Installation 气流2导入例外

我卸载了airflow 1.10.12，并使用python 3.6.9安装了airflow 2。在没有自定义DAG的情况下启动Web服务器时，会收到警告：

这可以被忽略吗？原因是什么

问候

奥利

这些是缺失模块的警告。 当1.0>2.0时，气流改变了结构

如果不打算使用谷歌云插件，您可以忽略这些，或者安装其他模块：

pip install --upgrade apache-airflow-providers-google

安装上面的模块后，您可能需要更多的模块，如mysql、paramiko和ssh。 您可以通过以下方式安装它们：

pip install --upgrade paramiko
pip install --upgrade apache-airflow-providers-ssh
pip install --upgrade apache-airflow-providers-mysql
