headers.js 中缺少类属性转换

Question

如何解决这个问题？

Failed to compile.

C:/Users/nick_/VSCodeProjects/nft-school-examples/end-to-end/node_modules/hardhat/node_modules/undici/lib/fetch/headers.js

我添加了babel.config.js，但还是一样

module.exports = {
    presets: ["@expo/next-adapter/babel"],
    overrides: [
      {
        test: "./node_modules/@expo/next-adapter/document.js",
        plugins: [["@babel/plugin-proposal-class-properties"]],
      },
    ],
  }

我的包.json

"devDependencies": {
    "@babel/plugin-proposal-class-properties": "^7.18.6",
    "@nomiclabs/hardhat-ethers": "npm:hardhat-deploy-ethers",
    "ethers": "^5.7.2",
    "hardhat": "^2.12.6"
  },

根据您的 babel 配置，您正在尝试为 @expo 模块中的某些文件应用插件：

...
 test: "./node_modules/@expo/next-adapter/document.js",
...

但似乎你在不同的模块中有错误 -安全帽.

尝试更改引发错误的模块的路径。

[更新]

//babel.config.js
module.exports = {
    presets: ["@expo/next-adapter/babel"],
    overrides: [
      {
        test: "module where issue was thrown",
        plugins: [["@babel/plugin-proposal-class-properties"]],
      },
    ],
  }
