python3连接etcd3 grpc报错解决方法

本例环境如下：

python版本: 3.7

etcd3版本: 0.12.0

报错信息：

File "/tools/apps/venv/lib/python3.7/site-packages/etcd3/client.py", line 48, in handler _translate_exception(exc) File "/tools/apps/venv/lib/python3.7/site-packages/etcd3/client.py", line 46, in handler return f(*args, **kwargs) File "/tools/apps/venv/lib/python3.7/site-packages/etcd3/client.py", line 424, in put metadata=self.metadata File "/tools/apps/venv/lib/python3.7/site-packages/grpc/_channel.py", line 946, in __call__ return _end_unary_response_blocking(state, call, False, None) File "/tools/apps/venv/lib/python3.7/site-packages/grpc/_channel.py", line 849, in _end_unary_response_blocking raise _InactiveRpcError(state)grpc._channel._InactiveRpcError: <_InactiveRpcError of RPC that terminated with: status = StatusCode.UNAUTHENTICATED details = "Established channel does not have a sufficient security level to transfer call credential." debug_error_string = "{"created":"@1650335047.885697270","description":"Error received from peer 172.0.0.1:8030","file":"src/core/lib/surface/call.cc","file_line":906,"grpc_message":"Established channel does not have a sufficient security level to transfer call credential.","grpc_status":16}"

本例连接异常是因为grpcio版本太高，grpcio==1.45.0

降级后解决

pip uninstall grpcio

pip install grpcio==1.19.0
