最近我想在 Mac 上尝试 flow-project，在安装了所有要求并尝试运行 python examples/sumo/sugiyama.py 之后，我收到了如下所述的错误。你能帮我解决吗？

Traceback (most recent call last):

    from flow.core.experiment import Experiment

    from flow.core.util import emission_to_csv

    from lxml import etree

我遇到了同样的问题并卸载了conda版本lxml并再次使用pip.

conda uninstall lxml
pip install lxml
