3) Open the packages.json of your main project and change the following versions of dependencies:,

Is centripetal acceleration almost perpendicular to velocity or it is exactly perpendicular to velocity?

,Once removed the circular dependency, everything worked fine.,I had the same problem with my [email protected] project after updating the CLI globally to version 8 and solve it by upgrading angular in my project to the latest version by running this command in my project directory:

Hi:
I am getting error:
An unhandled exception occurred: Object prototype may only be an Object or null: undefined
when trying to build project in CI.
I found out the following dependencies while testing to build project:,https://stackoverflow.com/questions/57421582/typeerror-object-prototype-may-only-be-an-object-or-null-undefined-angular-8,Search or submit bugs against the npm CLI or any of our other maintained OSS projects,We have empty node_modules and no package-lock.json file.
So I do npm install (it will create package-lock) then ng build —prod

Getting the error «Object prototype may only be an Object or null: undefined» when running «ionic serve»,Steps to reproduce:
Started getting this cryptic error message out of nowhere when I upgraded the Ionic CLI, ionic-app-scripts, and ionic-angular to the latest versions.,In my case there was a circular reference problem too. However, it was the export order on an index.ts file that was causing the problem.,Open the packages.json of your main project and change the following versions of dependencies:
«@angular/*»
«@ionic-native/*»
«rxjs»
Also, replace the «scripts» part.

Answer by Hugh McPherson

As you saw, changing Customer.ts to import from ./Entity directly instead of ./index breaks the cycle, and everything works as expected. Another solution would be to reverse the order of imports in index.ts.

As I suspected, your original program has circular imports. Run.ts imports index.ts, which imports Customer.ts, which imports index.ts again. Since index.ts is already in the process of loading and itself depends on Customer.ts, the import { Entity } from "./index"; just binds the Entity of index.ts (which is not set yet) to the Entity of Customer.ts, and execution proceeds even though index.ts isn’t finished loading. Then Entity is undefined at the time you try to extend it. You might argue that a circular import should be an error or that JavaScript engines should use some other algorithm that correctly handles your scenario; I’m not qualified to comment on why the current design was chosen. (Others feel free to add information about this.)

#javascript #node.js #es6-modules #vite #filestack

Вопрос:

Я использую filestack-js в проекте Rails, который поставляется в комплекте с Vite. Все работает так, как ожидалось, пока я не включу модуль ESM для filestack-js библиотеки, в данном случае в контроллер StimulusJS:

 import { Controller } from "stimulus";

import * as filestack from "filestack-js";

export default class extends Controller {
  // some irrelevant implementation code that calls filestack.init(...)
}
 

Загрузка вышеуказанного файла контроллера в браузере вызывает ошибку:

 tslib.es6.js:25 Uncaught TypeError: Object prototype may only be an Object or null: undefined
    at setPrototypeOf (<anonymous>)
    at __extends (tslib.es6.js:25)
    at http.ts:43
    at node_modules/filestack-js/build/module/lib/request/adapters/http.js (http.ts:64)
    at __init (chunk-IHTDASF6.js?v=1616a449:14)
    at request_adapter.node.ts:17
 

Это ошибка, вызванная браузером при работе в среде разработки, при использовании Vite для создания и обслуживания модулей ES непосредственно в браузере. Он обрабатывает компиляцию машинописного текста. Удаление import * as filestack бита устраняет ошибку (но, очевидно, нарушает функциональность класса).

Мои поиски в Google, похоже, предполагают, что это может быть проблемой циклической зависимости. Трассировка стека браузера указывает на файл в filestack-js библиотеке:

 // src/lib/request/adapters/http.ts

import * as url from 'url';
import * as zlib from 'zlib';
import Debug from 'debug';

import { AdapterInterface } from './interface';
import { getVersion } from '../../utils';
import * as Stream from 'stream'; // <---------- Stream imported here
import { FsRequestOptions, FsResponse } from '../types';
import * as utils from '../utils';
import { prepareData, parseResponse, combineURL, set as setHeader, normalizeHeaders } from './../helpers';
import { FsRequestErrorCode, FsRequestError } from '../error';
import { FsHttpMethod } from './../types';

const HTTPS_REGEXP = /https:?/;
const HTTP_CHUNK_SIZE = 16 * 1024;
const MAX_REDIRECTS = 10;
const CANCEL_CLEAR = `FsCleanMemory`;
const debug = Debug('fs:request:http');

class HttpWritableStream extends Stream.Writable {
  // omitted class definition
}
 

Где Stream.Writable на самом деле не определено из-за проблемы циклической зависимости. Я понятия не имею, как это могло произойти или, похоже, повлияло только на меня.

