AttributeError: '_io.TextIOWrapper' object has no attribute 'decode'
时间: 2023-09-26 19:14:23 浏览: 80
This error occurs when you try to call the `decode()` method on an object of type `_io.TextIOWrapper`.
The `decode()` method is used to convert a sequence of bytes into a string, but `_io.TextIOWrapper` objects are already text-based, so they don't need to be decoded.
To fix this error, you should remove the `decode()` method call from your code. If you're trying to read binary data from a file, you should open the file in binary mode using the `'rb'` flag, like this:
```
with open('myfile.bin', 'rb') as f:
data = f.read()
```
Then you can convert the binary data to a string using the `decode()` method:
```
text = data.decode('utf-8')
```

attributeerror: '_io.textiowrapper' object has no attribute 'decode'
这是一个错误提示,意思是“属性错误:'_io.textiowrapper'对象没有'decode'属性”。这通常是因为在尝试对一个文本I/O对象进行解码操作时出现了问题。可能是因为该对象已经是一个已经解码的字符串,或者是因为该对象不支持解码操作。
为什么报错说AttributeError: '_io.TextIOWrapper' object has no attribute 'decode'
这个错误通常是因为在Python 3.x版本中,已经没有decode()方法了,因为在Python 3.x版本中,所有的字符串都是Unicode编码,所以不需要解码。如果你需要从文件或网络中读取二进制数据,你可以使用bytes类型代替str类型。如果你需要将bytes类型转换为str类型,可以使用bytes对象的decode()方法。可能是在使用Python 2.x版本的代码在Python 3.x版本中运行时出现的错误。
