nodemon使用报错restarting due to changes...建议改用supervisor

困扰了我两天了的一个问题,下面是我的使用过的方法

1.重启（没啥用）

2.重装nodemon,再删掉之后全局安装和本地安装

3.重装node

4.添加系统环境变量详见(https://blog.csdn.net/Vrainy/article/details/107268357)

这个没解决我的问题，但是说不定能解决你的问题

5.安装supervisor

说回报错原因，其实到现在我都不知道，可能是nrn或者是Gulp的原因。但是只是可能，毕竟我也做了一点别的事情。

总之，难以解决，又不想浪费太多时间，毕竟这个错误有点不知所措…

安装supervisor过程和nodemon差不太多

1.npm install -g supervisor

2.supervisor app.js

这是nodemon的报错

这是supervisor的执行结果，亲测好用，建议新手遇到nodemon的上述错误不要过分纠结，先使用这个进行替代，毕竟组建的更迭或者是更深的问题新手总之有些乏力，反而会影响继续的学习热情，所以建议先使用supervisor。
