鲍尔和devDependencies vs依赖
我运行了'哟angular'，然后意识到它安装了1.0.8，我卸载了angular度组件，但是当我重新添加所有1.2时，原始的bower.json文件在'devDependencies'下有angular-mock和angular-scenario。 0-rc.2组件的angular度嘲笑和angular情景依赖关系，而不是devDependencies。
我很好奇devDependencies是如何使用的，如果我应该打扰手动修复它或保持原样。 有没有一种方法可以在bower CLI上指定如何将某些东西标记为开发依赖项？
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: { } } 编辑之前：
{ "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" } }
devDependencies是与开发相关的脚本，例如unit testing，打包脚本，文档生成等。
生产使用需要dependencies ，并且假定dev也需要dependencies 。
包括dependencies devDependencies ，就像你一样，不会有害的; 该模块将在安装过程中捆绑更多的文件（字节） – 消耗更多（不必要）的资源。 从纯粹的POV，这些额外的字节可能是有害的，只是取决于你的观点。
为了说明一下，在bower help install ， devDependencies出的模块可以在模块安装时通过-p或--production省略，例如：
bower install angular-latest --production
对于开发平台以外的任何其他应用程序，这是推荐的方法。
相反，无法省略dependencies模块。
如bower@1.2.7 （见鲍尔最新消息 ）， bower help产量：
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.
并进一步， bower help install产量（见最新来源 ）：
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.
