如何解决生产构建问题
我已经创建了我的 Angular 8 应用程序。 在命令 ng serve 应用程序运行顺利没有任何错误和代码正常工作，但是， 当我为生产创建构建时，我得到了如下所示的错误图像。
我使用 node-rsa 包来加密和解密我的数据，但我无法为生产服务器构建项目，我不知道这些错误是如何引发的。< /p>

答案 0 :(得分：0)
你提到
<块引用>我已经创建了我的 Angular 10 应用程序
但是 package.json 显示了一个 angular 8 应用程序？？？
第一行错误是：node-modules doesn't exist
你确定 npm 包安装成功了吗？
再次使用 npm install 检查。
将 angular.json 中的 aot 标志设置为 true，以启用 head of time 编译。
再次提供应用程序，您必须看到问题。
为了
Field 'browser' doesn't contain a valid alias configuration
错误见this post
答案 1 :(得分：0)
我找到了这些相关问题/错误/错误的答案，
通过添加package.json
"browser": {
"path": false,
"stream": false,
"tls": false,
"crypto": false,
"constants": false
}
