Are there any pre-requirements to install this modules?

Hi @jiamingl98 , thanks for the report.

This is a rather weird error - it looks like when trying to read the README.md it encounters a byte representation that it is not able to decode. I've tried installing from pypi and that worked fine for me. Is it possible that the default unicode encoding on your machine is not UTF-8?

Would you mind trying the following:

• clone the git repository
• try reading the README file from python:

  python
  >>> open('README.md').read()

  I suspect that this will throw the same error (if not, I'm lost).

Can you then try:

>>> import io
>>> io.open('README.md', encoding='utf-8').read()

and see whether that works?

[ltalirz]

try to clone the branch https://github.com/ltalirz/lammps_interface/tree/fix-utf8 from my fork and install it from there using pip install -e .

I suspect this will have fixed the issue - let me know

[jiamingl98]

The issue has fixed. Thanks.

just tagged v0.2.2 should be out on pypi soon
