与React-bootstrap样式进行Formik

Question

我正在尝试将formik与我的react应用使用。

我有React-Bootstrap，我正在尝试弄清楚如何使用Bootstrap样式来样式形成组件。

我的形式是：

// Render Prop
import React from 'react';
import { Link } from 'react-router-dom';
import { Formik, Form, Field, ErrorMessage } from 'formik';
import { Badge, Button, Col, Feedback, FormControl, FormGroup, FormLabel, InputGroup } from 'react-bootstrap';
import * as Yup from 'yup';
const style1 = {
    width: '60%',
    margin: 'auto'
}
const style2 = {
    paddingTop: '2em',
}
const style3 = {
    marginRight: '2em'
}
class Basic extends React.Component {
    render() {
        return (
            <Formik
                initialValues={{
                    firstName: '',
                    lastName: '',
                    email: '',
                    role: '',
                    password: '',
                    confirmPassword: '',
                    consent: false
                }}
                validationSchema={Yup.object().shape({
                    firstName: Yup.string()
                        .required('First Name is required'),
                    lastName: Yup.string()
                        .required('Last Name is required'),
                    email: Yup.string()
                        .email('Email is invalid')
                        .required('Email is required'),
                    role: Yup.string()
                        .required('It will help us get started if we know a little about your background'),    
                    password: Yup.string()
                        .min(6, 'Password must be at least 6 characters')
                        .required('Password is required'),
                    confirmPassword:  Yup.string()
                        .oneOf([Yup.ref('password'), null], 'Passwords must match')
                        .required('Confirm Password is required')
                })}
                onSubmit={fields => {
                    alert('SUCCESS!! :-)nn' + JSON.stringify(fields, null, 4))
                }}
                render={({ errors, status, touched }) => (
                    <Form style={style1}>
                    <h1 style={style2}>Get Started</h1>
                        <div className="form-group">
                            <label htmlFor="firstName">First Name</label>
                            <Field name="firstName" type="text" className={'form-control' + (errors.firstName && touched.firstName ? ' is-invalid' : '')} />
                            <ErrorMessage name="firstName" component="div" className="invalid-feedback" />
                        </div>
                        <div className="form-group">
                            <label htmlFor="lastName">Last Name</label>
                            <Field name="lastName" type="text" className={'form-control' + (errors.lastName && touched.lastName ? ' is-invalid' : '')} />
                            <ErrorMessage name="lastName" component="div" className="invalid-feedback" />
                        </div>
                        <div className="form-group">
                            <label htmlFor="email">Email</label>
                            <Field name="email" type="text" placeholder="Please use your work email address" className={'form-control' + (errors.email && touched.email ? ' is-invalid' : '')} />
                            <ErrorMessage name="email" component="div" className="invalid-feedback" />
                        </div>
                        <div className="form-group">
                            <label htmlFor="role">Which role best describes yours?</label>
                            <Field name="role" type="text"  placeholder="eg, academic, industry R&D, policy, funder" className={'form-control' + (errors.role && touched.role ? ' is-invalid' : '')} >
                            </Field>
                            <ErrorMessage name="role" component="div" className="invalid-feedback" />
                        </div>
                        <div className="form-group">
                            <label htmlFor="password">Password</label>
                            <Field name="password" type="password" className={'form-control' + (errors.password && touched.password ? ' is-invalid' : '')} />
                            <ErrorMessage name="password" component="div" className="invalid-feedback" />
                        </div>
                        <div className="form-group">
                            <label htmlFor="confirmPassword">Confirm Password</label>
                            <Field name="confirmPassword" type="password" className={'form-control' + (errors.confirmPassword && touched.confirmPassword ? ' is-invalid' : '')} />
                            <ErrorMessage name="confirmPassword" component="div" className="invalid-feedback" />
                        </div>
                        <div className="form-group">
                        <Field component="select" name="color">
  <option value="red">Red</option>
  <option value="green">Green</option>
  <option value="blue">Blue</option>
</Field>
                            <Field name="consent" label="You must accept the  and Privacy Policy"  type="checkbox" className={'form-control' + (errors.consent && touched.consent ? ' is-invalid' : '')} />
                            <ErrorMessage name="consent" component="div" className="invalid-feedback" />
                        </div>

                        <div className="form-group">
                            <Button variant="outline-primary" type="submit" style={style3}>Register</Button>
                        </div>
                    </Form>
                )}
            />
        )
    }
}
export default Basic; 

当我尝试将React-Bootstrap表格组添加到内部渲染方法时，例如：

  <Form.Group controlId="formBasicEmail">
    <Form.Label>Email address</Form.Label>
    <Form.Control type="email" placeholder="Enter email" />
    <Form.Text className="text-muted">
      We'll never share your email with anyone else.
    </Form.Text>
  </Form.Group>

我有一个错误，说：

元素类型无效：预期一个字符串(用于内置组件(或类/函数(对于复合组件(，但得到：未定义。您可能会忘记从定义的文件中导出组件，或者您可能将默认值混合并命名为导入。

检查Formik的渲染方法。

我认为此错误消息是指元素类型的意思是"电子邮件" - 但这没有任何意义不要尝试使用React-Bootstrap。

是否有人想出了如何使Formik与React-Bootstrap一起使用？

Answer 1

您正在使用错误的Form。从react-bootstrap而不是formik导入它，并且应该起作用。
