我正在尝试运行Jest测试,但是我收到以下错误:

读取文件时出错:/Users/mike/dev/react/TestTest/node_modules/react-native/node_modules/yeoman-environment/node_modules/globby/node_modules/glob/node_modules/path-is-absolute/package.json /Users/mike/dev/react/TestTest/node_modules/jest-cli/node_modules/node-haste/lib/loader/ResourceLoader.js : 88 throw err; ^

错误:EMFILE:打开文件太多,打开'/ Users/mike/dev/react/TestTest/node_modules/react-native/node_modules/yeoman-environment/node_modules/globby/node_modules/glob/node_modules/path-is-absolute/package.json'at Error(native)npm ERR!测试失败.请参阅上文了解更多详情.

我感兴趣的是错误中列出的路径指向node_modules目录中的文件,由于testPathIgnorePatterns中的node_modules条目,我预期不会读取该文件.

我正在运行Node 4.2.1,我的React-Native安装只有一周了,我今天安装了Jest(所以我觉得我已经掌握了所有内容).我在Mac上.

我已经运行:sudo ulimit -n 10240,关闭所有终端窗口,甚至尝试重启.(在我之前添加的.bash_profile中ulimit -n 1024.我尝试过更大的数字.

为了确保问题不仅仅出现在我自己的项目中,我创建了一个新项目react-native init TestTest并对RN.json进行了RN建议的更改:

{
  "name": "TestTest",
  "version": "0.0.1",
  "private": true,
  "scripts": {
    "start": "node_modules/react-native/packager/packager.sh",
    "test": "jest"
  },
  "dependencies": {
    "react-native": "^0.14.1"
  },
  "jest": {
    "scriptPreprocessor": "node_modules/react-native/jestSupport/scriptPreprocess.js",
    "setupEnvScriptFile": "node_modules/react-native/jestSupport/env.js",
    "testPathIgnorePatterns": [
      "/node_modules/",
      "packager/react-packager/src/Activity/"
    ],
    "testFileExtensions": [
      "js"
    ],
    "unmockedModulePathPatterns": [
      "promise",
      "source-map"
    ]
  },
  "devDependencies": {
    "jest-cli": "^0.7.1"
  }
}

但我每次都得到同样的错误.
