Airflow 无法导入名称'；运行initdb时出现不正确的SchemaTypeError

我正在与：

ubuntu 18.04.4 LTS
python 3.6.9

我安装aitflow时使用：

pip install apache-airflow

并尝试初始化数据库：

airflow initdb

并获取以下错误：

我如何修复它？

遇到了同样的故障

通过使用违禁品重新安装气流来修复，如官方文件中所述：

是。我收到以下错误：“ImportError:无法导入名称‘解析类型’”

AIRFLOW_VERSION=1.10.12
PYTHON_VERSION="$(python --version | cut -d " " -f 2 | cut -d "." -f 1-2)"
CONSTRAINT_URL="https://raw.githubusercontent.com/apache/airflow/constraints-${AIRFLOW_VERSION}/constraints-${PYTHON_VERSION}.txt"

# For example: 3.6
# https://raw.githubusercontent.com/apache/airflow/constraints1.10.12/constraints-3.6.txt

pip install "apache-airflow==${AIRFLOW_VERSION}" --constraint "${CONSTRAINT_URL}"
