我正在尝试通过将 unity-tweak-tool 重新打包为 snap 来学习 snap 桌面打包的一些知识。我发现文档不太好,但到目前为止,我有一个 snapcraft.yaml 文件,如下所示:
name: unity-tweak-tool
version: 1
summary: configuration tool for the Unity desktop environment
description: |
Unity Tweak Tool is a settings manager for the Unity desktop.
It provides users with a fast, simple and easy-to-use interface
with which to access many useful and little known features and settings
of the desktop environment that one may want to configure.
apps:
unity-tweak-tool:
command: $SNAP/usr/bin/unity-tweak-tool
plugs: [unity7]
parts:
unity-tweak-tool:
plugin: python3
source: git://github.com/Seth-Johnson/unity-tweak-tool.git
source-type: git
build-packages:
- python3-distutils-extra
- python3-all
- python3-dbus
- python-dev
stage-packages:
- gir1.2-glib-2.0
- gir1.2-gtk-3.0
- python3-xdg
- python3-cairo
- unity-webapps-service
但是,当我运行snapcraft snap
setup.py时总是失败,因为缺少几个python模块:
Running setup.py install for unity-tweak-tool ... error
Complete output from command /home/sethj/projects/snappy-testing/parts/unity-tweak-tool/install/usr/bin/python3 -u -c "import setuptools, tokenize;__file__='/tmp/pip-s6dwhgys-build/setup.py';exec(compile(getattr(tokenize, 'open', open)(__file__).read().replace('\r\n', '\n'), __file__, 'exec'))" install --record /tmp/pip-xxv1mi7p-record/install-record.txt --single-version-externally-managed --compile --home=/tmp/tmp2y5izah7:

(全输出这里)
我承认我不是 100% 确定我做得正确,但据我所知,它应该构建 build-packages 下列出的包,以满足 unity-tweak-tool 的构建要求。
我哪里做错了?
答案1
对于 python 来说,您可能希望其中一些build-packages
是stage-packages
。python 插件设置PYTHONPATH
为在 snap 中,这就是它缺少这些包的原因(您已将它们安装在主机系统上)。
顺便说一句,如果这个上游有适当的install_requires
这些setup.py
依赖关系,就会自动为您处理。
