You'll need to explicitly specify the B gem in your Gemfile to use a git repository or another version. As long as A 1.0.0 is compatible with B 1.0.1 you'll be fine. If it is only compatible with B 1.0.0 then you'll have to create your own fork of the A gem and upgrade the gemspec to be compatible with B 1.0.1 and then use that repository as your gem for A instead of the rubygems version.

您需要在Gemfile中明确指定B gem以使用git存储库或其他版本。只要A 1.0.0与B 1.0.1兼容，你就可以了。如果它只与B 1.0.0兼容，那么你将不得不创建自己的A gem的分支并升级gemspec以与B 1.0.1兼容，然后使用该存储库作为A的宝石而不是rubygems版。

Here is a sample Gemfile that should give you what you want, provided A 1.0.0 is compatible with B 1.0.1.

这是一个示例Gemfile，可以为您提供所需的内容，前提是A 1.0.0与B 1.0.1兼容。

gem 'B', :git => 'git://github.com/B/B.git', :tag => '1.0.1'
gem 'A', '~> 1.0.0'
