Ruby on rails ruby on rails，由于bcrypt_ext（LoadError），运行服务器不工作

我从他那里得到了宝石

然后我收到一条错误消息，如

此问题是特定于Windows的，在中解决

将您的文件更新为：

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

然后

阅读问题，并在GitHub上阅读

---

更新您的Gemfile！将此添加到您的

GEM文件中

：

gem 'bcrypt', '3.1.9'

当心！：bcrypt-ruby

gem已将其名称更改为just
bcrypt
。而不是
安装
bcrypt-ruby
，您应该安装
bcrypt
。请更新您的
相应地，依赖关系


然后在CMD中运行命令：

bundle

或


该错误已在3.1.9版中修复。请勿使用bcrypt的旧版本

只需按照此链接的步骤进行操作：
这对我有用

您应该已正确安装和配置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所有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

别忘了在GEM文件中包含bcrypt
宝石“bcrypt”

进行捆绑包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

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

C:\\lib\ruby\gems\bcrypt-3.1.10-x86-mingw32\ext\mri>ruby

C:\\lib\ruby\gems\bcrypt-3.1.10-x86-mingw32\ext\mri>make
生成bcrypt_ext-i386-mingw32.def
编译bcrypt_ext.c
编译crypt.c
编译crypt_blowfish.c
编译crypt_gensalt.c
编译wrapper.c
链接共享对象bcrypt_ext.so
（如果make未被识别为有效命令，请执行此命令并执行以下操作：
重做
C:\C:\\devkitvars.bat
正在将DevKit添加到路径…）
C:\\lib\ruby\gems\bcrypt-3.1.10-x86-mingw32\ext\mri>make-install
/usr/bin/install-c-m 0755 bcrypt_ext.so/c//lib/ruby/site_ruby/2.2.0/i386-msvcrt

重新启动服务器

它应该会成功的
 您是否安装了
bundle
？是的，但仍然错误输出
bundle show bcrypt
？错误是rails服务器的输出，我添加了bcrypt并运行了bundle install show me输出
bundle show bcrypt
我是否需要用您编写的代码替换“gem'bcrypt'，'3.1.7'？我只是在前面添加了它们是的，你需要替换。请发布代码而不是链接，因为链接将来可能会更改。
