针对特定软件包版本的pip依赖树

Question

我想查看特定软件包所需的所有依赖项（在这种情况下，我使用pipdeptree），但事实证明它仅向我显示已安装软件包的依赖树。 假设我正在使用graphene: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]
------------------------------------------------------------------------

现在当我尝试执行 $ pipdeptree -p graphene==40.0.2 （该版本不存在）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]
------------------------------------------------------------------------

看起来它只考虑了稳定版本，我想要的是一个与我在控制台中指定的特定版本相关的依赖树，希望我表达清楚了。

我相信johnnydep可以帮助解决这个问题：

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