Question

我查看了类似问题的一些答案，但似乎无法看到我的代码中出现错误的位置。当我尝试运行celery时发生错误：celery –A runLogProject worker –loglevel=INFO。我注释掉了与Celery相关的所有代码，它也给出了同样的错误。我也尝试重新安装芹菜。我不知道还有什么可以尝试的。这是追溯：

那个棘手的问题。问题在于你输入命令的方式：

错误：

celery –A runLogProject worker –loglevel=INFO

正确：

celery -A runLogProject worker -loglevel=INFO

几乎不可能发现差异。首先传递参数-A和-loglevel使用破折号（ascii代码：8211），但应使用连字符（ascii代码45）。

如果您使用的是OSX，可能会触发它，因为您按下ALT和连字符/减号键，或者您只是从使用奇怪的自动更正的博客中复制粘贴它。

UnicodeDecodeError：'ascii'编解码器无法解码位置0的字节0x96
