如何为无服务器项目设置版本？

我已通过1.38.0命令将无服务器降级为npm install -g [email protected]版本。使用以下npm install

{
  "name": "serverless-defaults",
  "version": "1.6.0",
  "description": "description",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "repository": {
    "type": "git",
    "url": "git+/???"
  },
  "bugs": {
    "url": "/???"
  },
  "homepage": "/???#readme",
  "license": "MIT",
  "private": true,
  "devDependencies": {
    "serverless-cf-vars": "^0.3.2",
    "serverless-domain-manager": "3.2.7",
    "serverless-pseudo-parameters": "^2.4.0",
    "serverless-step-functions": "^2.6.0"
  }
}

并得到：

cmd.exe /c "npm install"
npm WARN deprecated [email protected]: Please note that v5.0.1+ of superagent removes User-Agent header by default, therefore you may need to add it yourself (e.g. GitHub blocks requests without a User-Agent header).  This notice will go away with v5.0.2+ once it is released.

为什么[email protected]为什么出现在日志中？？？ npm的最新无服务器版本在哪里？？？在哪里指定我需要的无服务器版本？
