无法解析源映射...错误：ENOENT：没有这样的文件或目录

Question

问题是当我运行yarn start 时出现一些警告：

WARNING in ./node_modules/@usedapp/core/dist/esm/src/providers/transactions/reducer.js
Module Warning (from ./node_modules/source-map-loader/dist/cjs.js):

Use 'stats.errorDetails: true' resp. '--stats-error-details' to show it.

我通过运行npx create-react-app frontend --template typescript 命令创建了react 应用程序。还有与我几乎相同的issue。但它没有解决。

Answer 1

您应该尝试在根目录（与 package.json 相同的文件夹）中创建一个 .env 文件，并将 GENERATE_SOURCEMAP=false 设置在一行：

GENERATE_SOURCEMAP=false

Answer 2

最近更新0.11 的@usedapp/core 库解决了这个问题。
