js：jest报错RangeError: Maximum call stack size exceeded

问题

jest运行测试用例，使用到了​​typeof​​关键字，报错如下

RangeError: Maximum call stack size exceeded

at _typeof

问题所在

排查发现，原来是babel的问题

解决

替换依赖后就可以

1、修改 package.json 依赖

修改前

{
  "type": "module",
  "scripts": {
    "test": "jest --verbose"
  },
  "devDependencies": {
    "jest": "^29.3.1",
    "babel-jest": "^29.3.1",
    "babel-core": "^6.26.3",
    "babel-preset-env": "^1.7.0",
    "regenerator-runtime": "^0.13.11"
  }
}

修改后

{
  "type": "module",
  "scripts": {
    "test": "jest --verbose"
  },
  "devDependencies": {
    "@babel/core": "^7.20.2",
    "@babel/preset-env": "^7.20.2",
    "babel-jest": "^29.3.1",
    "jest": "^29.3.1"
  }
}

2、.babelrc修改如下

修改前

{
  "presets": ["env"]
}

修改后

{
  "presets": [
    [
      "@babel/preset-env",
      {
        "targets": {
          "node": "current"
        }
      }
    ]
  ]
}
