Angular 角度9（没有常春藤）如何从ViewContainerRef获取_视图？

我有一个项目（几天前还在工作），它使用angular 9而不使用常春藤

tsconfig

{
    "angularCompilerOptions": {
        "enableIvy": false,
    },
"compilerOptions": {
        "downlevelIteration": true,
        "target": "es2015",
        "module": "esnext",
        "moduleResolution": "Node",
        "sourceMap": true,
        "emitDecoratorMetadata": true,
        "experimentalDecorators": true,
        "lib": [
            "es2018",
            "dom"
        ],
        "noImplicitAny": true,
        "suppressImplicitAnyIndexErrors": true,
        "outDir": "dist",
        "types": [
            "node"
        ],
        "typeRoots": [
            "node_modules/@types"
        ]
    },
    
}

我的指令

export class SomeDirective {


    constructor(viewContainerRef: ViewContainerRef) {
        this.workspace = (viewContainerRef as any)._view.component;
    }
    
}

由于某种原因（可能是在类路径上），我在尝试获取viewContainerRef.\u视图时遇到了错误

TypeError: Cannot read property 'component' of undefined
    at new SomeDirectiveDirective (someDirective.directive.ts:18)
    at NodeInjectorFactory.SomeDirectiveDirective_Factory [as factory] (ɵfac.js? [sm]:1)
    at getNodeInjectable (core.js:5993)
    at instantiateAllDirectives (core.js:12997)
    at createDirectivesInstances (core.js:12209)
    at ɵɵelementStart (core.js:21302)
    at WorkspaceComponent_Template (template.html:1)
    at executeTemplate (core.js:12169)

调试它时，我看到viewContainerRef不包含_view，而是包含_hostView

值_view和_hostView来自哪里？ 它和常春藤编译器有关？如果是这样，这意味着我的“angularCompilerOptions”被忽略了，对吗

ng version

PS-这些信息足够吗？ 编辑-添加了编译器选项
