ng build –prod打包项目出错
错误描述：
ng build 打包正常，顺利生成dist；但在使用ng build –prod生成时提示错误：
ERROR in ./src/main.ts Module not found: Error: Can't resolve './$$_gendir/app/app.module.ngfactory' in 'D:\phpStudy\WWW\html\zxttByng\src' @ ./src/main.ts 3:0-74 @ multi ./src/main.ts
解决方法：
修改package.json中@angular/cli的版本与全局安装的@angular/cli版本保持一致。

删除node_modules文件夹以及package-lock.json，重新执行npm install 命令，安装依赖即可。注意删除package-lock.json，否则安装依赖无效，使用依旧是修改前的版本。
