angular - 如何使用 Angular CLI 7.0.0-RC2 正确创建库项目

Question

:) 我使用yarn全局安装了@angular/cli@next，以便创建一个Angular7项目。

我正在尝试创建一个库项目来添加我编写的几个库，我想在多个项目中使用这些库。

我使用命令 ng new tuxin-libs --style=scss --experimental-ivy 创建了库项目，并在添加路由时键入 No 因为它将是只是一个图书馆项目。

然后我输入 tuxin-libs 并使用 nggeneratelibrary cars --prefix=tuxin 创建了一个库，并创建了一个名为 car-type 的组件code> 与 ng 生成组件 car-type --project=cars

我不需要主要的 cars 组件，因此删除了 cars.component.ts 和 cars.component.spec.ts 文件 并从 public_api.ts 中删除了 export * from './lib/cars.component'; 并添加了我的代码。

现在我使用@angular/material、apollo-angular和ngx-webstorage-service。我真的很困惑如何将它添加到我的图书馆项目

有人说将其添加为对等依赖项。所以我输入了 projects/cars 并尝试使用以下命令将这些库安装为对等依赖项:

yarn add --peer @angular/material @angular/cdk @angular/animations
yarn add --peer apollo-angular   apollo-angular-link-http   apollo-link   apollo-client   apollo-cache-inmemory   graphql-tag   graphql
yarn add --peer ngx-webstorage-service

然后，当我尝试通过进入库项目的根目录并执行 ng build cars 来构建 cars 模块时，我得到了

当我尝试将其添加为常规依赖项时，使用与之前相同的 yarn 命令，只是没有 --peer 参数，然后尝试编译 cars 库得到:

使用 Angular6 cli 而不是最新的 Angular7 时发生的错误完全相同...但无论如何..现在我使用的是 7，所以我希望它在这里得到修复:)

我还尝试使用 ng add @angular/material --project=cars 和 ng add apollo-angular --project=cars，在这两种情况下我都得到 定义了多个项目；请指定项目名称，尽管我确实指定了项目。

有什么想法吗？

任何有关此问题的信息将不胜感激。

谢谢!

Answer 1

好的..所以我需要在 cars 项目的 package.json 中添加相关库作为对等依赖项，并将其作为常规依赖项添加到主库项目中。

就是这样:)简单
