python - 如何降级protobuf

Question

我偶然在我的 ubuntu vps 上更新了 protobuf。现在一些非常重要的 python 脚本不再工作了。速度其实并不重要。我有两个解决方案:

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If this call came from a _pb2.py file, your generated code is out of date and must be regenerated with protoc 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).

降级 protobuf 包，不确定是不是这样

或设置 PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION=python - 但我在哪里设置这个。在 python 脚本中？

Answer 1

使用 pip 降级 protobuf

pip install protobuf==3.20.*

这类似于 TypeError: Descriptors cannot not be created directly
