vue.esm.js?a026:591 [Vue warn]: $attrs is readonly.
vue.esm.js?a026:591 [Vue warn]: $listeners is readonly.
---> <ElInput> at packages/input/src/input.vue
       <Root>

就是报这样的错误

原因:vue和elementUI的版本不匹配

解决办法:升级vue和elementUI的版本就好了

查询端口命令:

netstat -ano|findstr 48000

杀死进程命令:

taskKill /T /F /PID 17264

bat 文件中%0、%1等是表示什么

x:目录下有test.bat, 内容如下:

@echo offstart %1start %3

直接cmd窗口执行如下命令:

 x>.\test.bat -Dcom.bokesoft.sts.appcode=1111 222 333
 
%1: -Dcom.bokesoft.sts.appcode=1111
%2: 222
%3: 333

执行结果输出如下:

offstart -Dcom/bokesoft/sts/appcode:1111start 333

因命令行里只有%1 & %3,没有%2故而没有输出222 1663237028396
