yarn add react react-dom

   "name": "parcel-example-react-helloworld",
   "version": "1.0.0",
   "description": "",
   "main": "index.js",
   "scripts": {
     "test": "echo \"Error: no test specified\" && exit 1"
   },
   "keywords": [],
   "author": "",
-  "license": "ISC"
+  "license": "ISC",
+  "dependencies": {
+    "react": "^16.2.0",
+    "react-dom": "^16.2.0"
+  }
 }

3. 添加 Babel

新建 .babelrc 文件

touch .babelrc

输入内容：

{
  "presets": ["react"]
}

添加 babel-preset-react：

yarn：

yarn add babel-preset-react -D

npm:

npm install babel-preset-react --D

此时 package.json 文件内容：

 {
   "name": "parcel-example-react-helloworld",
   "version": "1.0.0",
   "description": "",
   "main": "index.js",
   "scripts": {
     "test": "echo \"Error: no test specified\" && exit 1"
   },
   "keywords": [],
   "author": "",
   "license": "ISC",
   "dependencies": {
     "react": "^16.2.0",
     "react-dom": "^16.2.0"
-   }
