Snapcraft 指南 (Linux)

    与更广泛的 Linux 社区一起, 规范旨在解决 项目中的许多常见的软件安装问题。 Snaps 是容器化的软件包, 包括所需的依赖项、自动更新和对所有主要 Linux 发行版的工作, 而无需进行系统修改。

    创建 .snap 文件有三种方法:

    1) Using Electron Forge or , both tools that come with snap support out of the box. 这是最简单的选择。 2) 使用 electron-installer-snap, 它采用 electron-packager 的输出。 3) 使用已经创建的 .deb 包。

    在某些情况下，您需要安装 snapcraft 工具。 安装特定发行版的 snapcraft 的指南在这里能看到。

    Package the application using (or a similar tool). Make sure to remove node_modules that you don’t need in your final application, since any module you don’t actually need will increase your application’s size.

    结构输出应该看起来大致像这样:

    1. .
    2. └── dist
    3.     └── app-linux-x64
    4.         ├── LICENSE
    5.         ├── LICENSES.chromium.html
    6.         ├── content_shell.pak
    7.         ├── app
    8.         ├── icudtl.dat
    9.         ├── libgcrypt.so.11
    10.         ├── libnode.so
    11.         ├── locales
    12.         ├── resources
    13.         ├── v8_context_snapshot.bin
    14.         └── version

    步骤 2: 运行 electron-installer-snap

    From a terminal that has snapcraft in its PATH, run electron-installer-snap with the only required parameter --src, which is the location of your packaged Electron application created in the first step.

    1. npx electron-installer-snap --src=out/myappname-linux-x64

    If you have an existing build pipeline, you can use electron-installer-snap programmatically. For more information, see the .

    1. name: electron-packager-hello-world
    2. version: '0.1'
    3. summary: Hello World Electron app

    19.       # libappindicator has readable resources.
    20.       TMPDIR: $XDG_RUNTIME_DIR

    26.     override-build: |
    27.         npm install electron electron-packager
    28.         npx electron-packager . --overwrite --platform=linux --output=release-build --prune=true
    29.         cp -rv ./electron-quick-start-linux-* $SNAPCRAFT_PART_INSTALL/electron-quick-start
    30.     build-snaps:
    31.     - node/14/stable
    32.     build-packages:
    33.     - unzip
    34.     stage-packages:
    35.     - libnss3
    36.     - libnspr4

    如果要将此示例应用于现有项目：

    • 替代 source: https://github.com/electron/electron-quick-start.git</0 > 为 <code>source: ...
    • 替代所有的 electron-quick-start 为你的项目名称。

    第 2 步：构建 snap

    1. $ snapcraft
    3. <output snipped>
    4. Snapped electron-packager-hello-world_0.1_amd64.snap

    第 4 步：运行 snap

    1. electron-packager-hello-world

    Snapcraft is capable of taking an existing .deb file and turning it into a .snap file. The creation of a snap is configured using a snapcraft.yaml file that describes the sources, dependencies, description, and other core building blocks.

    If you do not already have a .deb package, using electron-installer-snap might be an easier path to create snap packages. However, multiple solutions for creating Debian packages exist, including , electron-builder or .

    步骤 2: 创建一个 snapcraft.yaml

    For more information on the available configuration options, see the . Let’s look at an example:

    1. name: myApp
    2. version: '2.0.0'
    3. summary: A little description for the app.

    28.     source: files/
    29.     prepare: |
    30.       chmod +x bin/electron-launch
    32. apps:
    33.   myApp:
    34.     command: bin/electron-launch $SNAP/usr/lib/myApp/myApp
    35.     desktop: usr/share/applications/myApp.desktop
    36.     # Correct the TMPDIR path for Chromium Framework/Electron to ensure
    37.     # libappindicator has readable resources.
    38.     environment:
    39.       TMPDIR: $XDG_RUNTIME_DIR

    Alternatively, if you’re building your snap with strict confinement, you can use the desktop-launch command:

    1. apps:
    2.   myApp:
    3.     # Correct the TMPDIR path for Chromium Framework/Electron to ensure
    4.     # libappindicator has readable resources.
