    11月29日 18:52Port 9244 is already in use. Use '--port' to specify a different port.
    npm ERR! code ELIFECYCLE
    npm ERR! gpsoft@0.0.0 start: `ng serve --host 0.0.0.0 --port 9244 --proxy-config loca.conf.json --base-href /gpmes/ -o`
    npm ERR! Exit status 1
    npm ERR!
    npm ERR! Failed at the gpsoft@0.0.0 start script.
    npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

    npm ERR! A complete log of this run can be found in:
    npm ERR!     C:\Users\17420\AppData\Roaming\npm-cache\_logs\2022-11-29T10_39_02_126Z-debug.log

    解决办法

  • 用Windows+R键，输入cmd进入DOS窗口，输入命令：netstat -ano|findstr 9244 找到该端口号对应的PID号
  • 用命令taskkill /pid 11464 /F 强制杀掉进程 （11464）为PID号，显示成功过后，再次运行npm start成功运行
