npm ERR! enoent This is related to npm not being able to find a file.

报错信息：

admin:$ npm run dev
npm ERR! code ENOENT
npm ERR! syscall open
npm ERR! path /Users/admin/package.json
npm ERR! errno -2
npm ERR! enoent ENOENT: no such file or directory, open '/Users/admin/package.json'
npm ERR! enoent This is related to npm not being able to find a file.
npm ERR! enoent 

解决办法：

有几个原因，遇到过删除项目中的node_modules，然后重新安装nom install也解决了。

今天这个方法不凑效，仔细看报错信息，可能是启动的项目地址路径不对，重新进入项目，再输入命令npm run dev，就能正常启动了。
