在项目“ my-lib”中找不到配置“生产” [英] Configuration 'production' could not be found in project 'my-lib'

问题描述

我正在使用Angular 6.1.0构建库

I am building a library with Angular 6.1.0

• ng新lib-demo


• ng生成库my-lib

• ng new lib-demo
• ng generate library my-lib

所有文章都建议使用-prod 标志运行库的构建，如下所示：

All the articles advise running the build for the library with a --prod flag like so:

ng build my-lib --prod

但是，这会引发错误

Configuration 'production' could not be found in project 'my-lib'.

这可能是正确的，因为当我查看 angular.json 时，在库项目中没有定义生产构建配置。它仅适用于应用程序项目。

Which is probably correct because when I look at the angular.json there is no definition for a production build configuration in the library project. It is present for the application project only.

以下是我在使用 ng-packagr

"build": {
      "builder": "@angular-devkit/build-ng-packagr:build",
      "options": {
        "tsConfig": "projects/my-lib/tsconfig.lib.json",
        "project": "projects/my-lib/ng-package.json"
      }
    }

所以这里的问题是-prod 标志不再需要，仅运行 ng build m-lib 会生成prod版本吗？

So the question here is that is the --prod flag not required anymore and just running ng build m-lib will generate a prod build?

看着dist文件夹的内容看起来是这样，但我不确定100％。如果有人可以验证这一点，那就太好了。

Looking at the contents of dist folder it looks so but I am not 100% sure. If someone could validate this, it will be great.

推荐答案

从6.1版开始，Angular始终对我们的库进行生产构建，即在新版本的Angular中，构建它时不再需要-prod 标志，库始终以AOT模式构建。为了确保这一点，您可以在Angular-CLI存储库中查看以下问题：

Beginning with version 6.1, Angular always does a production build of our library, i.e. in new versions of Angular we don't need the --prod flag anymore when building it, libraries are always built in AOT mode. To ensure, you can take a look at these issues in Angular-CLI repository:

https://github.com/angular/angular-cli/issues/12290

https://github.com/angular/angular-cli/issues/12226

而本文（构建库 部分）：

如果您仍在使用6.0.x版（或更低版本），则需要使用-

If you are still using version 6.0.x (or lower) you will want to use the --prod flag when building your library.

您仍然可以选择通过配置作为参数（如果需要）： ng build --configuration = configuration （请参见文档）。如有必要，您可以在 angular.json 中指定生成规则，例如，对于 production build：

You still have an option to pass a configuration as a parameter if needed: ng build --configuration=configuration (see docs). If necessary, you can specify build rules in angular.json, for example, for production build:

"configurations": {
    "production": {
        // Options here
    }
}

命令应为 ng build --configuration = production 。
