Question

D3v5函数在开发模式下工作正常，但在生产模式下抛出运行时错误

错误TypeError ：（无效0）不是函数

键入脚本代码

import { Component } from '@angular/core';
import {timeFormat} from 'd3-time-format';
...
export class AppComponent {

  constructor(){
    var formatTime = timeFormat("%B %d, %Y");
   console.log('Time parser :: ', formatTime(new Date))
  }
}

Package.json

  "dependencies": {
    "@angular/animations": "~8.1.1",
    "@angular/common": "~8.1.1",
    "@angular/compiler": "~8.1.1",
    "@angular/core": "~8.1.1",
    "@angular/forms": "~8.1.1",
    "@angular/platform-browser": "~8.1.1",
    "@angular/platform-browser-dynamic": "~8.1.1",
    "@angular/router": "~8.1.1",
    "@types/d3": "^5.7.2",
    "d3": "^5.13.1",
    "rxjs": "~6.4.0",
    "tslib": "^1.9.0",
    "zone.js": "~0.9.1"
  },

tsconfig.json-还尝试根据Error in d3.js after upgrading to Angular 8

更新目标

{
  "compileOnSave": false,
  "compilerOptions": {
    "baseUrl": "./",
    "outDir": "./dist/out-tsc",
    "sourceMap": true,
    "declaration": false,
    "downlevelIteration": true,
    "experimentalDecorators": true,
    "module": "esnext",
    "moduleResolution": "node",
    "importHelpers": true,
    **"target": "es5",**
    "typeRoots": [
      "node_modules/@types"
    ],
    "lib": ..
  },
  "angularCompilerOptions": ..
}

任何建议或线索将不胜感激。

谢谢

对于遇到类似问题的任何人，我都可以通过将d3撞到以下版本上来使其正常工作

 "dependencies": {
    "@angular/animations": "~8.2.14",
    "@angular/common": "~8.2.14",
    "@angular/compiler": "~8.2.14",
    "@angular/core": "~8.2.14",
    "@angular/forms": "~8.2.14",
    "@angular/platform-browser": "~8.2.14",
    "@angular/platform-browser-dynamic": "~8.2.14",
    "@angular/router": "~8.2.14",
    "@types/d3": "^5.7.2",
    "d3": "^5.14.0",
    "rxjs": "~6.4.0",
    "tslib": "^1.10.0",
    "zone.js": "~0.9.1"
  },

从更新@ angular-devkit / build-angular版本后

“ @ angular-devkit / build-angular”：“〜0.801.2”

到

“ @ angular-devkit / build-angular”：“ ^ 0.803.17”

为我工作。
