使用 ng-packagr/angular 构建时出错

Question

我正在使用 Angular 7 并使用 ng-packagr 构建一个库。

升级到最新版本的 ng-packagr 和 lodash 后，出现此错误

ERROR: 'isString' is not exported by node_modules\lodash\lodash.js
'isString' is not exported by node_modules\lodash\lodash.js

知道如何解决吗？

Answer 1

对我有用的是替换

import { isString } from "lodash";

和

import { isString } from "lodash-es";

使用 ng-packagr/angular 构建时出错

Error when building with ng-packagr/angular

rollupjs

angular

ng-packagr
