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（在这种情况下，我使用的是 pipdeptree），但事实证明它只向我显示了已安装包的依赖项树。假设我正在使用石墨烯：2.1.0，例如：$ pipdeptree -p grapheneWarning!!! 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]------------------------------------------------------------------------现在当我尝试时$ pipdeptree -p graphene==40.0.2 （不存在）。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'
