比如我执行了 npm install --save-dev del 后，package.json里自动在 devDependencies 添加了一条依赖，但是我不希望他是以 ^ 开头，我希望他默认是以 ~ 开头。这个需要什么特殊设置吗

 {
  "name": "xxx",
  "version": "0.1.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "xxxx",
  "license": "MIT",
  "devDependencies": {
    "del": "^1.1.1"
  }
}

希望执行完安装命令后是这样的结果

 {
  "name": "xxx",
  "version": "0.1.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "xxxx",
  "license": "MIT",
  "devDependencies": {
    "del": "~1.1.1"
  }
}
