我正在尝试用--prod构建我的应用程序，而我这样做我遇到了版本不匹配错误的问题，我认为它导致了ngx-restangular版本，我该如何解决这个问题来制作我的应用程序以prod模式运行，当我在dev模式下运行我的应用程序时，启动画面需要更多时间，因此在研究时，我得到了一个以prod模式运行应用程序的解决方案，同时这样做我得到以下错误。
我得到的错误：

答案 0 :(得分：1)
首先删除或卸载ngx-restangular，然后只需更改你的包json文件：
首先尝试从版本号前面删除 Caret（^）
"dependencies": {
"ngx-restangular": "1.0.13"
}
然后运行：
npm install
这个原因是因为，其他依赖关系或角度需要特定版本来构建项目。
我希望这会有所帮助！
