django - 通过无服务器运行 Django 时出现 Psycopg2 错误

问题描述

文件“/var/task/django/db/backends/postgresql/base.py”，第 29 行，在 raise ImproperlyConfigured("Error loading psycopg2 module: %s" % e) django.core.exceptions.ImproperlyConfigured: Error loading psycopg2模块：libpq.so.5：无法打开共享对象文件：没有这样的文件或目录

通过无服务器部署 Django 应用程序后，我收到以下错误。如果我通过我们的 Bitbucket 管道部署应用程序。

这是管道：

    - step: &Deploy-serverless
        caches:
          - node
        image: node:11.13.0-alpine
        name: Deploy Serverless
        script:
          # Initial Setup
          - apk add curl postgresql-dev gcc python3-dev musl-dev linux-headers libc-dev

          # Load our environment.
          ...

          - apk add python3
          - npm install -g serverless

          # Set Pipeline Variables
          ...

          # Configure Serverless
          - cp requirements.txt src/requirements.txt
          - printenv > src/.env
          - serverless config credentials --provider aws --key ${AWS_KEY} --secret ${AWS_SECRET}
          - cd src
          - sls plugin install -n serverless-python-requirements
          - sls plugin install -n serverless-wsgi
          - sls plugin install -n serverless-dotenv-plugin

这是无服务器文件：

service: serverless-django

plugins:
  - serverless-python-requirements
  - serverless-wsgi
  - serverless-dotenv-plugin

custom:
  wsgi:
    app: arc.wsgi.application
    packRequirements: false
  pythonRequirements:
    dockerFile: ./serverless-dockerfile
    dockerizePip: non-linux
    pythonBin: python3
    useDownloadCache: false
    useStaticCache: false

provider:
  name: aws
  runtime: python3.6
  stage: dev
  region: us-east-1
  iamRoleStatements:
    - Effect: "Allow"
      Action:
        - s3:GetObject
        - s3:PutObject
      Resource: "arn:aws:s3:::*"

functions:
  app:
    handler: wsgi.handler
    events:
      - http: ANY /
      - http: "ANY {proxy+}"
    timeout: 60

这是 Dockerfile：

FROM lambci/lambda:build-python3.7
RUN yum install -y postgresql-devel python-psycopg2 postgresql-libs

这是要求：

这是数据库设置：

# Database Defintions
DATABASES = {
    "default": {
        "ENGINE": "django.db.backends.postgresql_psycopg2",
        "HOST": load_env("PSQL_HOST", "127.0.0.1"),
        "NAME": load_env("PSQL_DATABASE", ""),
        "PASSWORD": load_env("PSQL_PASSWORD", ""),
        "USER": load_env("PSQL_USERNAME", ""),
        "PORT": load_env("PSQL_PORT", "5432"),
        "TEST": {
            "NAME": "arc_unittest",
        },
    },
}

我不知道到底是什么问题。想法？

文件“/var/task/django/db/backends/postgresql/base.py”，第 29 行，在 raise ImproperlyConfigured("Error loading psycopg2 module: %s" % e) django.core.exceptions.ImproperlyConfigured: Error loading psycopg2模块：没有名为“psycopg2._psycopg”的模块

在本地部署时，我收到了类似的错误。
