无法理解反应依赖中的问题

Not able to understand the issue in react dependency

我必须对多种语言使用 React 翻译。我在安装的时候

"i18next": "^21.6.3",
"react-i18next": "^11.15.1",

它开始抛出错误。

这是我的i18.js

import i18n from 'i18next';
import { initReactI18next } from 'react-i18next';

import translationEN from '../public/locales/en/translation.json';

// the translations
const resources = {
  en: {
    translation: translationEN,
  },
};

i18n
  .use(initReactI18next) // passes i18n down to react-i18next
  .init({
    resources,
    lng: 'en',

    keySeparator: false, // we do not use keys in form messages.welcome

    interpolation: {
      escapeValue: false, // react already safes from xss
    },
  });

export default i18n;

下面是我的package.json。我无法理解是依赖性问题还是 i18 file

你能帮我解决同样的问题吗? 你能指导我我的主要依赖项如 reactreact-domi18next 和其他一些是否兼容吗?即使您不检查其他人,但请检查主要依赖项。如果你只能帮我调试 star-rating.jsx 它会帮助我调试其他人。我什至没有对这个文件做任何更改,它仍然给出错误。

我认为问题出在您为 StarRating.

声明道具类型的地方
StarRating.propTypes = {
  name: React.PropTypes.string.isRequired,
  caption: React.PropTypes.string,
  ratingAmount: React.PropTypes.number.isRequired,
  rating: React.PropTypes.number,
  onRatingClick: React.PropTypes.func,
  disabled: React.PropTypes.bool,
  editing: React.PropTypes.bool,
  size: React.PropTypes.string,
};

PropTypes 很久以前就从 React 移走了,如果我没记错的话,回到 React v15。

Typechecking with PropTypes

Note:

React.PropTypes has moved into a different package since React v15.5. Please use the prop-types library instead.

We provide a codemod script to automate the conversion.

您已经在使用 PropTypes 软件包:

"prop-types": "^15.5.10",

所以我认为这里的解决方案是导入 PropTypes 并简单地删除 React. 前缀:

import PropTypes from 'prop-types';

...

StarRating.propTypes = {
  name: PropTypes.string.isRequired,
  caption: PropTypes.string,
  ratingAmount: PropTypes.number.isRequired,
  rating: PropTypes.number,
  onRatingClick: PropTypes.func,
  disabled: PropTypes.bool,
  editing: PropTypes.bool,
  size: PropTypes.string,
};

根据 React 当前版本,定义 propTypes 似乎是错误的,不需要从 React 中提取 propTypes,因为它带有一个单独的包。

因此,声明道具的正确语法是

  StarRating.propTypes = {
  name: PropTypes.string.isRequired,
  caption: PropTypes.string,
  ratingAmount: PropTypes.number.isRequired,
  rating: PropTypes.number,
  onRatingClick: PropTypes.func,
  disabled: PropTypes.bool,
  editing: PropTypes.bool,
  size: PropTypes.string,
  };
