【问题描述】：

我已通过npm install -g serverless@1.38.0 命令将无服务器降级为1.38.0 版本。在具有以下 package.json 的文件夹上调用 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+https://github.com/???"
  },
  "bugs": {
    "url": "https://github.com/???"
  },
  "homepage": "https://github.com/???#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"
  }
}

得到：

cmd.exe /c "npm install"
npm WARN deprecated superagent@3.8.3: 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serverless@1.53.0 会出现在日志中？？？ npm 哪里有最后一个无服务器版本？？？在哪里指定我需要的无服务器版本？

【问题讨论】：

标签： javascript node.js json npm serverless-framework

【解决方案1】：

serverless-step-functions depends directly 在无服务器框架上。我的猜测是它正在解析为最新的兼容版本。

尝试在您的 package.json 中添加一个新条目：

"dependencies": {
  "serverless": "1.38.0"
}

这应该确保serverless-step-functions 不会安装更新版本的框架。
