无法构建 angular 通用服务器，请帮助我

Question

当我尝试启动服务器时，遇到这个问题：

cmsfront@0.0.0 serve:ssr D:\PROGRAMIRANJE\CMSfrontbackup node dist/CMSfront/server/main.js

D:\PROGRAMIRANJE\CMSfrontbackup\dist\CMSfront\server\main.js:196764 抛出新错误（"package.json does not exist at " + package_json_path）； ^

错误：package.json 不存在于 D:\PROGRAMIRANJE\CMSfrontbackup\dist\CMSfront\package.json 在对象../node_modules/grpc/node_modules/node-pre-gyp/lib/pre-binding.js.exports.find (D:\PROGRAMIRANJE\CMSfrontbackup\dist\CMSfront\server\main.js:196764:15) 在对象../node_modules/grpc/src/grpc_extension.js (D:\PROGRAMIRANJE\CMSfrontbackup\dist\CMSfront\server\main.js:211850:12) 在 webpack_require (D:\PROGRAMIRANJE\CMSfrontbackup\dist\CMSfront\server\main.js:20:30) 在对象../node_modules/grpc/src/client_interceptors.js (D:\PROGRAMIRANJE\CMSfrontbackup\dist\CMSfront\server\main.js:209576:12) 在 webpack_require (D:\PROGRAMIRANJE\CMSfrontbackup\dist\CMSfront\server\main.js:20:30) 在对象../node_modules/grpc/src/client.js (D:\PROGRAMIRANJE\CMSfrontbackup\dist\CMSfront\server\main.js:208381:27) 在 webpack_require (D:\PROGRAMIRANJE\CMSfrontbackup\dist\CMSfront\server\main.js:20:30) 在对象../node_modules/grpc/index.js (D:\PROGRAMIRANJE\CMSfrontbackup\dist\CMSfront\server\main.js:191024:14) 在 webpack_require (D:\PROGRAMIRANJE\CMSfrontbackup\dist\CMSfront\server\main.js:20:30) 在对象../node_modules/@firebase/firestore/dist/index.node.cjs.js (D:\PROGRAMIRANJE\CMSfrontbackup\dist\CMSfront\server\main.js:118582:12)
错误！代码生命周期错误！错误号 1 错误！ cmsfront@0.0.0 serve:ssr: node dist/CMSfront/server/main.js 错误！退出状态 1 错误！错误！在 cmsfront@0.0.0 serve:ssr 脚本处失败。错误！这可能不是 npm 的问题。上面可能还有其他日志记录输出。

npm 错误！此运行的完整日志可在以下位置找到：错误！ C:\Users\Lenovo Z50-70\AppData\Roaming\npm-cache_logs20-04-05T14_07_24_462Z-debug.log

我看到粗体 webpack_require 但是当我安装 nguniversal 时我没有得到 webpack 配置文件。这是我的时间线：

ng 添加@nguniversal/express-engine
npm 运行 build:ssr
npm 运行 serve:ssr - 来自顶部的错误。

请帮我解决这个问题。

Answer 1

在 angular.json server.options 中添加：

"externalDependencies": [
              "grpc",
              "@grpc/proto-loader",
              "@angular/fire/firestore",
              "firebase/firestore"
            ]

在 tsconfig.json > angularCompilerOptions

中添加了这个

 "enableIvy": false

解决了我的问题，但我不知道我因假常春藤损失了多少。
