Describe the bug
After installing QuakeMigrate, accessing python to execute “import quakemigrate”, prompting the problem.

To Reproduce
import quakemigrate
Traceback (most recent call last):
File "/Users/guanlingpeng/QuakeMigrate/quakemigrate/core/libnames.py", line 39, in _load_cdll
cdll = ctypes.CDLL(str(lib))
File "/Users/guanlingpeng/anaconda3/envs/quakemigrate/lib/python3.7/ctypes/init.py", line 364, in init
self._handle = _dlopen(self._name, mode)
OSError: dlopen(/Users/guanlingpeng/QuakeMigrate/quakemigrate/core/src/qmlib.cpython-37m-darwin.so, 0x0006): tried: '/Users/guanlingpeng/QuakeMigrate/quakemigrate/core/src/qmlib.cpython-37m-darwin.so' (no such file), '/usr/local/lib/qmlib.cpython-37m-darwin.so' (no such file), '/usr/lib/qmlib.cpython-37m-darwin.so' (no such file)

During handling of the above exception, another exception occurred:

ImportError: Could not load extension library 'qmlib'.

dlopen(/Users/guanlingpeng/QuakeMigrate/quakemigrate/core/src/qmlib.cpython-37m-darwin.so, 0x0006): tried: '/Users/guanlingpeng/QuakeMigrate/quakemigrate/core/src/qmlib.cpython-37m-darwin.so' (no such file), '/usr/local/lib/qmlib.cpython-37m-darwin.so' (no such file), '/usr/lib/qmlib.cpython-37m-darwin.so' (no such file)

If you have chosen to install from a clone of the github repository, please ensure you have run 'python setup.py install', which will compile and install the C library. See the installation documentation for more details.

Expected behavior
Miss the file 'qmlib.cpython-37m-darwin.so'

Desktop (please complete the following information):

Operating System: macOS Monterey
Python version: Python=3.7
QuakeMigrate version: Version=1.0.0

In addition, the path of running 'import quakemigrate'
In the downloaded package ‘QuakeMigrate’

from quakemigrate.

Great, thanks - can you run the following in terminal and paste the full outputs here:

1. Test if the compiled shared object is installed in the conda environment

ls /Users/guanlingpeng/anaconda3/envs/quakemigrate/lib/python3.7/site-packages/quakemigrate/core/src

If there is a file that looks like qmlib.cpython-37m-darwin.so, then the issue is related to #129 - if you change directory to anywhere but /Users/guanlingpeng/QuakeMigrate (such as /Users/guanlingpeng/QuakeMigrate/examples) and try again. Or you could switch to the tests directory and try running the tests.

If the file is not there, then it suggests an issue when the core routines are being compiled. We have encountered issues with Mac compilers in the past, so it is not unheard of. If this is the case, you can rerun pip install . in the base QuakeMigrate directory and share the entire output here.

2. Check compiler version you have installed and where. In terminal, with your environment activated to be sure, enter:

gcc -v
which gcc

We should be able to troubleshoot any issues with this information.

It is OK when install pyqt.

@TomWinder Yes, this issue is resolved, after changing directory and installing pyqt 5.9.2.
Thank you very much!

Oh my god, I still don't know how to solve it！！

from quakemigrate.

Can you provide the information that Tom requested above? In particular, the operating system and where in your path you are running the import quakemigrate command.

Thank you.

Thanks, hemmelig.
The file is there, I then change the path to */QuakeMigrate/examples, and try again. Prompting:

Problem maybe the version of matplotlib. My version is matplotlib=3.2.2. So, I try numerous versions, problem remains and varies.

@glPeng-seis Please can you confirm that this is issue is now resolved, after changing directory and sorting out pyqt? Cheers.
