报错npm WARN Local package.json exists, but node_modules missing, did you mean to install?的解决办法

客户开发项目采用Vue开发，执行npm run dev命令时出现以下错误:

> mix

‘mix’ 不是内部或外部命令，也不是可运行的程序

或批处理文件。

npm ERR! code ELIFECYCLE

npm ERR! errno 1

npm ERR! @ development: `mix`

npm ERR! Exit status 1

npm ERR!

npm ERR! Failed at the @ development script.

npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

npm WARN Local package.json exists, but node_modules missing, did you mean to install?

npm ERR! A complete log of this run can be found in:

npm ERR! C:\Users\Administrator\AppData\Roaming\npm-cache\_logs\2022-07-07T03_20_04_511Z-debug.log

我们需要把依赖关系包更新一下才行

解决方法：npm install

运行完成之后，再次执行npm run dev

终于编译成功！
