Angular 示意图 : trustedSubscriber. _addParentTeardownLogic

Question

我正在尝试构建 Angular Schematics 来帮助我和我的团队快速创建 NgRx 操作。这是原理图功能，大部分是从各种教程中复制过来的:

export default (options: CCSchematicsAction): Rule => {
    return (tree: Tree, _context: SchematicContext) => {
        const modulePath = options.modulePath.replace(/-?module$/, ""); // "shared/application-tools"
        const moduleFolder = normalize("src/app/" + modulePath); // "src/app/shared/application-tools"
        const modulePathComponents = modulePath.split("/"); // ["shared", "application-tools"]
        const moduleIdentifier = modulePathComponents
            .map(part => classify(part))
            .join(".")
        + ".Action"; // "Shared.ApplicationTools.Action"

        const action = options.name.replace(/-?action$/, "");
        const path = normalize(moduleFolder + "/action/" + action) + "/";

        const templateSource = apply(url("./files"), [
            template({
                action: action,
                moduleIdentifier: moduleIdentifier
            }),
            move(path)
        ]);

        return chain([
            mergeWith(templateSource)
        ])(tree, _context);
    };
}

我调用原理图

schematics cc-generate:action load-stuff-action --modulePath shared/ui

并获得以下内容，我什至无法在网上找到任何信息:

    at DoOperator.call (/usr/local/lib/node_modules/@angular-devkit/schematics-cli/node_modules/rxjs/internal/operators/tap.js:29:23)

编辑:

当我删除所有内容并只返回一个空链时，错误仍然存​​在。

export default (_options: CCSchematicsAction): Rule => {
    return (tree: Tree, _context: SchematicContext) => {
        return chain([noop()])(tree, _context);
    };
}

那么 chain 函数有什么问题呢？

没关系，问题是 @angular-devkit/schematics-cli 的不同版本..
