角度 v 4.0.0 中的对等依赖警告

Question

我已将 Angular 包版本从 2.4.10 更新到 4.0.0。运行“npm install”命令后，它会抛出以下消息

    npm ERR! peer dep missing: @angular/common@^2.3.0, required by @angular/material@2.0.0-beta.2
    npm ERR! peer dep missing: @angular/common@^2.0.0, required by angular2-flex@1.0.3
    npm ERR! peer dep missing: @angular/core@^2.3.0, required by @angular/material@2.0.0-beta.2
    npm ERR! peer dep missing: @angular/core@^2.0.0, required by angular2-flex@1.0.3

我的安装包列表如下

"dependencies": {
    "@angular/common": "^4.0.0",
    "@angular/compiler": "^4.0.0",
    "@angular/core": "^4.0.0",
    "@angular/forms": "^4.0.0",
    "@angular/http": "^4.0.0",
    "@angular/material": "^2.0.0-beta.2",
    "@angular/platform-browser": "^4.0.0",
    "@angular/platform-browser-dynamic": "^4.0.0",
    "@angular/router": "^4.0.0",
    "angular2-moment": "^1.3.0",
    "angular2-recaptcha": "^0.4.0",
    "angular2-flex": "^1.0.3"
}

并且在 webpack.common.js 中改变了配置

new webpack.ContextReplacementPlugin(
            // The (\\|\/) piece accounts for path separators in *nix and Windows
            /angular(\\|\/)core(\\|\/)@angular/,
            helpers.root('./src'),// location of your src
            {} // a map of your routes
        )

Answer 1

@angular/material 包需要 angular 2，因此它与 angular 4 不兼容。semantic versioning rules of npm，^2.3.0 只允许大于或等于 2.3.0 的版本，但仍与主要版本 2，所以只有2.x.y 其中x >= 3。

您必须等到他们发布 Angular 4 版本。合并拉取请求 #3752 时，您可以使用 Readme - Installation 中所述的主分支。否则，您需要等到他们将其发布到 npm。
