reactjs - 模块解析失败：带有反应和 lerna 的意外令牌

Question

最近我在第一个带有 lerna monorepository 的反应项目中遇到了这个错误。所以，当我运行npm run start命令时出现此错误。就我而言，该项目在没有 lerna 的情况下可以正常运行。

E:/lerna/node_modules/pdfjs-dist/build/pdf.js 3559:145
Module parse failed: Unexpected token (3559:145)

You may need an additional loader to handle the result of these loaders.
