DeepSeek-OCR-WEBUI效果展示：复杂背景文字识别实测

setup

安装 Prisma CLI开发依赖npminstallprisma --save-dev

安装 Prisma Client运行时依赖npminstallprisma/client

初始化 Prisma 项目使用 npx prisma init 命令初始化 Prisma 项目。

该命令会在项目根目录下创建一个 prisma 文件夹并生成一个 schema.prisma 文件。

默认创建是postgresqlnpx prisma init

1指定数据库为sqlitenpx prisma init --datasource-provider sqlite

2把默认数据更改成sqlite

更改文件schema.prisma 内容如下generator client {provider “prisma-client-js”url env(“DATABASE_URL”)}datasource db {provider “sqlite”}

更改环境文件(.env)内容如下DATABASE_URL“file:./dev.db”表示在当前目录下创建dev.db文件

数据配置更改在.env文件更改相应信息DATABASE_URL“postgresql://johndoe:randompasswordlocalhost:5432/mydb?schemapublic”vscode 按装插件输入:prisma,截图如下

定义数据模型model User{idInt id default(autoincrement())email String unique name String?}然后执行命令npx prisma migrate dev --name init

更改或添加模型每次修改模型后都需要重新生成客户端代码npx prisma generate

启动数据库npx prisma studio录入三笔数据效果如图下

其它问题

prisma.config.ts中的process 提示不存在npm install --save-dev types/node

执行main.js 文件报错: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:解决方法一import pkg from ‘prisma/client’;const { PrismaClient } pkg;解决方法二修改 package.json加入{type:module}然后就可以正常使用命名导入import{PrismaClient}fromprisma/client;exportconst prismanew PrismaClient();方法三动态导入const{PrismaClient}await import(prisma/client);exportconst prismanew PrismaClient();

错误信息如下D:\workspace\node\ormPrismanpm run dev main
