                 Key: FLINK-12931
                 URL: https://issues.apache.org/jira/browse/FLINK-12931
             Project: Flink
          Issue Type: Bug
          Components: API / Python
    Affects Versions: 1.9.0
            Reporter: Bowen Li

             Fix For: 1.9.0


Hi guys,

I tried to run tests for flink-python with {{./dev/lint-python.sh}} by following README. But it reported it couldn't find flake8, error as

{code:java}
./dev/lint-python.sh: line 490: /.../flink/flink-python/dev/.conda/bin/flake8: No such file or directory
{code}

I've tried {{./dev/lint-python.sh -f}}, also didn't work.

I suspect the reason may be that I already have an anaconda3 installed and it conflicts with the miniconda installed by flink-python somehow. I'm not fully sure about that.

If that's the reason, I think we need to try to resolve the conflict because anaconda is a pretty common package that developers install and use. We shouldn't require devs to uninstall their existing conda environment in order to develop flink-python and run its tests. It's better if flink-python can have a well isolated environment on machines.
