typescript - STRIPE + TypeScript : TypeError: stripe_1. 默认不是构造函数

Question

我正在我的 TypeScript MicroService 中对 Stripe 代码进行一些测试:

process.env.STRIPE_KEY = 'sk_test_...............';
import Stripe from 'stripe';
export const stripe = new Stripe(process.env.STRIPE_KEY!, {
  apiVersion: '2020-03-02',
});

但是我不断得到构造函数没有定义:

 **TypeError: stripe_1.default is not a constructor**

 1 | import Stripe from 'stripe';
> 2 | export const stripe = new Stripe(process.env.STRIPE_KEY!, {
    |                       ^
  3 |   apiVersion: '2020-03-02',
  4 | });
  5 |

我怀疑你正在服用Stephen Grider's microservices course .
你重命名了src/__mocks__/stripe.ts至src/__mocks__/stripe.ts.old ?
这看起来像 TS 正在针对模拟 strip 模块，而不是真正的 strip 模块。确保删除(或重命名)src/__mocks__/stripe.ts .
如果模拟 strip 文件名与模块相同，则 jest 将使用模拟 strip 。请注意，即使您删除了 jest.mock('../../stripe');，这也适用
来自 jest documentation :

When a manual mock exists for a given module, Jest's module system will use that module when explicitly calling jest.mock('moduleName'). However, when automock is set to true, the manual mock implementation will be used instead of the automatically created mock, even if jest.mock('moduleName') is not called. To opt out of this behavior you will need to explicitly call jest.unmock('moduleName') in tests that should use the actual module implementation.
