使用GRPC GET導入錯誤，未定義的符號：grpc_google_iam_credentials_create

Question

我用GRPC在Ubuntu中，當進口* _pb2.py它通過run_codegen.sh產生的，我得到了下面的導入錯誤：

raceback (most recent call last): 
File "q_db_op.py", line 2, in <module> 
import db_op_pb2 
    File "/data/server/grpc/db_op_pb2.py", line 331, in <module> 
from grpc.early_adopter import implementations 
    File "/usr/local/lib/python2.7/dist-packages/grpc/early_adopter/implementations.py", line 34, in <module> 
from grpc._adapter import fore as _fore 
    File "/usr/local/lib/python2.7/dist-packages/grpc/_adapter/fore.py", line 38, in <module> 
from grpc._adapter import _intermediary_low as _low 
    File "/usr/local/lib/python2.7/dist-packages/grpc/_adapter/_intermediary_low.py", line 57, in <module> 
from grpc._adapter import _low 
    File "/usr/local/lib/python2.7/dist-packages/grpc/_adapter/_low.py", line 31, in <module> 
from grpc._adapter import _c 
ImportError: /usr/local/lib/python2.7/dist-packages/grpc/_adapter/_c.so: undefined symbol: grpc_google_iam_credentials_create 

任何反饋將不勝感激。

這聽起來有點像你只安裝了gRPC Python並且還沒有在你的系統上安裝gRPC Core。如果是這種情況，解決您的問題的辦法是安裝gRPC核心（「sudo apt-get install libgrpc-dev」，請參閱installation instructions）。

另請注意，您apt安裝（0.11，0.12或更高版本）的gRPC Core版本與您pip安裝的grpcio PyPI軟件包的版本相同（0.11,0.12或稍後的某些事）。
