Dear all,
I'm trying to run OQ some days after the OS updating.
What I obtain is this error message:

OSError: Could not find lib c or load any of its variants [].

Anyone has the same problem? Any suggestion?

Xcode seems to be rightly updated, and the same for the command line tool.

Thank you in advance for the kindness,

bye,

Marco

I haven’t yet tested Big Sur. You might want to google a bit to find a solution e.g.

This is a know issue: https://github.com/gem/oq-engine/issues/6277
The solution is to upgrade shapely.

Thank you Michele and Marco,

I upgraded shapely, but the result is the same:

OSError: Could not find lib c or load any of its variants [].

So I tried to update all the packages:
pip freeze --local | grep -v '^\e' | cut -d = -f 1 | xargs -n1 pip install -U
But still it doesn’t work.

I’ll search again in the net, but I’m open to any other idea you can give me,

Thank you in advance,

Bye,

Marco.

As we said in another thread, we have an universal installer now. For us it works on Big Sur too. Instructions:

$ python3.7 install.py user

Since this is very new, please let us know if it works for you. Thanks,
