Error while installing

See original GitHub issue

The readme says that the installation specifically requires UMLS MRCONSO.RRF and MRSTY.RRF. I put these files separately in a new directory and provide it as an argument <umls_installation_path>. When I do python -m quickumls.install <umls_installation_path> <destination_path>, I get the following error: Traceback (most recent call last): File "/users/PAS1440/deyosu78/.conda/envs/chemprop/lib/python3.6/runpy.py", line 183, in _run_module_as_main mod_name, mod_spec, code = _get_module_details(mod_name, _Error) File "/users/PAS1440/deyosu78/.conda/envs/chemprop/lib/python3.6/runpy.py", line 109, in _get_module_details __import__(pkg_name) File "/users/PAS1440/deyosu78/.conda/envs/chemprop/lib/python3.6/site-packages/quickumls/__init__.py", line 1, in <module> from .core import QuickUMLS File "/users/PAS1440/deyosu78/.conda/envs/chemprop/lib/python3.6/site-packages/quickumls/core.py", line 17, in <module> from . import toolbox File "/users/PAS1440/deyosu78/.conda/envs/chemprop/lib/python3.6/site-packages/quickumls/toolbox.py", line 23, in <module> from quickumls_simstring import simstring File "/users/PAS1440/deyosu78/.conda/envs/chemprop/lib/python3.6/site-packages/quickumls_simstring/simstring.py", line 28, in <module> _simstring = swig_import_helper() File "/users/PAS1440/deyosu78/.conda/envs/chemprop/lib/python3.6/site-packages/quickumls_simstring/simstring.py", line 24, in swig_import_helper _mod = imp.load_module('_simstring', fp, pathname, description) File "/users/PAS1440/deyosu78/.conda/envs/chemprop/lib/python3.6/imp.py", line 243, in load_module return load_dynamic(name, filename, file) File "/users/PAS1440/deyosu78/.conda/envs/chemprop/lib/python3.6/imp.py", line 343, in load_dynamic return _load(spec) ImportError: /users/PAS1440/deyosu78/.conda/envs/chemprop/lib/python3.6/site-packages/quickumls_simstring/_simstring.so: undefined symbol: libiconv I don’t know how to resolve this? Anyone faced this issue before? Any solution?
