誰かが何が間違っているのか知っていますか?上記のモジュールは、node_modulesファイルに存在しません(それらのいくつかをインストールできますが、たとえば、「crypto」は現在組み込まれています)。これらのフォルダを取得するにはどうすればよいですか?それは私を夢中にさせています。
これは、ブラウザで使用できないノードモジュールをインポートする依存関係が原因です。 package.jsonにエラーを与えるモジュールを追加します。
"browser": {
"http": false,
"https":false,
"net": false,
"path": false,
"stream": false,
"tls": false
}
最新バージョンのAngular CLIを使用しています。一部のnpmパッケージはサポートされなくなりました。これは、組み込みのNodeモジュールです。暗号に依存している場合は、組み込みの暗号に切り替える必要があります。
暗号に関する問題を修正するには、ライブラリをストリーミングして、
node_modules/@angular-devkit/build-angular/src/angular-cli-files/models/webpack-configs/browser.js
ファイルして、次の変更を行います。
`node: {crypto: true, stream: true}`
パッチファイルを使用して、この問題を解決できます。
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);
});
});
package.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"
}
「ng serve」の前に初めてコードを「build」してください。
Ngx-build-plusパッケージを使用します- https://github.com/manfredsteyer/ngx-build-plus -追加の構成を提供します。この方法では、インストールを行うたびにノードモジュールファイルを手動で更新する必要はありません。
この問題の原因となっている依存関係として追加されたノードパッケージを見つける必要があります。 package-lock.jsonを開き、cryptoを検索すると、package.jsonの依存関係セクションに含まれるパッケージ名につながる依存関係のチェーンを見つけることができます。私の場合、これらのライブラリのほとんどはnpmパッケージ 'request'で取り込まれました。
Angular-cliの現在のバージョンは、古いバージョンが行っていたzlibなどのパッケージをインストールしません。これらのエラーを解決するには、いくつかのパッケージを手動でインストールする必要がある場合があります。
