Pandas失败，dateutil/tz.py第78行“self.\u name”，语法无效

Question

我有一个非常简单的Prophet脚本，我正在RHEL6.6圣地亚哥系统上运行。当我运行它时，我得到了这个回溯

Traceback (most recent call last):
  File "working_v1_runSplunkProphet.py", line 7, in <module>
    import pandas as pd
  File "/home/scadmin/prophet/lib/python3.6/site-packages/pandas/__init__.py", line 30, in <module>

SyntaxError: invalid syntax

我使用的是venv/lib/python3.6.site-packages/pip（python3.6）中的python3.6（3.6.8）和pip21.0.1。我也在虚拟环境（相同的版本）之外尝试过这个，并得到了相同的回溯。我正在使用pandas 1.1.15和dateutil 2.8.1

我已经按照Pandas import issues的建议尝试了以下操作

pip uninstall python-dateutil
pip install python-dateutil --upgrade

不久前我就遇到了这个问题，并且能够解决它，但我记不起是什么解决方案，或者似乎找不到上次有效的解决方案

非常感谢您提供的任何帮助
