步骤：npm test

错误：＆＃34;意外的保留字＆＃34;

我今天早些时候有这个工作，我不知道我改变了什么可能导致回归。当我运行npm test时，我得到了＃34;意外的保留字＆＃34;它指向ES6导入语句。我的理解是--compilers js:babel-register应该解决这个问题。

我尝试在全局和本地安装babel-core并使用babel-core/register代替。结果相同。

这是我的package.json。

{
  "name": "fresh",
  "version": "0.0.1",
  "private": true,
  "scripts": {
    "remotedev": "remotedev --hostname=localhost --port=8000",
    "start": "node node_modules/react-native/local-cli/cli.js start",
    "test": "mocha --compilers js:babel-register 'test/**/*.test.js'",
    "test:watch": "npm run test -- --watch --watch-extensions jsx"
  },
  "dependencies": {
    "immutable": "^3.7.6",
    "lodash": "^4.5.1",
    "ramda": "^0.19.1",
    "react-native": "^0.21.0",
    "react-native-router-flux": "^2.3.8",
    "react-native-sortable-listview": "0.0.5",
    "react-redux": "^4.4.0",
    "redux": "^3.3.1",
    "redux-saga": "^0.9.1",
    "reselect": "^2.0.3"
  },
  "devDependencies": {
    "babel-register": "^6.7.2",
    "chai": "^3.5.0",
    "chai-immutable": "^1.5.3",
    "mocha": "^2.4.5",
    "redux-devtools-filter-actions": "^1.1.0",
    "remote-redux-devtools": "^0.1.2",
    "remotedev-server": "0.0.3"
  }
}

以下是2个教程，表明这应该有用。

同样，我今天早些时候使用此脚本成功执行了测试。

Answer 1

npm install babel-preset-es2015

然后使用

创建.babelrc文件

{
  "presets": ["es2015"]
}

运行mocha测试会导致＆＃34;意外的保留字＆＃34;错误
