ng-packagrがパッケージをビルドできません。予期しないトークンエラー：予期しないトークンrollup.js

Question

角度モジュールを別のnpmモジュールとしてエクスポートしようとしています。

だから私は "packagr"（NPMでそれをやろうとしている：すべては "FESM15にコンパイル" まで良い起こっている "NG-packagr -p NG-package.json"

：

私は下にログを貼り付けます。

"compileOnSave": false, 
    "compilerOptions": { 
    "outDir": "./dist/out-tsc", 
    "sourceMap": true, 
    "declaration": false, 
    "moduleResolution": "node",

    ], 
    "lib": [ 
     "es2017", 
     "dom" 
    ] 
    } 
}

そして、私のpackage.json以下tsconfig.json

ng-packagr -p ng-package.json

なぜパッケージがビルドしたくないのでしょうか。モジュールを正常にビルドする（npmをビルドする）とき、あるいはプロダクション（npmをビルドする--prod）の場合でも、すべて正常に動作するようです。

ありがとうございました。

Answer 1

私は同じ問題がありました。エラーに記載されているモジュールをng-package.jsonの外部リストに追加して解決しました。つまり：

{ 
    "$schema": "./node_modules/ng-packagr/ng-package.schema.json", 
    "lib": { 
    "entryFile": "public_api.ts", 
    "externals": { 
     "jsdom": "jsdom", 
     "tough-cookie": "tough-cookie" 
     // etc (or maybe you can localize the module that is using 
     // them and use that module instead) 
    } 
    } 
}
