Question

我正在尝试安装索引器，但出现以下错误。谁能帮我这个忙吗？

Python3不允许像Python2一样用逗号分隔错误消息。您应该使用额外的print（）语句。

except OSError as ex:
    print(ex.args)

[the docs说：

try: 
     raise Exception('spam', 'eggs')  
except Exception as inst:
     print(type(inst))    # the exception instance 
     print(inst.args)     # arguments stored in .args

这就是except OSError, ex:给出错误的原因。
