Bower和devDependencies与依赖关系
我运行了'yo angular'并且后来意识到它安装了1.0.8，我卸载了角度组件，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-mocks和angular-scenario。 0-rc.2组件的角度嘲笑和角度情景下的依赖关系，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，例如单元测试，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 ，就像你拥有它一样，不会有害; 该模块将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POV，这些额外的字节可能是有害的，只取决于你的观点。
为了说明一下，看看bower help install ，在模块安装过程中，通过-p或--production可以省略devDependencies出的模块，例如：
bower install angular-latest --production
对于开发平台以外的任何其他应用程序，这是推荐的安装方式。
相反，无法省略dependencies模块。

- <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.
