**The latest version of the CDSAPI now requires Python 3.8 or above.**

I have been working on a system that only supports Python 3.6. Until September 28th, the application was functioning correctly, but since then, I have encountered issues with downloading ECMWF ERA5 data. Is there a solution to this problem?

Is there any alternative method to retrieve the data while still using Python 3.6?

为啥不安装两个版本的python呢？一个用来下数据，一个用来干别的

I am seeing the same issue - would like to see a response to this from ECMWF.
