React Pdf pdf worker Path 必须是一个字符串。收到未定义的错误

Question

我正在使用 react-pdf。我的版本是；节点 version:8.9.4，react-pdf:^5.3.2，react 版本：16.3.1。我阅读文档并创建了一个组件。 (https://www.npmjs.com/package/react-pdf) 组件适用于 CDN 解决方案，但不适用于从 entry.webpack 导入文档和页面。我得到这个错误：node_modules/react-pdf/node_modules/file-loader/dist/cjs.js!./node_modules/react-pdf/node_modules/pdfjs-dist/build/pdf.worker.js 模块构建失败：类型错误：路径必须是字符串。收到未定义

我的组件是；

import { Document, Page } from 'react-pdf/dist/esm/entry.webpack'

render() {
          <Document
            file={pdf}
            onLoadSuccess={this.onDocumentLoadSuccess}
            options={options}
            rotate={this.state.rotate}
            className="document__page__main"
         >
            <Page
              object-fit="fill"
              scale={this.state.scale}
              pageNumber={this.state.pageNumber}
              width={600}
              heigth={600}
            />
          </Document>
