Jest-cli错误

Question

运行测试时出现两个错误。我不解决它：/

节点：v6.11.2
Npm ：v3.10.10

第一个错误是无法读取属性＆＃39;对象。＆＃39;为null

TypeError: Cannot read property 'Object.<anonymous>' of null

的package.json

  "dependencies": {
    "native-base": "^2.3.1",
    "react": "16.0.0-alpha.12",
    "react-native": "0.47.2",
    "react-native-vector-icons": "^4.3.0",
    "react-navigation": "^1.0.0-beta.11",
    "react-redux": "^5.0.6",
    "redux": "^3.7.2",
    "redux-thunk": "^2.2.0"
  },
"devDependencies": {
    "babel-cli": "^6.26.0",
    "babel-eslint": "^7.2.3",
    "babel-jest": "20.0.3",

    "enzyme": "^2.9.1",
    "jest": "20.0.4",
    "jest-react-native": "^18.0.0",

    "react-test-renderer": "^16.0.0-beta.5",
    "redux-mock-store": "^1.2.3"
  },
  "jest": {
    "preset": "react-native",
    "transformIgnorePatterns": [
      "/node_modules/(?!native-base)/",

    ]
  }

当我不使用jest --no-cache时，抛出此错误
第二次错误

/usr/lib/node_modules/jest-cli/node_modules/jest-runtime/build/index.js:510
    const wrapper = this._environment.runScript(transformedFile.script)[ ^

也许尝试类似的东西。

    "jest": {
    "verbose": true,
    "coverageDirectory": "./coverage",
    "coverageThreshold": {
        "global": {
            "branches": 40,
            "functions": 0,
            "lines": 33,
            "statements": 25
        }
    }
}

并在脚本中添加。

"test": "node ./node_modules/jest/bin/jest --coverage",
