解决：
 1.remove package-lock.json
 2.remove node_modules
 3.npm install
                                    @ mapbox / node-pre-gyp
@ mapbox / node-pre-gyp使得从二进制文件发布和安装Node.js C ++插件变得容易
 @mapbox/node-pre-gyp介于和 @mapbox/node-pre-gyp之间，并提供跨平台的二进制部署方法。
前一包装的特别说明
在2021年2月9日@mapbox/node-pre-gyp@1.0.0被。 不属于@mapbox组织的较旧的，不受范围限制的版本已被弃用，只有@mapbox/node-pre-gyp才会看到更新。 要升级到新软件包，请执行以下操作：
 npm uninstall node-pre-gyp --save
npm install @mapbox/node-pre-gyp --save
一个名为node-pre-gyp的命令行工具，可以从二进制文件安装软件包的C ++模块。
 各种针对开
                                    二进制下载器
该模块根据给定版本的Node.js的要求下载远程二进制文件。
 它还简化了对这些模块的需求。 它旨在实现Node.js v4兼容性（这就是为什么它使用tar和semver模块的旧版本的原因）。
 该模块的目标是在无法进行本地构建时提供一种简单且轻巧的方式来处理预构建的本机模块。
npm install -S binary-downloader
此模块在package.json与node-pre-gyp相同的binary字段。 但是，它仅支持以下标签：
 platform
 node_napi_label
 对于其他标签，请随时打开问题或公关！
 另外，要获取下载的二进制文件的require字符串，您还必须执行以下操作： 
 const PackageJSON = require ( './package.json' ) ;
const bi
 与一起使用可轻松支持本机模块的prebuilds。
笔记。 预node-gyp-build@4名称在和node-gyp-build@4 node-gyp-build@4已更改。 请参阅下面的文档。
 node-gyp-build工作原理与 gyp相似，不同之处在于它将在重建项目之前检查是否存在构建或预构建。
 它的主要用途是作为本机模块的npm安装脚本和绑定加载器，这些模块使用捆绑预 。
 首先将node-gyp-build作为安装脚本添加到您的本机项目中
  "scripts" : {
    "install" : "node-gyp-build"
 然后在index.js ，而不是使用模块，而是使用node-gyp-build来加载
4.然后就报出如下错误
localhost:react-first changwei$ npm install --save react-router
npm WARN deprecated core-js@1.2.7: core-js@ fsevents@1.2.4 install /Users/changwei/project/react-first/node_modules/fsevents

原因：node-zopfli的问题，node-zopfli是compression-webpack-plugin 0.3.2版本引用的依赖
解决：compression-webpack-plugin 2.0.0没有依赖node-zopfli，切换到2.0.0版本

偶见另一方法：http://www.mamicode.com/inf
                                    感觉这个错误很常见，解决方法也很简单粗暴，像截图中说的一样，更新一下就好了，也就是重新install一下
参考：https://www.npmjs.com/package/node-pre-gyp
这里说node-pre-gyp只能全局安装
所以小伙伴们只能退出项目目录，cd回到主目录，然后执行：
sudo npm install node-pre-gyp -g
安装成功后回到你的项目目录继...
