在Python 2.7下安装Brightway2时出现UnicodeEncodeError

Question

Anaconda Python2.7

Ubuntu16.04 LTS

I have UnicodeEncodeError when installing Brightway2 by:

pip install brightway2

The UnicodeEncondeError:

UnicodeEncodeError: 'ascii' codec can't encode character u'\xfc' in position 50: ordinal not in range(128)

Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-ikaXlZ/bw2calc/

It only happens under Python2.7. When I switch to Python3.5 the error disappears and brightway2 works fine.

I have installed ftfy and eight to translate code between Python2.7 and Python3.

This is a bug in setuptools . In the meantime, I have released a new version of bw2calc that should fix this problem .
