Anaconda添加channels后出现unexpected urllib3 DEBUG logging from conda-build

1.问题描述

anaconda更新之后添加channels后出现bug:

(base) ~/zlib-feedstock % conda build recipe 2>&1 | tee out
...

2. 解决方法

出现的原因是因为conda-build-3.26.0版本问题，修改了一些内容。

解决：

方法①：降低conda-build的版本

conda install conda-build=3.25.0

方法②：升级conda-build的版本（目前最新版本是3.26.1）

conda update conda-build 

方法③：移出conda-build组件，不影响正常使用

conda remove conda-build
