UnicodeDecodeError for obonet0.2.5

[ItWasLGS]

Hi,I am a new one to obonet and recently have an strict environment restriction for obonet0.2.5 and python3.7.9
As I try to install it I meet an UnicodeDecodeError such as shown belows:

(test2) C:\Users\dell>pip install obonet==0.2.5
Collecting obonet==0.2.5
  Using cached obonet-0.2.5.tar.gz (5.5 kB)
  Preparing metadata (setup.py) ... error

      UnicodeDecodeError: 'gbk' codec can't decode byte 0xa5 in position 935: illegal multibyte sequence

  note: This error originates from a subprocess, and is likely not a problem with pip.

the environment test2 shown above is a brand new environment with python3.7.9 construted by anaconda,I've read the closed issues but it didn't make it with any pip updates,please help me with this embarrasing bug(O-r-z),thank you!

Here is the source code where your error is occurring in v0.2.5:

obonet/setup.py

Lines 17 to 18 in 07365ec

	with readme_path.open() as read_file:
	long_description = read_file.read()

Notice how our setup.py didn't specify an encoding. It should have specified encoding = 'utf-8', such that when a user system defaults to a different encoding, it would still use utf-8. You can try to run the following:

PYTHONIOENCODING=UTF-8 pip install obonet==0.2.5

That might work. Otherwise, can you upgrade to latest obonet version 0.3.0, which shouldn't have this problem.

Thanks for your quick reply,I think I might get where the error is from,but after I run your code listed above something else goes wrong,as shown below:

(test2) C:\Users\dell>PYTHONIOENCODING=UTF-8 pip install obonet==0.2.5
'PYTHONIOENCODING' is not recognized as an internal or external command,
operable program or batch file.

It frustrated me and I come back to look for your help..
But in the other way,considering it's an encoding error,I downloaded your obonet ver0.2.5,changed line 17 in setup.py into:

with readme_path.open(encoding='utf-8') as read_file

then I successfully in pip install progress,but I wonder would this change have an bad effect on obonet(or even ruin your code) since it's too simple while nobody has tried it?

The code should work in a bash (or other unix-like) shell, but does not work on the Windows command prompt.

That is fine. Personally I think upgrading to the latest obonet==0.3.0 is a better solution, since it doesn't require manually editing a file everytime.

Glad you were able to find a method that works.
