在现有 package.json 中安装新的依赖项
Installing a new dependency in existing package.json
前言： 我是 JavaScript 的新手，我知道这是一个基本问题，但我看到有几种不同的方法可以将依赖项添加到现有 JavaScript 个项目。我检查了几个不同点的文档以确保我不会搞砸它，尽管安装了文件，但我的终端中有一堆东西表明我遇到了问题。
这是我所做的：
我有一个最初安装了 chai 的项目。进一步，我发现我需要测试 JSON 个文件，我发现 Chai 有一个名为 chai-json-schema 的包，所以我仔细检查了安装说明并安装了它。
要安装，我从项目的根目录输入：
// --save is supposed to put it in the package.json file
npm install --save chai-json-schema
已记录：

我认为 npm 需要与我安装的版本不同的版本。我急于避免将其变成一团糟的递归，所以我在这里发帖。
清理安装的最佳方法是什么？

更新：
我试图使用 chai-json-schema JSON 包来测试 return 值是否为 JSON。我发现股票 chai 有一种方法可以测试 return 的值是 JSON，这解释了为什么 chai-son-schema 已经一年多没有更新了。:
return expect(value).to.be.json; // tests if it's a json response
该错误告诉您安装的 chai 软件包版本不满足 chai-json-schema 要求的版本。
如果您查看 chai-json-schema 包的 package.json，您会发现它需要以下 chai 版本：
"peerDependencies": {
"chai": ">= 1.6.1 < 3"
}
检查安装的 chai 包版本：npm ls --depth=0，我认为你的版本 >= 3.
