带有模块的Snapcraft python脚本，暂存问题

Question

我正在构建一个snap来测试python脚本和python与管理技术的集成，当两个python‘部件’构建在同一个快照中时，就会出现冲突。

使用多个python模块构建snap的最佳方法是什么？

我有一个简单的脚本，它导入SDK，然后打印一些信息。我还将python库(https://help.iotconnect.io/documentation/sdk-reference/device-sdks-flavors/download-python-sdk/)放在另一个文件夹中。

我已经定义了这两个部分，每个部分都可以单独构建(快照构建PARTNAME)，但是在下一步将它们“分阶段”时，python内部似乎是相互冲突的。

运行‘快照’显示了大量的错误，这些错误看起来像是与python内部相关的两个“部分”之间的冲突。

... Tons more removed

Snapcraft offers some capabilities to solve this by use of the following keywords:
    - `filesets`
    - `stage`
    - `snap`
    - `organize`

To learn more about these part keywords, run `snapcraft help plugins`.
Run the same command again with --debug to shell into the environment if you wish to introspect this failure.

主要问题，使用多个python模块构建一个snap的最好方法是什么？

Answer 1

为了使解决方案更可移植，并处理不同的版本号，子文件夹可以使用通配符。

lib-pythonsdk:
    plugin: python
    source: ./iotconnect-sdk-3.0.1/
    stage:
      - -lib/python3.8/site-packages/pip*
      - -lib/python3.8/site-packages/wheel*
      - -lib/python3.8/site-packages/setuptools/
      - -lib/python3.8/site-packages/_distutils_hack
      - -lib/python3.8/site-packages/pkg_resources
      - -bin/activate
      - -bin/activate.csh
      - -bin/activate.fish
      - -pyvenv.cfg

Answer 2

看起来最好的解决方案是从库中删除违规的构建文件。“lib-basictest”部分是主要的执行脚本，其中生成的文件应该包含在SDK库版本中。

下面是更新的lib-pythonsdk部分

  lib-pythonsdk:
    plugin: python
    source: ./iotconnect-sdk-3.0.1/
    stage:
      - -lib/python3.8/site-packages/pip/
      - -lib/python3.8/site-packages/setuptools/
      - -lib/python3.8/site-packages/wheel/
      - -lib/python3.8/site-packages/_distutils_hack
      - -lib/python3.8/site-packages/pip-21.3.1.dist-info
      - -lib/python3.8/site-packages/pkg_resources
      - -lib/python3.8/site-packages/wheel-0.37.1.dist-info
      - -bin/activate
      - -bin/activate.csh
      - -bin/activate.fish
      - -pyvenv.cfg

这就是我要做的事情，除非我遗漏了一些“覆盖”参数？
