Linux conda install cannot find libcasm

[Dongsheng-Wen]

Hi, I recently tried to install CASM on my linux machines, using the installation guide on conda environment. The ccasm was successfully install but when I typed casm, it looks like the api didn't find the path of the libcasm. Here is the traceback error:

' libcasm

  STDOUT:


  STDERR:
/usr/bin/grep: libcasm: No such file or directory

What I think it is related to the api.py in which the 'libcasm' wasn't found from the line:

libcasm_path = sh.grep(sh.ldd(casm_path),
                                               'libcasm').split()[2]

Any ideas of a quick fix?

Best, Dongsheng

• The latest version of sh seems to have some issues with casm-python
• Installing an older version like pip3 install sh=1.14.2 --user should fix the issue.
