[Python]If this call came from a
在WIN PC中使用python(笔者python版本为3.10.7)处理抖音弹幕信息时,报错如下:
_descriptor.FieldDescriptor(File "C:\Users\xxx\AppData\Local\Programs\Python\Python310\lib\site-packages\google\protobuf\descriptor.py", line 560, in __new___message.Message._CheckCalledFromGeneratedFile()
TypeError: Descriptors cannot not be created directly.
If this call came from a _pb2.py file, your generated code is out of date and must be regenerated with protoc >= 3.19.0.
If you cannot immediately regenerate your protos, some other possible workarounds are:1. Downgrade the protobuf package to 3.20.x or lower.2. Set PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION=python (but this will use pure-Python parsing and will be much slower).More information:
经分析,代码中确实使用了python的protobuf库,根据提示可知需要降低protobuf的版本。
解决方法
在cmd中使用pip命令:pip3 show protobuf
(也可以用pip show protobuf
,或者使用pip list
or pip3 list
查看当前安装的所有库,里面有protobuf库的信息)。可以获悉,当前安装的版本是4.21.7。
将protobuf 4.21.7版本降级到3.20.x,即可解决问题。使用如下命令:
pip3 install --upgrade protobuf==3.20.1
补充说明:pip3是python3.x的命令,python3.x依旧兼容之前版本的pip指令。
