javascript - Redux Form 在没有错误的情况下使应用程序崩溃

Question

加载 redux 表单（来自https://github.com/erikras/redux-form-material-ui示例的代码）时，它会使应用程序崩溃，并且控制台中没有错误。这是表单的样子：

import {Component} from 'react'
import { reduxForm, Field } from 'redux-form'
import MenuItem from 'material-ui/MenuItem'
import { RadioButton } from 'material-ui/RadioButton'
import {
  Checkbox,
  RadioButtonGroup,
  SelectField,
  TextField,
  Toggle
} from 'redux-form-material-ui'

class MyForm extends Component {
  render() {
    return (
      <form>
        <Field name="username" component={TextField} hintText="Street"/>

        <Field name="plan" component={SelectField} hintText="Select a plan">
          <MenuItem value="monthly" primaryText="Monthly"/>
          <MenuItem value="yearly" primaryText="Yearly"/>
          <MenuItem value="lifetime" primaryText="Lifetime"/>
        </Field>

        <Field name="agreeToTerms" component={Checkbox} label="Agree to terms?"/>

        <Field name="receiveEmails" component={Toggle} label="Please spam me!"/>

        <Field name="bestFramework" component={RadioButtonGroup}>
          <RadioButton value="react" label="React"/>
          <RadioButton value="angular" label="Angular"/>
          <RadioButton value="ember" label="Ember"/>
        </Field>
      </form>
    )
  }
}

// Decorate with redux-form 
MyForm = reduxForm({
  form: 'myForm'
})(MyForm)

export default MyForm

然后我在父级中渲染这个 COMP。我还在 combineReducers 函数中包含了“formReducer”。
