Question

我想从官方教程中运行示例代码（tasks.py）：

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

我使用了命令“celery -A task worker --loglevel = info”，如教程中所示。但是，当我执行此命令时，python会抛出UnicodeDecodeError：

我尝试重新安装所有python库并使用不同的版本，但这没有帮助。我该怎么办芹菜？
我使用Windows7和Python2.7
这里的官方教程http://docs.celeryproject.org/en/master/getting-started/first-steps-with-celery.html#first-steps

Answer 1

问题是电脑名称中的俄文字符。通过重命名pc名解决。

尝试启动时，芹菜会抛出unicodedecodeerror
