ruby-on-rails - 找不到 bcrypt-3.1.11 的错误

Question

我使用设备 gem 创建了一个应用程序，然后运行 ​​bundle instal。

比我尝试运行这个命令之后

rails generate devise:install

但是我得到了错误

Could not find bcrypt-3.1.11 in any of the sources
Run `bundle install` to install missing gem...

我做了 bundle install

我试过这个 gem install bcrypt 来安装这个 gem

我尝试捆绑更新然后运行

bundle exec rails generate devise:install

但我仍然遇到同样的错误。
