如何用插件包抓取python包？

Question

我想捆绑Python包kedro，它提供了一个命令行界面(kedro)。此外，我还想把Python包kedro-docker放到快照中。第二个包扩展了第一个包的命令行界面(kedro docker)。但是当我使用下面的snapcraft.yaml创建快照时，我只得到了第一个包的命令行界面：

name: kedro
base: core18
version: latest
description: |
    Kedro is a development workflow framework that implements software
    engineering best-practice for data pipelines with an eye towards
    productionising machine learning models.

grade: devel
confinement: devmode

architectures:
  - build-on: [amd64]

apps:
  kedro:
    command: kedro
    plugs:
      - home
      - network
      - network-bind
      - docker
    environment: {
      LANG: C.UTF-8,
      LC_ALL: C.UTF-8
    }

parts:
  kedro:
    plugin: python
    python-version: python3
    python-packages:
      - kedro==0.15.9
      - kedro-docker==0.1.1

如何将扩展命令行界面(kedro docker)添加到快照中？

我不是专家，也从未使用过snapcraft，因此这里只是一个假设。Kedro-Docker只公开特定于项目的命令，除非您位于项目的根目录中，否则这些命令不会出现。因此，如果先运行kedro new，然后运行cd <project-dir> && kedro，您应该(理想情况下)会看到一组docker命令：

Global commands from Kedro
Commands:
  docs  See the kedro API docs and introductory tutorial.
  info  Get more information about kedro.
  new   Create a new kedro project.

Project specific commands from Docker
Commands:
  docker  Dockerize your Kedro project.
