nodejs debug官方方法（包括本地调试和远程调试） 转了一圈发现看超链接的文章就够了
使用webstorm调试
-
本地调试：run->debug 配置启动文件，然后打断点即可
-
远程调试：在Webstorm项目窗口中，打开Run/Debug Configurations窗口，点击 加号（+）选择“Attach to Node.js/Chrome”，启动配制。
node-inspector
最近在用nodemailer写邮件的相关功能，网上搜了下nodejs的调试工具，但是使用
npm install -g node-inspector
命令安装失败，报错如下：
node-pre-gyp ERR! Tried to download(undefined): https://node-inspector.s3.amazonaws.com/debug/v1.0.1/node-v64-darwin-x64.tar.gz
node-pre-gyp ERR! Pre-built binaries not found for v8-debug@1.0.1 and node@10.6.0 (node-v64 ABI, unknown) (falling back to source compile with node-gyp)
Node V8 的调试 API 发生了很大变化，Node inspector 基本废了
解释： Node8 brings a big break change in the debug api which is too difficult to implement in Node Inspector. Besides it provides a built-in DevTools-based debugger which mostly deprecates Node Inspector. So basically you can just use the built-in debugger tools. https://nodejs.org/en/docs/inspector/
新的内置方法调试nodejs
安装 node-inspect，注意和 node-inspector 的细微区别，执行命令 npm install -g node-inspect. 然后输入 node –inspect server.js启动调试
打开 Chrome 浏览器，输入 chrome://inspect