Это не проблема, о которой сообщалось в отслеживателе проблем filestack-js.

Отладка в браузере и локальное клонирование/связывание репозитория подтвердили , что Stream.Writable это возвращается undefined , но я недостаточно знаю о JS, чтобы понять, почему. Предположительно, это обычно происходит из-за циклической зависимости, но я не уверен, как модуль nodejs Stream будет иметь циклические зависимости от случайной библиотеки, например filestack-js . Я также достаточно неопытен в мире JS, чтобы точно понять, что значит использовать библиотеку NodeJS, как Stream в модуле браузера, — filestack-js в ней есть как браузерные модули, так и модули CommonJS/NodeJS, поэтому я не уверен, как/связаны ли они или взаимодействуют.

Вот как Stream выглядит объект при входе в консоль браузера. Очевидно, что что-то было импортировано, но Writable не является свойством того, что было импортировано:

консоль браузера

FWIW это происходит в Chrome и Firefox, последних версиях каждого из них.

Я также попытался использовать dpdm для анализа проекта filestack-js на наличие циклических зависимостей. Он нашел некоторые, но не похоже, что они вызывают ошибки, и, похоже, явно исключаются библиотеки узлов и другие библиотеки зависимостей.

Комментарии:

1. Хорошо, я вижу, что это может быть связано с тем фактом, что Vite использует накопительный пакет под капотом, и этот накопительный пакет может не справляться с определенными циклическими зависимостями, существующими в библиотеках NodeJS? это репозиторий существует, и кажется, что он может быть разработан для решения такого рода проблем, но, похоже, он не работает для меня.

2. Действительно ли этот стимул и ваш собственный класс необходимы для того, чтобы вызвать проблему, или это уже происходит, если все, что вы делаете, — это импортируете filestack-js библиотеку?

3. @Bergi Я могу подтвердить, что это не имеет отношения к делу. Просто так получилось, что я пользуюсь библиотекой именно там. Извини, что я не ясно выразился.

4. В этом случае я бы определенно сообщил об этом как об ошибке в их системе отслеживания проблем. Тем более, что документация утверждает, что работает с накопительным пакетом из коробки. Однако вам следует поделиться своей конфигурацией свертки

5. Ого, я пропустил эту ссылку на свертку. До сих пор я не решался опубликовать проблему, потому что у меня нет простого решения, но, думаю, я мог бы придумать более простое. Спасибо.

Ответ №1:

Хорошо, я думаю, что решил свою проблему, но я не эксперт, поэтому я попытаюсь объяснить, в чем была проблема. Не стесняйтесь вступать в разговор с разъяснениями, если вам лучше известно.

Это было вызвано filestack-js интенсивным использованием библиотек nodejs. Исторически сложилось так, что Webpack v4 заполнил множество распространенных библиотек NodeJS для использования в браузере, полностью прозрачных для большинства разработчиков. Это прекрасно работало, но было полным волшебством.

Накопительный пакет и, кстати, Webpack v5 не выполняют этого заполнения, поэтому любые библиотеки NodeJS, используемые библиотеками «ESM» из NPM, которые напрямую не совместимы с современными браузерами, просто сломаются. Чтобы заполнить это вручную, мне пришлось поручить Vite amp; Rollup присвоить псевдоним имени модуля nodejs stream чему-то, что напрямую совместимо с браузерами, и установить его. Чтобы сделать это, я:

 yarn add --dev stream-browserify
 

И добавил следующее к моему vite.config.js :

 // ...
resolve: {
  alias: {
    stream: "stream-browserify",
  },
},
// ...
 

Должен быть очень похожий (но другой) способ сообщить свертке, чтобы сделать это, потому что здесь я делаю это через конфигурацию Vite.
