Leaflet源码是怎么打包的？

使用npm build、build、npm run-scripts build都失败了。。

我是使用的Leaflet-master下载的github仓库啊

 

使用npm install？npm install和npm run build的区别？

当运行npm install之后，在node_modules下下载了很多依赖库

但是使用"build": "npm run rollup && npm run uglify",失败了

看上面的提示，npm ERR! leaflet@1.7.1 rollup:'rollup -c build/rollup-config.js'，查看build/rollup-config.js。。如何调试呢？怎么知道问题出在哪里？
