特定软件包版本的 pip 依赖树

Question

我正在尝试查看特定包所需的所有依赖项（在本例中我使用 pipdeptree），但事实证明它只显示了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（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]
------------------------------------------------------------------------

似乎它只考虑了一个稳定的版本，我想要的是一个与我通过控制台提供的特定版本相关的依赖树，我希望我对此很清楚。

我相信johnnydep 可以提供帮助：

$ johnnydep --verbose 0 'graphene==2.1.0'
name                            summary
