我正在尝试学习typescript，并创建了一个简单的typescript node js服务器，它有两个端点。尝试两个单元测试文件，并得到以下错误：

TSError: ⨯ Unable to compile TypeScript:
test/endpoint2.test.ts:6:7 - error TS2451: Cannot redeclare block-scoped variable 'chai_1'.

6 const chai_1 = __importDefault(require("chai"));
        ~~~~~~

  test/endpoint.test.ts:6:7
    6 const chai_1 = __importDefault(require("chai"));
            ~~~~~~
    'chai_1' was also declared here.

测试文件1（endpoint.test.ts）：

import chai from 'chai';
import chaiHttp from 'chai-http';
import { app } from '../src/index';

chai.use(chaiHttp);

describe('Endpoint tests', () => {
    it('Ping endpoint should return status 200', (done) => {
        const msg = "hello";
        chai.request(app)
            .get('/ping')
            .query({
                "message": msg
            })
            .end((err, res) => {
                chai.expect(res).to.have.status(200);
                chai.expect(res.body).to.have.property("env", "TEST")
                chai.expect(res.body).to.have.property("version", "1.0.0")
                done();
            });
    });
});

测试文件2（endpoint2.test.ts）：

import chai from 'chai';
import chaiHttp from 'chai-http';
import { app } from '../src/index';

chai.use(chaiHttp);

describe('Endpoint2', () => {
    it('Hello world endpoint should return status 200', (done) => {
        const msg = "hello";
        chai.request(app)
            .get('/')
            .end((err, res) => {
                chai.expect(res).to.have.status(200);
                done();
            });
    });
});

package.json:

tsconfig.json:

{
  "compilerOptions": {
    "target": "es6",
    "module": "commonjs",
    "esModuleInterop": true,
    "outDir": "./dist",
    "sourceMap": true,
    "moduleDetection": "auto",
    "noEmit": true
  },
  "include": [
    "./src/**/*"
  ]
}

通过package.json脚本运行测试

"scripts": {
    "test": "ts-node ./node_modules/mocha/bin/mocha --exit --require ts-node/register test/**/*.test.ts"
  },

如何告诉typescript编译器不要在不同文件中的导入上出错？
尝试：
1.在test/libs中创建了一个库文件，保存所有导入，然后将其导出到测试文件中。同样的错误。
1.尝试翻转不同的tsconfig标志，但未成功
1.尝试将'import'替换为'require'。这可以工作，但IDE警告我不要这样做。我想我应该可以使用import。
1.我所有的谷歌提示都把我带到了一个非常不同的方向。
