我从https://github.com/mhartl/rails_tutorial_3rd_edition_gemfiles/blob/master/sample_app/Gemfile获得了宝石

然后我收到一条错误消息，例如

这个问题是 Windows 特有的，在bcrypt-ruby issue: 72中得到解决。

更新你Gemfile为：

gem 'bcrypt-ruby', '3.1.1.rc1', :require => 'bcrypt'

然后

bundle install

只需按照此链接的步骤操作：这对我 有用 https://www.ambidev.com/loaderror-cannot-load-such-file-bcrypt_ext/

您应该正确安装和配置 DevKit 以重新编译 gem。

LoadError: cannot load such file -- bcrypt_ext

首先停止您的服务器并删除每个 bcrypt gem 或 bcrypt-ruby gem。

C:\>gem uninstall bcrypt
You have requested to uninstall the gem:
    bcrypt-3.1.10-x86-mingw32

bcrypt-ruby-3.1.5 depends on bcrypt (>= 3.1.3)
devise-3.5.2 depends on bcrypt (~> 3.0)
If you remove this gem, these dependencies will not be met.
Continue with Uninstall? [yN]  y
Successfully uninstalled bcrypt-3.1.10-x86-mingw32

不要忘记在您的 Gemfile gem 'bcrypt' 中包含 bcrypt

进行捆绑更新并像这样重新编译gem

C:\<Ruby Path>\lib\ruby\gems\bcrypt-3.1.10-x86-mingw32\ext\mri> ruby 
extconf.rb
C:\<Ruby Path>\lib\ruby\gems\bcrypt-3.1.10-x86-mingw32\ext\mri> make
generating bcrypt_ext-i386-mingw32.def
compiling bcrypt_ext.c
compiling crypt.c
compiling crypt_blowfish.c
compiling crypt_gensalt.c
compiling wrapper.c
linking shared-object bcrypt_ext.so

(if make is not recognized as a valid command, execute this command and do a 
make again
C:\<Current Folder> C:\<DevKit Path>\devkitvars.bat
Adding the DevKit to PATH...)

C:\<Ruby Path>\lib\ruby\gems\bcrypt-3.1.10-x86-mingw32\ext\mri> make install
/usr/bin/install -c -m 0755 bcrypt_ext.so /C/<Ruby 
Path>/lib/ruby/site_ruby/2.2.0/i386-msvcrt

重新启动您的服务器。

它应该可以解决问题！

阅读GitHub 上的问题#72、#102和116 ！

更新你Gemfile！将此添加到您的Gemfile：

gem 'bcrypt', '3.1.9'

注意！：bcrypt-ruby宝石已将其名称更改为bcrypt. 而不是 安装bcrypt-ruby，你应该安装bcrypt。请相应地更新您的依赖项。

然后在 CMD 中运行命令：

bundle

或者

bundle install

该错误已在 3.1.9 版本中修复。不要使用旧版本的 bcrypt！
