我正在try 在python3.9.6和MacOS Sonoma 14.3.1下安装pyregion(一个与天文数据分析有关的包).
我try 过各种方法，但总是遇到新的障碍. 在标准方法之后: pip3 install pyregion 它失败并出现错误消息 "Failed building wheel for pyregion". 在try 了在stackoverflow上找到的许多其他建议之后，包括升级numpy，升级pip3本身， python3 -m pip install pyregion
我现在try 直接安装这些文件，这些文件可以在以下位置找到: https://pypi.org/project/pyregion/#files个
run 的第一个障碍
python3 setup.py install个
是:
Traceback (most recent call last):
File "/Users/claudiopedrazzi/Downloads/pyregion-2.2.0/setup.py", line 5, in <module>
from Cython.Build import cythonize
ModuleNotFoundError: No module named 'Cython'*
然后我还安装了Cython
pip3 install --upgrade cython
它成功地为我安装了cython—3.0.9. 再次try 运行www.example.com，我得到一个很长的错误消息，结尾是:

我真的需要一步一步的指导.我的环境是最新的，我不明白为什么这个特殊的包会出现这些问题，而其他的包，如astropy和matplotlib工作得很好.
