当导入umfpack MacOS Monterey M1芯片时模块未找到错误

Question

我使用安装了umfpack ，并尝试导入umfpack模块。

from scikits import umfpack

我遇到了以下错误：

Traceback (most recent call last):
  File "/Users/christianadib/pyfrbus_package/venv/lib/python3.9/site-packages/scikits/umfpack/_umfpack.py", line 18, in swig_import_helper
    fp, pathname, description = imp.find_module('__umfpack', [dirname(__file__)])
  File "/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/imp.py", line 296, in find_module
    raise ImportError(_ERR_MSG.format(name), name=name)
ImportError: No module named '__umfpack'

During handling of the above exception, another exception occurred:

  File "<stdin>", line 1, in <module>
  File "/Users/christianadib/pyfrbus_package/venv/lib/python3.9/site-packages/scikits/umfpack/__init__.py", line 12, in <module>

克里斯蒂安，这可不容易

1. pypi umfpack说:首先构建一个本地SuiteSparse UMFPACK
2. 构建SuiteSparse库需要一些Makefiles的知识 在macos otool / install_name_tool上
3. 在pip install之前，您需要一个合适的~/..numpy site.cfg。 补充说：setup.py是旧的，混乱的；我有一个简单的，它只工作一次，请告诉我。

您也可以尝试conda install scikit-umfpack而不是pip，但是混合不同的包管理器会带来麻烦；如果是这样的话，请将pip和conda包树分开。
