特定包版本的pip依赖关系树

Question

我试图查看特定包所需的所有依赖项（在本例中，我使用的是pipdeptree），但结果表明，它只显示已安装包的依赖项树。假设我使用的是石墨烯：2.1.0，例如：

$ pipdeptree -p graphene

Warning!!! Possibly conflicting dependencies found:
* graphql-relay==0.5.0
 - graphql-core [required: >=0.5.0,<2, installed: 2.3.1]
* social-auth-core==3.2.0
 - requests [required: >=2.9.1, installed: 2.8.1]
------------------------------------------------------------------------

现在，当我尝试$ pipdeptree -p graphene==40.0.2（它不存在）时

Warning!!! Possibly conflicting dependencies found:
* graphql-relay==0.5.0
 - graphql-core [required: >=0.5.0,<2, installed: 2.3.1]
* social-auth-core==3.2.0
 - requests [required: >=2.9.1, installed: 2.8.1]
------------------------------------------------------------------------

它似乎只考虑了一个稳定的版本，我想要的是一个依赖关系树，它与我通过控制台提供的特定版本相关，我希望我已经清楚了这一点

我相信johnnydep可以帮助做到这一点：

$ johnnydep  verbose 0 'graphene==2.1.0'
