所以我有一个前端Nuxt.js和一个FastAPI都在一个Docker容器中。两个服务器运行命令都可以在没有Docker的情况下工作。
Docker的文件系统如下所示：

├── Dockerfile -- FastAPI docker file
├── docker-compose.yml 
└── front
    ├── Dockerfile -- Nuxt docker file

运行docker-compose up时，FastAPI服务器正常工作，但nuxt抛出此错误

Dockerfile看起来像这样：

FROM node:12.16.3-alpine3.9

# Create destination
RUN mkdir -p /front
WORKDIR /front

#compile app
COPY package.json .
COPY package-lock.json .

RUN npm install

COPY . .
RUN npm build

EXPOSE 3000

ENV NUXT_HOST=0.0.0.0
ENV NUXT_PORT=3000

CMD [ "npm","run", "start" ]

.dockerignore看起来像这样：

node_modules
npm-debug*
.nuxt
dist
tests
.output

docker-compose.yml看起来像这样：

version: '2'
services:
    app:
        build: .
        container_name: FastAPI
        command: uvicorn app.main:app --host 0.0.0.0
        ports:
            - 8000:8000
    front:
        build: ./front
        container_name: Nuxt-frontend
        command: npm start
        ports:
            - 3000:3000

注意：我已经尝试过将"type": "module"添加到package.json中
