node.js - 为什么我可以构建我的 React 应用程序但无法启动它

Question

将 rehype-katex 从 5.0.0 升级到 6.0.1 后，当我运行 yarn start ，我得到了:

./node_modules/hast-util-to-text/index.js 363:65
Module parse failed: Identifier directly after number (363:65)
File was processed with these loaders:
 * ./node_modules/react-scripts/node_modules/babel-loader/lib/index.js
You may need an additional loader to handle the result of these loaders.
|     //     break is the zero-width space character (U+200B), then the break is
|     //     removed, leaving behind the zero-width space.
>     if (lines[index].charCodeAt(lines[index].length - 1) === 0x20_0b
|     /* ZWSP */
|     || index < lines.length - 1 && lines[index + 1].charCodeAt(0) === 0x20_0b

但它在 codesandbox 中工作正常, yarn build 也可以。我该如何解决这个问题？

我的 package.json:

我遇到了完全相同的问题，并通过以下 SO POST 解决了这个问题:https://stackoverflow.com/a/67574280/16766691

只需转到项目根文件夹下的 package.json，

替换

"browserslist": {
    "production": [
      ">0.2%",
      "not dead",
      "not op_mini all"
    ],
    "development": [
      "last 1 chrome version",
      "last 1 firefox version",
      "last 1 safari version"
    ]
  }

与

  "browserslist": [
      ">0.2%",
      "not dead",
      "not op_mini all"
    ]

然后重新编译你的项目。
