构建期间发生错误：命令 setuptools 失败

Question

我正在尝试在 AWS 上部署一个应用程序，但遇到了这个错误并且找不到如何让它工作。

错误：

构建期间发生错误：命令 setuptools 失败

01_packages.config

packages:
  yum:
    git: []
    postgresql-devel: []
    libjpeg-turbo-devel: []

commands:
    setuptools:
      command: /opt/python/run/venv/bin/pip install setuptools --upgrade

我猜 AWS 最近发生了变化，因为这在我之前的部署中有效。

我也不得不改变

postgresql93-devel: []

到

postgresql-devel: []

因为它之前给出了以下错误：

Yum 没有可安装的 postgresql93-devel

db-migrate.congi

  01_migrate:
    command: "django-admin.py migrate --noinput"

Answer 1

这会失败，因为文件 /opt/python/run/venv/bin/pip不存在。至少在 Amazon Linux 2 (python env) 上不是这样。

要解决这个问题，您可以使用

commands:
    setuptools:
      command: pip install setuptools --upgrade

为了检查它是否有效，我在测试 EB 环境 (64bit Amazon Linux 2 v3.0.1 running Python 3.7) 上验证：

此处概述了从 Amazon Linux 1 到 2 的一般迁移步骤：

• Migrating your Elastic Beanstalk Linux application to Amazon Linux 2
