If this problem is reproducible for you, can you give me the output of

conda create -n test qt -vvv

It'll be a lot of output. Feel free to email it to me if you want. kale@franz.io

I have the similar error too.

I found the reason. It is because OS message is not encoded in utf-8 (in my case, CP949)

On installation, subprocess_call function is called:

return Response(ensure_text_type(stdout), ensure_text_type(stderr), int(rc))

Inside, this function calls ensure_text_type to validate standard output:

def ensure_text_type(value):

ensure_text_type raises a Unicode error because subprocess' standard output includes not-encoded-in-utf-8 string.

But, I have no idea why there was no problem when I installed qt in root environment.

Temporarily, I fixed this problem by modifying ensure_text_type like this:

import chardet

def ensure_text_type(value):
    if isinstance(value, text_type):
        encoding = 'utf-8'
    else:
        encoding = chardet.detect(value).get('encoding') or 'utf-8'
    return value.decode(encoding) if hasattr(value, 'decode') else value

Thank you very much! However, I'm a newcomer here, could you tell me what should I do to solve this problem, by the way? Should I just activate the user environment and run your program or download your program file into some specific directory?
