捆绑安装错误；积极支持

Question

捆绑过程中似乎出现了一些错误！ bundle install

后似乎出现以下消息

C:\Users\Nir\Desktop\my projects\projectmeal>bundle install

    Bundler could not find compatible versions for gem "activesupport":
      In snapshot (Gemfile.lock):
        activesupport (= 5.0.0.1)

      In Gemfile:
        carrierwave x86-mingw32 was resolved to 0.11.2, which depends on
          activesupport (>= 3.2.0) x86-mingw32

    easy_rails_money (~> 0.0.8) x86-mingw32 was resolved to 0.0.8, which depends
    on

        elasticsearch-model x86-mingw32 was resolved to 0.1.9, which depends on

        rspec-rails x86-mingw32 was resolved to 3.5.2, which depends on
          activesupport (>= 3.0) x86-mingw32

    Running `bundle update` will rebuild your snapshot from scratch, using only
    the gems in your Gemfile, which may resolve the conflict.

当我尝试运行诸如 rake db:create 之类的 rails 命令时，在终端中会出现以下错误

C:\Users\Nir\Desktop\my projects\projectmeal>rake db:create
Could not find gem 'guard-rspec x86-mingw32' in any of the gem sources listed in
 your Gemfile or available on this machine.
Run `bundle install` to install missing gems.

这个过程还在继续.....

如果 bundle 说它找不到兼容的 gem 版本，那可能是因为它无处可寻。您正在给它版本号，即强制它为每个 gem 采用某些版本，或者优于 X 或低于 X 的版本。

而不是：

  gem 'activesupport'

试试：

gem 'activesupport', '3.2.0'
