【中文标题】如何解决[重复]的生产构建问题【英文标题】：How to solve production build issue of [duplicate] 【发布时间】：2021-04-22 12:02:23 【问题描述】：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，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。

在我输入命令“ng build --prod”之后 在这样完成 92% 后它引发了错误
【问题讨论】：
尝试删除你的 node_modules 并运行 npm i。似乎 angular 没有找到 node-rsa 的 nodemodules。 【参考方案1】：你提到
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 进行检查。
将 angular.json 中的 aot 标志设置为 true，以启用 head of time 编译。
再次服务应用，你一定看到了问题。
对于
Field 'browser' doesn't contain a valid alias configuration
错误见this post
【讨论】：
对不起，先生，我写错了 10 而不是 8。这是一个 Angular 8 应用程序 我删除了 2 次 node-modules 并再次安装它，但仍然出现同样的错误 添加你的 angular.json 文件？ 我已经添加了我的 angular.json 文件 检查更新的答案【参考方案2】：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
