экспорт 'utils' (импортированный как 'utils') не был найден в 'ethers'

Question

Я пытаюсь создать веб-приложение, которое может взаимодействовать с блокчейном, я использую брауни в качестве основы прочности и реагирую. Я установил useDapp для подключения к своему кошельку. но при первом простом использовании я получил эту ошибку:

        Hello!

}

export default App;

пожалуйста, какие-либо предложения, чтобы исправить эту ошибку?

Answer 1

наконец, я понял проблему. Я удалил пакет «эфиры», а затем вручную установил версию 5.6.9 с помощью следующих команд:

      $ yarn remove ethers
$ yarn add ethers@5.6.9

это сработало хорошо для меня

Answer 2

ethers.js перенесен с версии 5 на версию 6. Многие вещи из версии 5 больше не поддерживаются в версии 6, включая утилиты. https://docs.ethers.org/v6/migrating/

Ваша проблема имеет два решения:

1. Понизьте версию ethers.js до «5.7.2». Если вы используете npm, выполните эту команду

      npm i ethers@5.7.2

2. Если вы решите использовать v6, используйте следующее:

      ethers.formatEthers(value)

Answer 3

Вот и все... последнее решение для просмотра документации по миграции для ethers v6 работает. Понижение версии v5 вызвало у меня другие проблемы.

Итак, это сработало для меня:

• Исправление следования рекомендациям по переходу на версию 6 на docs.ethers.org https://docs.ethers.org/v6/migrating/#migrate-utils.

• используйте последнюю версию "эфиров": "^6.6.4",

• изменить расширение файла .js -> .mjs(Файл с расширением .mjs — это файл исходного кода JavaScript, который используется в качестве модуля ECMA (модуль ECMAScript) в приложениях Node.js.)https://docs.fileformat.com /веб/мджс/

• менять скрипты

// импортирует старые:

      import { ethers } from "ethers";
import { keccak256, toUtf8Bytes } from "ethers/lib/utils.js";

новый:

      import { ethers, keccak256, toUtf8Bytes  } from "ethers";

// getProvider старый:

      function gp() {return new ethers.providers.JsonRpcProvider(endpoint);
}

новый:

      function gp() {return new ethers.JsonRpcProvider(endpoint);}

Answer 4

Вероятно, вы используете эфиры v6.

Пытаться:

      ethers.formatEther(value);

Документация здесь:ethers v6 #formatEther
