hankehly opened a new issue #13149: URL: https://github.com/apache/airflow/issues/13149
**Apache Airflow version**: 2.0 **Environment**: - **Cloud provider or hardware configuration**: Local development environment using docker - **OS** (e.g. from /etc/os-release): macOS Catalina (10.15.7) - **Kernel** (e.g. `uname -a`): Darwin - **Install tools**: [poetry](https://python-poetry.org/) - **Others**: docker 20.10.0, postgres, Python 3.7.9 **What happened**: A fresh installation of airflow 2.0 seems to be failing on `airflow db init` with what looks like a 3rd-party library exception (see traceback below). I searched for related issues on github/google; but didn't find anything useful. **What you expected to happen**: Given I couldn't find any useful information online, this makes me think the problem is my environment. I will continue to look at it, but in the meantime I'd like to put this out there in case anyone else has had a similar issue. **How to reproduce it**: #### 1. Install [poetry](https://github.com/python-poetry/poetry) package manager ``` curl -sSL https://raw.githubusercontent.com/python-poetry/poetry/master/get-poetry.py | python ``` #### 2. Create a `docker-compose.yml` file inside a new directory ```yaml version: "3.9" services: db: environment: POSTGRES_USER: airflow POSTGRES_PASSWORD: airflow POSTGRES_DB: airflow POSTGRES_PORT: 5432 image: postgres ports: - 5432:5432 ``` #### 3. Create a `pyproject.toml` file inside the same directory as (2) ```toml [tool.poetry] name = "airflow-2-docker-example" version = "0.1.0" description = "" authors = ["name <n...@example.com>"] [tool.poetry.dependencies] python = "^3.7" apache-airflow = "^2.0.0" psycopg2-binary = "^2.8.6" [tool.poetry.dev-dependencies] [build-system] requires = ["poetry-core>=1.0.0"] build-backend = "poetry.core.masonry.api" ``` #### 4. Install python packages and bring up the database ```sh poetry install docker-compose up -d ``` #### 5. Initialize airflow database ```sh AIRFLOW__CORE__SQL_ALCHEMY_CONN=postgresql+psycopg2://airflow:airflow@localhost:5432/airflow poetry run airflow db init ``` **Anything else we need to know**: <!-- How often does this problem occur? Once? Every time etc? Any relevant logs to include?
