我可以在gemfile中强制创建一个gem的依赖关系吗? [英] Can I force a gem's dependencies in gemfile?
问题描述
如果有两个宝石, A
和 B
。 A1.0.0
取决于 B1.0.0
。
在我的Gemfile中:
gem'A','〜> 1.0.0'
然后运行 bundle
。它会生成一个Gemfile.lock,如下所示:
A(1.0.0)
B(1.0.0)
但是如果我想强制 A
来使用 B1.0.1
,最佳做法是什么?此外,如果 B1.0.1
不是释放而是一个github标签?
您需要在您的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。如果它仅与B 1.0.0兼容,那么您将不得不创建自己的A gem分支,并将gemspec升级为与B 1.0.1兼容,然后将该存储库用作A的宝石,而不是rubygems版本。
如果A 1.0.0与B 1.0.1兼容,以下是一个示例Gemfile,它应该为您提供所需内容。
gem'B',::git => 'git://github.com/B/B.git',:tag => '1.0.1'
gem'A','〜> 1.0.0'
If there are two gems, A
and B
. A1.0.0
depends on B1.0.0
.
In my Gemfile:
gem 'A', '~> 1.0.0'
Then run bundle
. It will generate a Gemfile.lock like:
A (1.0.0)
B (1.0.0)
But if I want to force A
to use B1.0.1
, what's the best practice? Moreover, if the B1.0.1
is not release but a github tag?
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.
Here is a sample Gemfile that should give you what you want, provided A 1.0.0 is compatible with B 1.0.1.
gem 'B', :git => 'git://github.com/B/B.git', :tag => '1.0.1'
gem 'A', '~> 1.0.0'
