在开玩笑时出现以下错误。我不知道为什么会收到此错误。
@ grpc / proto-loader / node_modules / protobufjs / ext / descriptor / index.js（文件）
"use strict";
var $protobuf = require("../..");
module.exports = exports = $protobuf.descriptor = $protobuf.Root.fromJSON(require("../../google/protobuf/descriptor.json")).lookup(".google.protobuf");
测试套件无法运行
TypeError：无法读取未定义的属性'fromJSON'
