芹菜拋出的UnicodeDecodeError時嘗試啓動

Question

我想運行例如，從官方教程代碼（tasks.py）：

from celery import Celery 
app = Celery('tasks', broker='amqp://guest@localhost//') 
@app.task 
def add(x, y): return x + y 

我用命令「芹菜-A任務工人--loglevel =信息」，如圖教程。 但是，當我執行這個命令python拋出的UnicodeDecodeError：

C:\kaznmu\virtualenvs\example\Scripts>celery -A tasks worker --loglevel=info

• 我試着重新安裝所有的Python庫，並使用不同的版本，但是這並沒有幫助。我如何運行芹菜？
• 我使用的Windows7和Python2.7
• 官方教程這裏http://docs.celeryproject.org/en/master/getting-started/first-steps-with-celery.html#first-steps

問題是計算機名俄語字符。通過重命名PC名稱解決。
