启动Vue出现npm ERR! code ENOENT和npm ERR! Missing script: "serve"

npm ERR! code ENOENT
npm ERR! syscall open
npm ERR! path D:\java\springbootAndVue\前端/package.json
npm ERR! errno -4058
npm ERR! enoent ENOENT: no such file or directory, open 'D:\java\springbootAndVue\前端\package.json'
npm ERR! enoent This is related to npm not being able to find a file.
npm ERR! enoent

因为

npm ERR! path D:\java\springbootAndVue\前端/package.json

原先的是

 

 需要把package-lock.json的-lock去掉

成package-lock.json就好了

npm ERR! Missing script: "serve"
npm ERR!
npm ERR! To see a list of scripts, run:
npm ERR!   npm run

将package-lock.json中的sciptsd修改为

"scripts": {
    "serve": "vue-cli-service serve",
    "build": "vue-cli-service build",
    "lint": "vue-cli-service lint",
    "dev": "vue-cli-service serve",
    "build:prod": "vue-cli-service build",
    "build:stage": "vue-cli-service build --mode staging",
    "preview": "node build/index.js --preview",
    "test:unit": "jest --clearCache && vue-cli-service test:unit",
    "test:ci": "npm run lint && npm run test:unit",
    "svgo": "svgo -f src/icons/svg --config=src/icons/svgo.yml",
    "new": "plop"
  }

就好了，我原先没有sciptsd的，后面我自己加上

{
  "name": "前端",
  "lockfileVersion": 2,
  "requires": true,
  "packages": {},
"scripts": {
    "serve": "vue-cli-service serve",
    "build": "vue-cli-service build",
    "lint": "vue-cli-service lint",
    "dev": "vue-cli-service serve",
    "build:prod": "vue-cli-service build",
    "build:stage": "vue-cli-service build --mode staging",
    "preview": "node build/index.js --preview",
    "test:unit": "jest --clearCache && vue-cli-service test:unit",
    "test:ci": "npm run lint && npm run test:unit",
    "svgo": "svgo -f src/icons/svg --config=src/icons/svgo.yml",
    "new": "plop"
  }
}
