从 Github 启动一个克隆的 create-react-app

Question

我已经尝试了一段时间运行一个相对简单的 React 应用程序。一位同事使用 create-react-app 启动了该项目，但由于某种原因我无法启动该应用程序。

错误代码如下：

Error [ERR_INVALID_PACKAGE_TARGET]: Invalid "exports" main target "index.js" defined in the package config /home/francisco/Desktop/University/Data%20visualization/Bialystok-DataVisualization-Project/node_modules/is-promise/package.json

NPM 然后继续显示以下错误：

npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! data-visualization-project@0.1.0 start: `react-scripts start`
npm ERR! Exit status 1

我已经运行以下命令：npm install 和 npm start。我也试过删除 package-lock.json 和 node_modules 并重新运行 npm install，但没有解决方案。

我目前运行正在使用 npm 版本 6.14.4 和节点 13.11.0

编辑：添加文件 index.js

import React from 'react';
import ReactDOM from 'react-dom';
import './index.css';
import App from './App';
import * as serviceWorker from './serviceWorker';
import 'bootstrap/dist/css/bootstrap.css';
import "handsontable/dist/handsontable.full.css";

ReactDOM.render(
  <React.StrictMode>
    <App />
  </React.StrictMode>,
  document.getElementById('root')
);

// If you want your app to work offline and load faster, you can change
// unregister() to register() below. Note this comes with some pitfalls.
// Learn more about service workers:
serviceWorker.unregister();

package.json

{
  "name": "data-visualization-project",
  "version": "0.1.0",
  "private": true,
  "dependencies": {
    "@handsontable/react": "^3.1.3",

  },
  "scripts": {
    "start": "react-scripts start",
    "build": "react-scripts build",
    "test": "react-scripts test",
    "eject": "react-scripts eject"
  },
  "eslintConfig": {
    "extends": "react-app"
  },
  "browserslist": {
    "production": [
      ">0.2%",
      "not dead",
      "not op_mini all"
    ],
    "development": [
      "last 1 chrome version",
      "last 1 firefox version",
      "last 1 safari version"
    ]
  }
}

感谢您的帮助！

Answer 1

npm/node 和 create-react-app 目前存在一些问题。我设法通过安装节点版本 12.12.0 解决了类似的问题。也许这可以解决您的问题。

Answer 2

先尝试清理缓存

npm cache clean --force

然后做你已经做过的事情:

删除node_modules并打包-lock.json
npm i
npm start

Answer 3

重新安装 create-react-app：

npm install -g --force create-react-app

它修复了它们。

如果没有，请确保你有 is-promise@2.2.2 old older，通过命令：

npm list is-promise

从 Github 启动一个克隆的 create-react-app

Start a cloned create-react-app from Github

node.js

npm

reactjs

create-react-app
