在server.ts中，导入PrismaClient，如下所示：

import { PrismaClient } from '@prisma/client';

export const prisma = new PrismaClient();

使用tsc构建并运行编译的代码时抛出错误：

yarn run build && yarn run start

import { PrismaClient } from '@prisma/client';
         ^^^^^^^^^^^^
SyntaxError: Named export 'PrismaClient' not found. The requested module '@prisma/client' is a CommonJS module, which may not support all module.exports as named exports.
CommonJS modules can always be imported via the default export, for example using:

    import pkg from '@prisma/client';
    const { PrismaClient } = pkg;
    
        at ModuleJob._instantiate (internal/modules/esm/module_job.js:104:21)
        at async ModuleJob.run (internal/modules/esm/module_job.js:149:5)
        at async Loader.import (internal/modules/esm/loader.js:166:24)
        at async Object.loadESM (internal/process/esm_loader.js:68:5)
    error Command failed with exit code 1.

所以我做了建议的事情，把代码改为：

import Prisma from '@prisma/client';

const { PrismaClient } = Prisma;
export const prisma = new PrismaClient();

在用tsc编译并运行生成的代码之后，这段代码就可以工作了。但是现在用ts-node-dev运行typescript文件会抛出这个错误：

yarn run dev

TypeError: Cannot destructure property 'PrismaClient' of 'client_1.default' as it is undefined.

并将代码更改为：

import Prisma from '@prisma/client';

export const prisma = new Prisma.PrismaClient();

引发此错误：

yarn run dev

怎么会呢？我怎么能让两者同时工作呢？
