Function findFromNodeModules

opensca/sca/javascript/npm.go:393–409

findFromNodeModules 从node_modules中查找使用的package.json name: 查找的组件名 basedir: 当前package.json所在路径 nodePathMap: node_modules中package.json文件的目录映射 例/node_modules/demo jspath: 查找到的package.json所在目录 js: 查找到的package.json

(name, basedir string, nodePathMap map[string]*PackageJson)

// jspath: 查找到的package.json所在目录
// js: 查找到的package.json
