急速模块地图中不存在急速模块“nodemailer”

Question

我正在使用 beonews pro 模板构建一个移动应用程序。我需要为联系表格添加一些电子邮件功能。所以很自然地我做了npm install nodemailer 只是看到以下错误。

Haste module 'nodemailer' does not exist in haste module map

它列出了要遵循的四个步骤

1.watchman watch-del-all
2.rm -rf node_module && yarn
3.rm -rf /tmp/metro-bundler-cache-*
4.rm -rf /tmp/haste-map-react-native-packager-*

执行上述步骤后，我仍然收到相同的错误。

import React, { PureComponent } from 'react'
import PropTypes from 'prop-types'
import { View, Text, ScrollView, TextInput, Button, Image, Animated } from 'react-native'
import wp from '@services/WPAPI'
import WebView from '@components/WebView/WebView'
import AnimatedButton from '@components/AnimatedButton/index'
import { Toolbar } from '@components'
import styles from './styles'


import nodemailer from 'nodemailer';


export default class CustomPage extends PureComponent {
  static propTypes = {
    id: PropTypes.any,
  }

  constructor(props) {
    super(props)
    this.state = {
      newsletterFName: '',

    })
    .then(response => {
      console.log('response before timeout', response);
      setTimeout(() => {
        console.log('inside timout')
        if(response.status !== 200) {
          this.setState({
            loading: false,
          })
        } else {
          this.setState({

            newsletterFName: '',
            newsletterLName: '',
            success: true
          })
        }
      }, 2000);
    });
  }
  onSubmitContactForm() {
    console.log('contact form submitted');
    let email = this.state.contactEmail;
    let first = this.state.contactFName;
    let last = this.state.contactLName;
    let msg = this.state.contactMessage;

    // async..await is not allowed in global scope, must use a wrapper
    async function main(){


      // create reusable transporter object using the default SMTP transport
      let transporter = nodemailer.createTransport({
        host: "smtp.office365.com",
        port: 587,
        secure: false, // true for 465, false for other ports
        auth: {
          user: 'xxx', // generated ethereal user
          pass: 'xxx' // generated ethereal password
        }
      });

      // send mail with defined transport object
      let info = await transporter.sendMail({
        from: '"Fred foos" <foo@example.com>', // sender address
        to: this.state.contactEmail, // list of receivers
        subject: 'News.Law Mobile Contact Form', // Subject line
        text: this.state.contactMessage, // plain text body
        html: this.state.contactMessage // html body
      });

      console.log("Message sent: %s", info.messageId);
      // Message sent: <b658f8ca-6296-ccf4-8306-87d57a0b4321@example.com>

      // Preview only available when sending through an Ethereal account
      console.log("Preview URL: %s", nodemailer.getTestMessageUrl(info));
      // Preview URL: https://ethereal.email/message/WaQKMgKddxQDoou...
    }

    main().catch(console.error);
  }
}

我希望程序包能够加载，这样我就可以根据提交的联系表单发送电子邮件。实际结果给我带来了上述错误。

在这种情况下，对我有用的是确保我在完成四个步骤后重新启动了计算机。我认为这可能与模拟器有关？但我不确定。
