VsCode 执行 npm run dev 失败

今天在执行 npm run dev 时 ,启动不成功 .

异常代码

Note that the development build is not optimized. To create a production build, run npm run build. events.js:292 throw er; // Unhandled ‘error’ event ^ Error: spawn cmd ENOENT at Process.ChildProcess._handle.onexit (internal/child_process.js:269:19) at onErrorNT (internal/child_process.js:465:16) at processTicksAndRejections (internal/process/task_queues.js:80:21) Emitted ‘error’ event on ChildProcess instance at: at Process.ChildProcess._handle.onexit (internal/child_process.js:275:12) at onErrorNT (internal/child_process.js:465:16) at processTicksAndRejections (internal/process/task_queues.js:80:21) { errno: -4058, code: ‘ENOENT’, syscall: ‘spawn cmd’, path: ‘cmd’, spawnargs: [ ‘/c’, ‘start’, ‘“”’, ‘/b’, ‘localhost:9528/’ ] } npm ERR! code ELIFECYCLE npm ERR! errno 1 npm ERR! flash-vue-admin@4.1.0 dev: vue-cli-service serve --open npm ERR!

解决方法 :

方法一 :

在环境变量Path中添加 C:\\Windows\\System32

1.右键此电脑-- 属性 – 高级系统设置 – 高级 – 环境变量 – 系统变量,找到Path,双击新建路径。

2.重启项目就OK了

如果不是以上问题 ,可以看一下,下面的文章
