Bower 和 devDependencies 与依赖项

Question

我运行了“yo Angular”，后来意识到它安装了 1.0.8，我卸载了 Angular 组件，但是当我重新添加所有内容时，原始的 Bower.json 文件在“devDependency”下有 Angular-Mocks 和 Angular-Scenario 1.2.0-rc.2 组件 Angular-Mocks 和 Angular-Scenario 位于依赖项下，而不是 devDependency 下。

我很好奇 devDependency 是如何使用的，以及我是否应该手动修复它或保持原样。有没有办法在 Bower CLI 上指定如何将某些内容标记为开发依赖项？

编辑文件后:

{
    name: "Angular",
    version: "0.0.0",
    dependencies: {
        json3: "~3.2.4",
        jquery: "~1.9.1",
        bootstrap-sass: "~2.3.1",
        es5-shim: "~2.0.8",
        angular-mocks: "1.2.0-rc.2",
        angular-sanitize: "1.2.0-rc.2",
        angular-resource: "1.2.0-rc.2",
        angular-cookies: "1.2.0-rc.2",
        angular: "1.2.0-rc.2",
        angular-scenario: "1.2.0-rc.2"
    },
    devDependencies: { }
}

编辑前:

{
    "name": "Angular",
    "version": "0.0.0",
    "dependencies": {
        "angular": "~1.0.7",
        "json3": "~3.2.4",
        "jquery": "~1.9.1",
        "bootstrap-sass": "~2.3.1",
        "es5-shim": "~2.0.8",
        "angular-resource": "~1.0.7",
        "angular-cookies": "~1.0.7",
        "angular-sanitize": "~1.0.7"
    },
    "devDependencies": {
        "angular-mocks": "~1.0.7",
        "angular-scenario": "~1.0.7"
    }
}

devDependency 用于与开发相关的脚本，例如单元测试、打包脚本、文档生成等

依赖项是生产使用所必需的，并且假设开发也需要。

在依赖项中包含devDependency(如您所拥有的那样)不会有害；该模块只会在安装过程中捆绑更多文件(字节) - 消耗更多(不必要的)资源。从纯粹的观点来看，这些额外的字节可能是有害的，这取决于您的观点。

为了阐明一些情况，请查看 bower help install，在模块安装过程中可以通过 -p 或--生产，例如:

bower install angular-latest --production

这是对除开发平台以外的任何平台执行安装的推荐方法。

相反，无法省略依赖项下列出的模块。

从 bower@1.2.7 开始(请参阅 bower latest source )，bower help 产生:

Usage:

    bower <command> [<args>] [<options>]

Commands:

    cache                   Manage bower cache
    help                    Display help information about Bower
    home                    Opens a package homepage into your favorite browser
    info                    Info of a particular package
    init                    Interactively create a bower.json file
    install                 Install a package locally
    link                    Symlink a package folder
    list                    List local packages
    lookup                  Look up a package URL by name
    prune                   Removes local extraneous packages
    register                Register a package
    search                  Search for a package by name
    update                  Update a local package
    uninstall               Remove a local package

Options:

    -f, --force             Makes various commands more forceful
    -j, --json              Output consumable JSON
    -l, --log-level         What level of logs to report
    -o, --offline           Do not hit the network
    -q, --quiet             Only output important information
    -s, --silent            Do not output anything, besides errors
    -V, --verbose           Makes output more verbose
    --allow-root            Allows running commands as root

See 'bower help <command>' for more information on a specific command.

此外，bower help install 会产生(请参阅 latest source ):

Usage:

    bower install [<options>]
    bower install <endpoint> [<endpoint> ..] [<options>]

Options:

    -F, --force-latest      Force latest version on conflict
    -h, --help              Show this help message
    -p, --production        Do not install project devDependencies
    -S, --save              Save installed packages into the project's bower.json dependencies
    -D, --save-dev          Save installed packages into the project's bower.json devDependencies

    Additionally all global options listed in 'bower help' are available

Description:

    Installs the project dependencies or a specific set of endpoints.
    Endpoints can have multiple forms:
    - <source>
    - <source>#<target>
    - <name>=<source>#<target>

    Where:
    - <source> is a package URL, physical location or registry name
    - <target> is a valid range, commit, branch, etc.
    - <name> is the name it should have locally.
