无法使用 -OO 标志使用 astropy 运行代码

问：

我的代码按预期在 python 中运行，没有 python 标志，或者带有 -O 标志。它不适用于 -OO 标志。我的代码使用 astropy。Astropy 是一个 python 包，包含多个子包并使用了第三方代码层。

我已将代码简化为重现错误的最简单方法。minimalTest.py 内容为：

import astropy.coordinates
print('hello world')

以下 2 个命令按预期工作（每个命令都打印“hello world”）：

# python3 minimalTest.py
# python3 -O minimalTest.py

以下代码会生成错误：

# python3 -OO minimalTest.py

我认为这个问题可能与几年前关闭的 https://github.com/astropy/astropy/issues/10361 有关。此问题与 ply（astropy 使用的第三方代码）如何处理文档字符串有关。

我已经在带有 Python 3.9.10 的 Centos7 和带有 Python 3.11.2 的 Windows10 上重现了这个问题。
