Django、GDAL 和 CircleCI 2

Question

我有一个配置了 GeoDjango 的 Django 应用程序在 CircleCI 2.0 构建中失败并出现以下错误:

django.core.exceptions.ImproperlyConfigured: Could not find the GDAL library. Is GDAL installed? If it is, try setting GDAL_LIBRARY_PATH in your settings.

但是，当我从 settings.py 中的 DJANGO_APPS 中删除 'django.contrib.gis' 时，构建会成功运行。

除了 postgres 和 GDAL docker 镜像之外，在 CircleCI 中配置 GDAL 是否还有其他步骤？我(可能是错误的)假设在安装 docker 镜像后会找到 GDAL。下面是我的 config.yml:

version: 2
jobs:
  build:
    docker:
      - image: circleci/python:3.6.3

      - image: circleci/postgres:10.1-postgis
        environment:
        - POSTGRES_USER=ubuntu
        - POSTGRES_DB=myapp_test

      - image: geodata/gdal

    working_directory: ~/repo

    steps:
      - checkout

      # Download and cache dependencies
      - restore_cache:
          keys:
          - v1-dependencies-{{ checksum "requirements.txt" }}
          # fallback to using the latest cache if no exact match is found
          - v1-dependencies-

      - run:
          name: install dependencies
          command: |
            python3 -m venv venv
            . venv/bin/activate
            pip install -r requirements.txt
      - save_cache:
          paths:
            - ./venv
          key: v1-dependencies-{{ checksum "requirements.txt" }}

      - run:
          name: run tests
          command: |
            . venv/bin/activate
            python manage.py test
          environment:
            DATABASE_URL: "postgres://ubuntu@localhost:5432/myapp_test"

      - store_artifacts:
          path: test-reports
          destination: test-reports

Answer 1

我通过添加以下内容来修复它:

apt-get update && apt-get install -y \
gdal-bin python-gdal python3-gdal

就在你运行pip install的地方:

  - run:
      name: install dependencies
      command: |
        python3 -m venv venv
        . venv/bin/activate
        pip install -r requirements.txt
        apt-get update && apt-get install -y \
        gdal-bin python-gdal python3-gdal
