设置Node.js和NPM
升级Node(n不支持Windows操作系统)：
node -v #查看Node版本
npm cache clean -f #清除Node的缓存
npm install -g n #安装n工具，该工具是专门管理Node版本的工具
n stable #安装最新稳定的Node版本
升级NPM：
npm -v #查看NPM版本
npm install npm@latest -g #安装最新稳定的NPM版本
我在两台机器上安装了Node 12.16.2 TLS，其中一台机器上npm死活有问题，从Node 10.16版本开始总是报错verbose stack TypeError: Cannot read property 'resolve' of undefined。
最后在那台机器上重新安装了Node 10.15.3,才避免了问题。
安装Chrome插件React Developer Tools
从Chrome Extensions上搜索React Developer Tools进行安装。
安装后，在Chrome开发者工具中可以看到React的Components和Profiler两个Tab并使用。
安装脚手架create-react-app
npm install -g create-react-app
使用create-react-app创建React项目
C:\devpg>create-react-app hello-react

Created git commit.
Success! Created hello-react at C:\devpg\hello-react
Inside that directory, you can run several commands:
npm start
Starts the development server.
npm run build
Bundles the app into static files for production.
npm test
Starts the test runner.
npm run eject
Removes this tool and copies build dependencies, configuration files
and scripts into the app directory. If you do this, you can’t go back!
We suggest that you begin by typing:
cd hello-react
npm start
Happy hacking!
C:\devpg>
要是觉得npm下载挺慢的，可以提前改用国内taobao的npm源：npm config set registry https://registry.npm.taobao.org。
