Question

我使用create-react-app创建我的应用程序，然后使用NPM安装了一些我想使用的软件包。当我使用npm start run时，一切运行正常，并且没有任何错误。但是，当我尝试使用npm run build时，出现以下错误：

Creating an optimized production build...
Failed to compile.

Cannot read property 'length' of undefined


npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! runner@0.1.0 build: `react-scripts build`
npm ERR! Exit status 1
npm ERR!
npm ERR! Failed at the runner@0.1.0 build script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

npm ERR! A complete log of this run can be found in:
npm ERR!     C:\Users\Me\AppData\Roaming\npm-cache\_logs\2019-04-29T21_10_16_413Z-debug.log

当我查看日志时，找不到任何指向故障排除的信息。我检查了代码，在任何地方都不使用任何长度变量。我假设故障在其他地方，但是我什至不知道从哪里开始寻找。这很奇怪，因为当我使用npm run start时它可以工作。

这是我的package.json：

{
  "name": "runner",
  "version": "0.1.0",
  "private": true,
  "dependencies": {
    "react": "^16.8.2",
    "react-dom": "^16.8.2",
    "react-scripts": "2.1.5",
    "react-bootstrap": "1.0.0-beta.8",
    "react-timeseries-charts": "0.15.5",
    "pondjs": "0.8.10",
    "bootstrap": "4.3.1"
  },
  "scripts": {
    "start": "react-scripts start",
    "build": "react-scripts build",
    "test": "react-scripts test",
    "eject": "react-scripts eject"
  },
  "eslintConfig": {
    "extends": "react-app"
  },
  "browserslist": [
    ">0.2%",
    "not dead",
    "not ie <= 11",
    "not op_mini all"
  ]
}

如何调试react-scripts运行build errno1
