Angular 6 Viele Fehler können nicht behoben werden (Krypto, FS, http, https, Netz, Pfad, Stream, TLS, ZLIB)

Ich baue eine Angular 6-App, aber jedes Mal, wenn ich localhost dienen möchte, erhalte ich folgende Fehler:

Weiß jemand, was schief läuft? Keines der oben genannten Module ist in meiner node_modules-Datei vorhanden (ich kann einige davon installieren, aber "crypto" ist zum Beispiel jetzt eingebaut). Wie kann ich diese Ordner bekommen? Es macht mich verrückt.

Dies wird durch Abhängigkeiten verursacht, die Knotenmodule importieren, die im Browser nicht verfügbar sind. Fügen Sie Ihrer package.json die fehlerhaften Module hinzu:

"browser": {
    "http": false,
    "https":false,
    "net": false,
    "path": false,
    "stream": false,
    "tls": false
}

Sie verwenden die neueste Version von Angular CLI. Einige npm-Pakete werden nicht mehr unterstützt. Es ist jetzt ein integriertes Knotenmodul. Wenn Sie auf Krypto angewiesen sind, sollten Sie zu dem integrierten wechseln.

Um das Problem mit Crypto zu beheben, streamen Sie die Libs.

node_modules/@angular-devkit/build-angular/src/angular-cli-files/models/webpack-configs/browser.js

datei und führen Sie die folgende Änderung durch,

`node: {crypto: true, stream: true}`

Sie können dieses Problem durch eine Benutzer-Patch-Datei lösen.

patch.js

    const fs = require('fs');
const f = 'node_modules/@angular-devkit/build-angular/src/angular-cli-files/models/webpack-configs/browser.js';

fs.readFile(f, 'utf8', function (err,data) {
  if (err) {
    return console.log(err);
  }
  var result = data.replace(/node: false/g, 'node: {crypto: true, stream: true}');

  fs.writeFile(f, result, 'utf8', function (err) {
    if (err) return console.log(err);
  });
});

packege.json

"scripts": {
"ng": "ng",
"start": "ng serve",
"build": "node patch.js && ng build",
"build-prod": "node patch.js && ng build --configuration=production",
"build-staging": "node patch.js && ng build --configuration=staging"

}

stellen Sie sicher, dass Sie den Code "erstellen", bevor Sie "ng serve" nur zum ersten Mal ausführen.

Sie müssen die Knotenpakete finden, die als Abhängigkeiten hinzugefügt wurden, die dieses Problem verursachen. Öffnen Sie package-lock.json. Die Suche nach Crypto kann die Kette von Abhängigkeiten finden, die zu dem Paketnamen führen, der im Abhängigkeitenabschnitt von package.json enthalten ist. In meinem Fall wurden die meisten dieser Bibliotheken mit dem npm-Paket 'request' eingespielt.

In der aktuellen Version von Angular-cli werden einige Pakete wie zlib nicht installiert. Möglicherweise müssen Sie einige Pakete manuell installieren, um diese Fehler zu beheben.

Verwenden Sie das Paket ngx-build-plus - https://github.com/manfredsteyer/ngx-build-plus - und geben Sie die zusätzliche Konfiguration an. Auf diese Weise müssen Sie die Knotenmodul-Dateien nicht jedes Mal manuell aktualisieren, wenn Sie eine Installation durchführen.
