UnicodeDecodeError: 'ascii' 编码无法解码位置0的字节0x96

Question

我看了很多类似问题的回答，但还是找不到我代码出错的地方。错误发生在我尝试运行 celery 的时候，命令是：celery –A runLogProject worker –loglevel=INFO。我把所有和 Celery 有关的代码都注释掉了，但还是出现同样的错误。我也试着重新安装了 Celery，但还是不行。我不知道该尝试什么其他方法。以下是错误的详细信息：

Answer 1

这个问题有点棘手。问题出在你输入命令的方式上：

错误的：

celery –A runLogProject worker –loglevel=INFO

正确的：

celery -A runLogProject worker -loglevel=INFO

这两者之间几乎看不出区别。第一个命令中，参数 -A 和 -loglevel 使用的是长横线（ascii 码：8211），而应该使用的是短横线（ascii 码：45）。

如果你在使用 OSX 系统，这可能是因为你在按下短横线键的时候同时按了 ALT 键，或者你是从某个博客上复制粘贴过来的，而那个博客用了奇怪的自动纠正功能。
