Question

当使用Mocha运行单元测试时，我们得到以下令牌异常，指出Babel没有转换。

node_modules/expo/src/Expo.js:2
import './environment/validate';
^^^^^^

SyntaxError: Unexpected token import

mocha测试指向从expo

导入Constants的文件

import { Constants } from 'expo'

const config = Constants.manifest.extra

这是mocha opts和babel的配置方式

test/mocha.opts

--recursive
--require babel-register

.babelrc

{
  "presets": ["babel-preset-expo"],
  "env": {
    "development": {
      "plugins": ["transform-react-jsx-source"]
    }
  }
}

我刚遇到类似的错误 - 在单个文件中使用?"INSERT INTO MobileDeviceUserList(sUser, sDevice, sMobileNumber, sIMEINumber, sSerialNumber, sAccessories, sNewSIMNumber, sComments, sRecorded) " & _ "VALUES (" & Me.cboDevice & ",'" & Me.cboAccessories & ",'" & Me.txtUser & ",'" & Me.txtNumber & ",'" & Me.txtIMEI & ",'" & Me.txtSerial & ",'" & Me.txtNEWSIM & ",'" & Me.recRecorded & ",'" & _ Me.txtComment & "')"后，我的许多套件都会中断。

我通过添加

解决了我的问题

Expo.AuthSession

到我的全局模拟文件。

Babel没有使用Mocha测试来转换Expo模块
