打字稿：如何解决 'rxjs/Rx 没有导出的成员 'SubscriptionLike'

Question

我正在尝试在https://www.youtube.com/watch?v=gxCu5TEmxXE 此处遵循此示例，但是在执行tsc -p 时，出现错误。有什么需要导入的吗？

错误：

node_modules/@angular/common/src/location/location.d.ts(1,10): error TS2305: Module '"...functions/node_modules/rxjs/Rx"' has no exported member 'SubscriptionLike'.

TS 文件

import "zone.js/dist/zone-node";
import * as functions from "firebase-functions";
import * as express from "express"
import { renderModuleFactory } from "@angular/platform-server"
import * as fs from "fs"

const document = fs.readFileSync(__dirname + "/dist-server/index.html", "utf8");
const AppServerModuleNgFactory = require(__dirname + "/dist-server/main.bundle");

const app = express();
app.get("**", (req, res) => {
    const url = req.path;
    renderModuleFactory(AppServerModuleNgFactory, { document, url }).then(html => {
        res.send(html);
    });
});
exports.post = functions.https.onRequest(app);

配置

{
  "compilerOptions": {
    "module": "commonjs",
    "target": "es2015",
    "rootDir": ".",
    "outDir": "../functions"
  },
  "files": [
    "index.ts"
  ]
}

Answer 1

关注后我也遇到了同样的问题

Following this tutorial from djamware

经过大量搜索，我发现Angular 6不支持通过本教程中的说明安装的Rxjs包。

Angular 6 不适用于 RxJS 5.5，但适用于 RxJS 6。

npm i rxjs@6

在 cli 中运行上述命令应该可以解决您的问题。在我的情况下确实如此。

我敢打赌，如果您查看 package.json，您会看到很多 beta angular 软件包版本。您可以降级到release version，或者，如果出于某种奇怪的原因您需要继续使用测试版，您可以编辑该location.d.ts 文件并将该文件中使用SubcriptionLike 的两个位置更改为仅@ 987654328@。同样，这是超级hacky，每次运行npm install 时都会被清除，并且只有在您出于某种原因需要使用beta 时才应该使用它。 package.json 中的依赖项应该看起来像这样（尽管我的依赖项是为 ionic 准备的）：

"dependencies": {
  "@angular/cli": "^1.7.3",
  "@angular/common": "^5.2.9",
  "@angular/compiler": "^5.2.9",
  "@angular/compiler-cli": "^5.2.9",
  "@angular/core": "^5.2.9",
  "@angular/forms": "^5.2.9",

  "@ionic-native/splash-screen": "4.4.0",

}

rxjs 的最新版本是 6.9.0 要解决此问题，您必须更新 rxjs 包。 运行ng update rxjs
