在 docker 中构建 Nextjs 出现 Prisma 错误答案

【问题描述】：

我正在 nest.js 中构建一个应用程序，然后我想通过使用 docker 将其 dockerize，这是我的 docker 文件：

FROM node:14 AS builder

# Create app directory
WORKDIR /app

# A wildcard is used to ensure both package.json AND package-lock.json are copied
COPY package*.json ./
COPY prisma ./prisma/

# Install app dependencies
RUN npm install

COPY . .

RUN npm run build

FROM node:14

COPY --from=builder /app/node_modules ./node_modules
COPY --from=builder /app/package*.json ./
COPY --from=builder /app/dist ./dist

EXPOSE 3000
CMD [ "npm", "run", "start:prod" ]

然后当我运行时：

docker build -t medicine-api .

我从 prisma 收到了这个错误

Module '"@prisma/client"' has no exported member 'User'.

3 import { User } from '@prisma/client';

这是我的 prisma.schema 文件

/ This is your Prisma schema file,
// learn more about it in the docs: https://pris.ly/d/prisma-schema

generator client {
  provider = "prisma-client-js"
}

generator prismaClassGenerator {
  provider = "prisma-class-generator"
  dryRun   = false
}

datasource db {
  provider = "postgresql"
  url      = env("DATABASE_URL")
}

model User {
  id               Int                @id @default(autoincrement())
  phoneNumber      String             @unique
  lastName         String
  firstName        String
  role             Role
  bio              String?
  certificate      String?
  pic              String?
  verified         Boolean            @default(false)
  medicine         Medicine[]
  pharmacyMedicine PharmacyMedicine[]
  medicineCategory MedicineCategory[]
  pharmacyPackage  PharmacyPackage[]
  pharmacistOrder  Order[]            @relation("pharmacistOrder")
  userOrder        Order[]            @relation("userOrder")
}

我尝试通过搜索不同的资源和网站来解决此问题，然后他们建议我将 npx prisma generate 放入我的 dockefil。但我仍然在这里遇到另一个错误：

Error: Generator at prisma-class-generator could not start:

/bin/sh: 1: prisma-class-generator: not found

如果您有任何解决方案，我很乐意尝试。提前致谢。

【问题讨论】：

错误何时发生，在构建过程的哪个步骤？
RUN npm run build，这一步报错
您的 package.json 文件是什么样的？好像你安装了 prisma 而没有将它作为依赖项出现在 package.json 文件中
gist.github.com/seabnavin19/eb6b6862732b1b025cb37463a1515e78，在这里
你找到解决办法了吗？当前从@prisma/client 导出的所有类型都存在相同的问题

【解决方案1】：

您必须通过运行命令生成 prisma 客户端

yarn prisma generate

这应该在处理 prisma 文件夹之前所以我建议将 dockerFile 更改为

FROM node:14 AS builder

# Create app directory
WORKDIR /app

# A wildcard is used to ensure both package.json AND package-lock.json are copied
COPY package*.json ./

# Install app dependencies
RUN npm install

COPY . .

RUN yarn prisma generate
COPY prisma ./prisma/


RUN npm run build

FROM node:14

COPY --from=builder /app/node_modules ./node_modules
COPY --from=builder /app/package*.json ./
COPY --from=builder /app/dist ./dist

EXPOSE 3000
CMD [ "npm", "run", "start:prod" ]

prisma generate 步骤将确保您的 node_modules 中有 prisma 客户端，以便它可用于迁移 prisma 模型
