Question

我有一个使用NgRx和Jest的现有Angular项目。我想将项目转换为对Angular CLI（https://next.angular.io/guide/bazel）使用新的可选的Bazel预览。不幸的是，通过运行ng add @angular/bazel生成的配置无法正确构建我的项目。

这是一个使用Angular Material，NgRx和Jest的Angular 8项目。它是使用nrwl / nx Angular CLI帮助器生成的，因此文件夹结构与标准Angular项目略有不同。我还根据以下说明选择了常春藤：https://angular.io/guide/ivy

我在这里仔细阅读了示例angular + bazel项目：https://github.com/angular/angular-bazel-example 但是，该项目与我的项目不同之处在于，它使用的是Karma + Jasmine，而不是Jest。（我不知道这种差异是否与我的问题有关。）

运行yarn ng add @angular/bazel后，我还运行yarn add parse5来解决此处评论之一所描述的错误：https://github.com/lukasgeiter/gettext-extractor/issues/17

由于nrwl / nx文件夹结构的原因，自动bazel配置对我不起作用（它期望src文件夹位于工作空间的根目录，但我的文件夹位于apps / angularchatclient /下）。通过在我的angular.json文件的多个位置将"targetLabel": "//src:prodapp",更改为"targetLabel": "//apps/angularchatclient/src:prodapp",，我取得了一些进展。我还将--leaveBazelFilesOnDisk选项与ng build一起使用，以便可以将BUILD.bazel文件移动到其正确的目录，并向其中添加应用程序的依赖项。

现在，当我运行yarn build时，出现以下错误：

yarn run v1.16.0
$ ng build

我已经阅读了this related GitHub issue，但是有关更改我的tsconfig规则或为forRoot（）调用声明const变量的建议并没有帮助。另外，this question is related我还缺少什么？

谢谢！

玩笑应该能正常工作，但是我在Angular 8和Bazel中遇到了ngrx相同的错误。尝试将您的angular-metadata.tsconfig.json更新为：

// WORKAROUND https://github.com/angular/angular/issues/18810
//
// This file is required to run ngc on 3rd party libraries such as @ngrx,
// to write files like node_modules/@ngrx/store/store.ngsummary.json.
//
{
    "compilerOptions": {
        "lib": [
            "dom",
            "es2015"
        ],
        "experimentalDecorators": true,
        "types": [],
        "module": "amd",
        "moduleResolution": "node"
    },
    "angularCompilerOptions": {
        "enableSummariesForJit": true
    },
    "include": [
        "node_modules/@angular/**/*",
        "node_modules/@ngrx/**/*"
    ],
    "exclude": [
        "node_modules/@ngrx/store/migrations/**",
        "node_modules/@ngrx/store/schematics/**",
        "node_modules/@ngrx/store/schematics-core/**",
        "node_modules/@angular/cdk/schematics/**",
        "node_modules/@angular/cdk/typings/schematics/**",
        "node_modules/@angular/material/schematics/**",
        "node_modules/@angular/material/typings/schematics/**",
        "node_modules/@angular/common/upgrade*",
        "node_modules/@angular/router/upgrade*",
        "node_modules/@angular/bazel/**",
        "node_modules/@angular/compiler-cli/**",
        "node_modules/@angular/**/testing/**"

    ]
}

我认为这里的关键是导入ngrx模块和enableSummariesForJit。

如何为使用Jest的NgRx项目配置Bazel？
