我正在尝试使用笑话来模拟我的axios请求。这是我的测试：
// External imports
import axios, { AxiosPromise } from 'axios'
// Personal imports
import { getProgramApplications } from '#stores'
import { programItem } from '../fixtures/zanox'
describe('Zanox sales', async function () {
describe('Get program applications', async function () {
it('should get program applications', async function () {
const program = programItem()
const mock = jest.spyOn(axios, 'get')
mock.mockReturnValueOnce({ data: [program] } as unknown as AxiosPromise<unknown>)
getProgramApplications(process.env.ZANOX_ADSPACE!)
})
})
})
这是我的package.json：

}
},

问题是：当我尝试编译项目时，终端会说：

我发现有关它的大部分讨论都说要升级typescript版本并从项目中删除jasmine。如您所见，我的项目中没有jasmine，而我的typescript版本是最新的。为什么会这样？
答案 0 :(得分：0)
一种解决方案是跳过检查外部项目的类型。在您的tsconfig.json中：
{
"compilerOptions": {
....
"skipLibCheck": true
}
}
