Angular通用构建因以下错误而中断：throw Error（“不支持”）;

运行以下命令：npm run build：ssr && npm run serve：ssr运行3个不同的编译阶段，但在最后一个阶段，它将返回以下错误，导致服务器无法启动。

环境和包裹”

Angular CLI: 8.3.3
Node: 11.6.0
OS: linux x64
Angular: 8.2.5
... animations, common, compiler, compiler-cli, core, forms
... language-service, platform-browser, platform-browser-dynamic
... platform-server, platform-webworker
... platform-webworker-dynamic, router, service-worker

我的server.ts看起来如下

const PORT = process.env.PORT || 4000;
const DIST_FOLDER = join(process.cwd(), 'dist');
const domino = require('domino');
const fs = require('fs');
const path = require('path');
const template = fs.readFileSync(path.join(__dirname,   join(DIST_FOLDER, 'browser/index.html'))).toString();
const win = domino.createWindow(template);
global['window'] = win;
global['navigator'] = win.navigator;
global['Node'] = win.Node;
global['Event'] = win.Event;
global['Event']['prototype'] = win.Event.prototype;
global['document'] = win.document;
global["branch"] = null;
global['localStorage'] = localStorage;

1. Deleted problematic folder ./node_modules/@grpc/... 2. Manually uploaded a new @grpc folder with @grpc -- proto-loader ---- build/src/index.js ---- LICENCE ---- package.json
