容器化我的 NodeJS 应用程序后找不到我的 pnpm 文件，我该如何解决这个问题？

Question

我是 Docker 和 NodeJS 新手，我有一个正在尝试容器化的应用程序，但是当我尝试在 docker 环境中加载该应用程序时，它会抛出此错误：

app-1      | node:internal/modules/cjs/loader:1148
app-1      |   throw err;
app-1      |   ^
app-1      | 
app-1      | Error: Cannot find module '/usr/src/app/pnpm'
app-1      |     at Module._resolveFilename (node:internal/modules/cjs/loader:1145:15)
app-1      |     at Module._load (node:internal/modules/cjs/loader:986:27)
app-1      |     at Function.executeUserEntryPoint [as runMain] (node:internal/modules/run_main:174:12)
app-1      |     at node:internal/main/run_main_module:28:49 {
app-1      |   code: 'MODULE_NOT_FOUND',
app-1      |   requireStack: []
app-1      | }
app-1      | 
app-1      | Node.js v20.13.1

下面是我的 Dockerfile 和

docker-compose.yml

文件：

Dockerfile：

FROM node:20.13.1-bookworm-slim as base

WORKDIR /usr/src/app

COPY package.json pnpm-lock.yaml* ./

RUN apt-get update && \
 apt-get install -y openssl

RUN npm install -g npm@latest && \
 npm install -g pnpm  && \
 pnpm install && pnpm --version && \
    echo "PNPM Path: $(which pnpm)"

COPY . .

RUN which pnpm

RUN pnpx prisma generate --schema=src/prisma/schema.prisma

RUN pnpm run build

# Production stage
FROM node:20.13.1-bookworm-slim as final

WORKDIR /usr/src/app

COPY --from=base /usr/src/app/dist ./dist
COPY --from=base /usr/src/app/node_modules ./node_modules
COPY --from=base /usr/src/app/package.json ./



CMD ["pnpm", "run", "dev"]

docker-compose.yml

文件：

version: '3.8'

services:
  app:
    build:
      context: .
      dockerfile: Dockerfile
    ports:
      - "5000:5000"  
    env_file:
       - .env
    volumes:
      - .:/usr/src/app
      - /usr/src/app/node_modules  
    depends_on:
      - db  
    

  db:
    image: postgres:16
    environment:
      POSTGRES_USER: postgres
      POSTGRES_PASSWORD: ${DB_PASSWORD}
      POSTGRES_DB: ${DB_NAME}
    volumes:
      - db-data:/var/lib/postgresql/data  
    healthcheck:
      test: [ "CMD-SHELL", "pg_isready -U postgres -d ${DB_NAME}" ]
      interval: 5s
      timeout: 10s
      retries: 5

  pgadmin:
      image: dpage/pgadmin4
      environment:
        - [email protected]
        - PGADMIN_DEFAULT_PASSWORD=admin
      ports:  
        - "5040:80"

volumes:
  db-data:

# DB_HOST=localhost
# DB_PORT=5432
# DB_NAME=shuttle
# DB_USER=postgres
# DB_PASSWORD=2030

现在，一开始当我收到这个错误时，我认为这可能是我的

pnpm

在docker环境中安装的方式，所以我尝试在启动容器时添加安装

pnpm

的命令，如下所示：

 dockerfile 中的 CMD ["npm install pnpm && pnpm install && pnpm run dev"] to the 

CMD` 行，但它没有帮助，它所做的只是运行安装并给了我这个：

app-1      | 
app-1      | removed 25 packages, and changed 74 packages in 54s
app-1      | 
app-1      | 22 packages are looking for funding
app-1      |   run `npm fund` for details
app-1 exited with code 0

这不是我想要的。我必须尝试更新我的

docker-compose.yml

文件以包含命令，但它仍然做同样的事情。我在某处读到，我不应该向 CMD 或命令脚本添加太多命令，但是删除所有内容让我回到最初的错误消息。

有人可以帮我理解我做错了什么吗，我已经这样做了两天了，谢谢。

对我有用的是：

ENV PNPM_HOME="/pnpm"
ENV PATH="$PNPM_HOME:$PATH"

RUN apt-get update && apt-get install -y python3 build-essential openssl
ENV PYTHON=/usr/bin/python3

# Enable corepack for package management (including pnpm)
RUN corepack enable && corepack prepare [email protected] --activate

# Set the working directory
WORKDIR /usr/src/app

# Production dependencies fetch stage
FROM base as prod

# Copy only necessary files for installing dependencies
COPY package.json pnpm-lock.yaml* /usr/src/app/

# Install only production dependencies using pnpm
RUN pnpm install --frozen-lockfile 

RUN pnpm fetch 

# Copy the rest of the application code
COPY . .
