Javascript 在角度生产构建期间获取错误

当我准备发布项目时，我遇到了这个错误。有人能告诉我怎么解决这个问题吗

我已经修复了一些错误，但这些是关于模块的，我对这些错误一无所知。

我解决了这个问题，实际上我使用的是angular2 jwt（已弃用）以及@auth0/angular jwt。这引起了问题。因此，我卸载了带有@auth0/angular jwt的angular2 jwt更新代码，一切都开始正常工作。

我使用带有angular 6的

@auth0/angular jwt

解决了这个问题。首先需要完全卸载angular2 jwt：

npm uninstall angular2-jwt --save

然后您可以运行：

npm install @auth0/angular-jwt

---

只有这两条命令行对我有帮助。祝您一切顺利。

尝试升级您的软件包：

npm install@auth0/angular jwt

@fatemefazli我在npm install npm WARN angular2 flash期间收到这些警告-messages@2.0.5需要@angular/core@^5.0.0的对等机，但未安装任何对等机。您必须自己安装对等依赖项。npm警告角度2闪光-messages@2.0.5需要@angular/compiler@^5.0.0的对等机，但未安装任何对等机。您必须自己安装对等依赖项。npm警告角度2-jwt@0.2.3需要@angular/core@^2.0.0 | | ^4.0.0的对等机，但未安装任何对等机。您必须自己安装对等依赖项。npm警告角度2-jwt@0.2.3需要@angular/Http的对等方您是否尝试过我的命令？@fatemefazli是的，我尝试过并得到相同的错误请添加清晰的描述…以帮助我们找到根本原因和解决方案
