摆脱相对路径反应（删除“../..”）

Question

我已经下载了一个包含以下 package.json 的 React 项目：

{
  "private": true,
  "main": "src/index.js",
  "dependencies": {
    "@material-ui/core": "4.10.0",
    "@material-ui/icons": "4.9.1",
    "classnames": "2.2.6",
    "history": "4.10.1",
    "moment": "2.26.0",
    "node-sass": "4.14.1",
    "nouislider": "14.5.0",
    "prop-types": "15.7.2",
    "react": "16.13.1",
    "react-datetime": "2.16.3",
    "react-dom": "16.13.1",
    "react-router-dom": "5.2.0",
    "react-scripts": "3.4.1",
    "react-slick": "0.26.1",
    "react-swipeable-views": "0.13.9"
  },
  "devDependencies": {
    "@babel/cli": "7.10.1",
    "@babel/plugin-proposal-class-properties": "7.10.1",
    "@babel/preset-env": "7.10.1",
    "@babel/preset-react": "7.10.1",
    "eslint-config-prettier": "6.11.0",
    "eslint-plugin-prettier": "3.1.3",
    "eslint-plugin-react": "7.20.0",
    "gulp": "4.0.2",
    "gulp-append-prepend": "1.0.8",
    "prettier": "2.0.5"
  },
  "optionalDependencies": {
    "typescript": "3.9.3"
  },
  "scripts": {
    "start": "NODE_PATH=src/ react-scripts start",
    "build": "react-scripts build && gulp licenses",
    "test": "react-scripts test --env=jsdom",
    "eject": "react-scripts eject",
    "lint:check": "eslint . --ext=js,jsx;  exit 0",
    "lint:fix": "eslint . --ext=js,jsx --fix;  exit 0",
    "install:clean": "rm -rf node_modules/ && rm -rf package-lock.json && npm install && npm start",
    "build-package-css": "node-sass src/assets/scss/material-kit-react.scss dist/material-kit-react.css",
    "build-package": "npm run build-package-css && babel src --out-dir dist",
    "compile-sass": "node-sass src/assets/scss/material-kit-react.scss src/assets/css/material-kit-react.css",
    "minify-sass": "node-sass src/assets/scss/material-kit-react.scss src/assets/css/material-kit-react.min.css --output-style compressed",
    "map-sass": "node-sass src/assets/scss/material-kit-react.scss src/assets/css/material-kit-react.css --source-map true"
  }
  
}

我不知道开发人员如何摆脱代码中的相对路径。例如，他导入如下模块：import Header from "components/Header/Header.js"; 尽管如果我尝试相同，我应该这样做：import header from "../../../src/components/Header/header.js"。

原始github链接： https://github.com/creativetimofficial/material-kit-react/

我已经下载并安装了这个，它工作正常。但是当我尝试复制一些代码时，它不起作用。

Answer 1

使用jsconfig.json设置绝对路径而不是相对路径，如文档中所述

在他提供的项目中使用

{
  "compilerOptions": {
    "baseUrl": "src",
    "paths": {
      "*": ["src/*"]
    }
  }
}

这样他就可以使用绝对路径访问项目的所有文件夹和子文件夹中的所有文件，例如

import file from "component/file/file.js"
