第一步: 直接打开package.json

第二步: 直接替换scripts的内容为下面的内容

  "scripts": {
    "dev": "SET NODE_OPTIONS=--openssl-legacy-provider && vue-cli-service serve",
    "build:prod": "SET NODE_OPTIONS=--openssl-legacy-provider && vue-cli-service build",
    "build:stage": "vue-cli-service build --mode staging",
    "electron:serve": "vue-cli-service electron:serve",
    "electron:build": "vue-cli-service electron:build",
    "electron:build:win32": "vue-cli-service electron:build --win --ia32",
    "preview": "node build/index.js --preview",
    "lint": "eslint --ext .js,.vue src"
  },

大功告成, 然后 npm run dev自己试试吧.
