python - 使用 Django、npm 和 gulp 创建 Docker 容器

Question

我更改了本地开发人员。到 docker 。我使用 Django 框架。对于前端，我使用 gulp build 命令来“创建”我的文件。现在我尝试了很多，查看了 Cookiecutter 和 Saleor 项目，但在安装 npm 时仍然遇到问题，我可以在我的 Docker 容器中调用 gulp 构建命令。

我已经尝试添加:

RUN curl -sL https://deb.nodesource.com/setup_10.x | bash -
RUN apt-get update && apt-get install -y \
    nodejs \

COPY ./package.json /app/
RUN npm install

虽然安装了 npm，但我仍然无法在我的容器中运行命令 gulp build。它只是说 gulp 是一个未知命令。所以看起来 npm 没有在我的 package.json 文件中安装定义的包。这里有人已经解决了这个问题并可以给我一些提示吗？

Dockerfile

# Pull base image
FROM python:3.7

# Define environment variable
ENV PYTHONUNBUFFERED 1

RUN apt-get update && apt-get install -y \
    # Language dependencies
    gettext \
    # In addition, when you clean up the apt cache by removing /var/lib/apt/lists
    # it reduces the image size, since the apt cache is not stored in a layer.
    && rm -rf /var/lib/apt/lists/*

# Set the working directory to /app
WORKDIR /app

# Copy the current directory contents into the container at /app
COPY . /app

# Install Python dependencies
RUN pip install pipenv
RUN pipenv install --system --deploy --dev

docker-compose.py

version: '3'

    services:
      web:
          build:
            context: .
            dockerfile: ./compose/local/django/Dockerfile
          env_file: .env
          volumes:
            - .:/app
          ports:
            - "8000:8000"
          depends_on:
            - db
          entrypoint: ./compose/local/django/entrypoint.sh
          container_name: myproject

      db:
        image: postgres
        ports:
          - "5432:5432"
        environment:
          # Password will be required if connecting from a different host
          - POSTGRES_PASSWORD=password

您确定在正确的目录中调用了 npm install 吗？您将 package.json 复制到 /app 但从未知文件夹运行 npm install。你可以试试:

COPY ./package.json /app/
RUN cd /app/ && npm install

但我认为无论如何你都想全局安装 gulp，所以你可以跳过 package.json 并只使用:

RUN npm install -g gulp-cli

这样无论调用 gulp 都应该在 PATH 中，而不仅仅是那个特定的目录。

另外，如果你想获得一个已经安装了 Python 3.7 和 Node.js 10 的 Docker 镜像，你可以使用 combos/python_node:3.7_10 .这是rebuilt daily包含两个图像的最新版本。
