Eclipse Plugin Debug NPM package node-inspector Debug

• NPM install-g Node-inspector (which requires vs compilation, if vs2012 is installed, set the compiled vs version, otherwise it might compile.) NPM config set msvs_version--global)
• Start App.js:node--debug-brk=5858 App.js, where the port number can be modified
• Start Node-inspector:node-inspector--web-port=8000--web-host=192.168.39.129--debug-port=5858 &, where 5858 is consistent with the previous article, Web-port is the Web port that is started, Web-host is the IP address of the Web that is started. Remote debugging can be implemented.
• Open Google Chrome, enter the address http://192.168.39.129:8000/debug?port=5858 to debug
