于我的Devise宝石。当我在控制台中运行gem list bcrypt时，我会收到此输出：

＆＃34; bcrypt（3.1.11 x86-mingw32）＆＃34;

我的rails应用程序附带了我的gem文件中注释掉的这一行：

＆＃34;＃使用ActiveModel has_secure_password

gem＆＃39; bcrypt＆＃39;，＆＃39;〜＆gt; 3.1.11＆＃39;＆＃34;

我已经尝试将其取消注释回代码，当我这样做时，Rails服务器无法加载并在控制台中列出此错误：

此时，我没有想法。请指教。谢谢。

Answer 1

在卸载bcrypt-ruby之前，您应该卸载bcrypt，因为这是依赖的gem。

这可以这样做：

gem uninstall bcrypt-ruby
gem uninstall bcrypt
gem install bcrypt --platform=ruby

Answer 2

尝试以下适用于我的步骤：

从您的Gemfile中删除与brypt相关的任何内容
在Gemfile中输入以下信息

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

在项目的根目录运行'bundle install'，它应该可以正常工作。

出于某种原因，当你将它指向git页面时，它对我有效。
