How to use the @dcloudio/uni-cli-shared.parsePagesJson function in @dcloudio/uni-cli-shared

module.exports = function (content) {
  this.cacheable && this.cacheable()

  const pagesJsonJsPath = path.resolve(process.env.UNI_INPUT_DIR, pagesJsonJsFileName)
  const manifestJsonPath = path.resolve(process.env.UNI_INPUT_DIR, 'manifest.json')
  const manifestJson = parseManifestJson(fs.readFileSync(manifestJsonPath, 'utf8'))

  this.addDependency(pagesJsonJsPath)
  this.addDependency(manifestJsonPath)

  const pagesJson = parsePagesJson(content, {
    addDependency: (file) => {
      (process.UNI_PAGES_DEPS || (process.UNI_PAGES_DEPS = new Set())).add(normalizePath(file))
      this.addDependency(file)
    }
  })
  // TODO 与 usingComponents 放在一块读取设置
  if (manifestJson.transformPx === false) {
    process.UNI_TRANSFORM_PX = false
  } else {
    process.UNI_TRANSFORM_PX = true
  }

  if (process.env.UNI_PLATFORM === 'h5') {
    return require('./platforms/h5')(pagesJson, manifestJson)
  }

}

  if (process.env.UNI_USING_COMPONENTS || process.env.UNI_PLATFORM === 'h5') {
    return require('./index-new').call(this, content)
  }

  this.cacheable && this.cacheable()

  const pagesJsonJsPath = path.resolve(process.env.UNI_INPUT_DIR, pagesJsonJsFileName)
