Question

在具有python 3.6.8的Ubuntu 18.04上，尝试安装气流。当我运行airflow initdb命令时，抛出以下错误

ModuleNotFoundError: No module named 'werkzeug.wrappers.json'; 'werkzeug.wrappers' is not a package

尝试过pip3 install --upgrade Flask

Answer 1

“ pip3 install werkzeug == 0.15.4”解决了我的问题。似乎烧瓶引用了错误版本的werkzeug。

Answer 2

运行pip3 install -U Flask==1.0.4解决了该问题。我猜Flask 1.1.0出现了一些问题，影响了气流。

Apache Airflow：气流initdb抛出ModuleNotFoundError：没有名为“ werkzeug.wrappers.json”的模块； 'werkzeug.wrappers'不是软件包错误
