ionic-framework - 如何在Ionic 3中使用PayPal修复“Object(…)不是函数错误”

Question

我在Ionic应用程序中工作，并且在Ionic应用程序中使用了PayPal。

这是我的checkout.ts：

import { PayPal, PayPalPayment, PayPalConfiguration } from '@ionic-native/paypal/ngx';

constructor(private PayPalMobile: PayPal) { }

makepaymentp()
  {
    //console.log("Payment");
    this.PayPalMobile.init({
      PayPalEnvironmentProduction: 'YOUR_PRODUCTION_CLIENT_ID',
      PayPalEnvironmentSandbox: 'asasasasasasasasasas',
    }).then(() => {
      // Environments: PayPalEnvironmentNoNetwork, PayPalEnvironmentSandbox, PayPalEnvironmentProduction
      this.PayPalMobile.prepareToRender('PayPalEnvironmentSandbox', new PayPalConfiguration({
        // Only needed if you get an "Internal Service Error" after PayPal login!
        //payPalShippingAddressOption: 2 // PayPalShippingAddressOptionPayPal
      })).then(() => {
        let payment = new PayPalPayment('3.33', 'INR', 'Description', 'sale');
        this.PayPalMobile.renderSinglePaymentUI(payment).then(() => {
          // Successfully paid

          // Example sandbox response
          //
          // {
          //   "client": {
          //     "environment": "sandbox",
          //     "product_name": "PayPal iOS SDK",
          //     "paypal_sdk_version": "2.16.0",
          //     "platform": "iOS"
          //   },
          //   "response_type": "payment",
          //   "response": {
          //     "id": "PAY-1AB23456CD789012EF34GHIJ",
          //     "state": "approved",
          //     "create_time": "2016-10-03T13:33:33Z",
          //     "intent": "sale"
          //   }
          // }
        }, () => {
          // Error or render dialog closed without being successful
        });
      }, () => {
        // Error in configuration
      });
    }, () => {
      // Error in initialization, maybe PayPal isn't supported or something else
    });

  }

这是我的checkout.html：

<button class="myaddto22" [disabled]="!RadioValue" (click)="makepaymentp()" full ion-button round="true">
      Make Payment
</button>

这是我的app.module.ts：

import { PayPal } from '@ionic-native/paypal/ngx';

providers: [PayPal]

我已经导入了运行PayPal所需的所有内容，但是当我运行PayPal代码时却显示错误。


  Object（...）不是PayPal.init的函数（index.js：28）


任何帮助深表感谢。

由于使用的是Ionic v3，因此应从import而不是PayPal从'@ionic-native/paypal' '@ionic-native/paypal/ngx'。

如果使用PayPal安装npm install @ionic-native/paypal，请使用npm uninstall @ionic-native/paypal卸载它，然后使用npm install --save @ionic-native/paypal@4重新安装。
