问题描述：

使用 pip 已经更新 grpcio 至最新版，调用时还是报错  如下图：

Traceback (most recent call last):File "/Users/yu/anaconda3/envs/dify2/lib/python3.10/site-packages/flask/cli.py", line 245, in locate_app__import__(module_name)File "/Users/yu/Desktop/code/yuCode/pyCode/dify/api/app.py", line 8, in <module>import grpc.experimental.geventFile "/Users/yu/anaconda3/envs/dify2/lib/python3.10/site-packages/grpc/__init__.py", line 22, in <module>from grpc import _compressionFile "/Users/yu/anaconda3/envs/dify2/lib/python3.10/site-packages/grpc/_compression.py", line 20, in <module>from grpc._cython import cygrpc
ImportError: dlopen(/Users/yu/anaconda3/envs/dify2/lib/python3.10/site-packages/grpc/_cython/cygrpc.cpython-310-darwin.so, 2): no suitable image found.  Did find:/Users/yu/anaconda3/envs/dify2/lib/python3.10/site-packages/grpc/_cython/cygrpc.cpython-310-darwin.so: mach-o, but wrong architecture/Users/yu/anaconda3/envs/dify2/lib/python3.10/site-packages/grpc/_cython/cygrpc.cpython-

解决方案：

在 ~/.bash_profile 或者 ~/.zshrc 添加环境变量 

export GRPC_PYTHON_BUILD_SYSTEM_OPENSSL=1
export GRPC_PYTHON_BUILD_SYSTEM_ZLIB=1
export GRPC_PYTHON_LDFLAGS=" -framework CoreFoundation"

再次执行 成功运行

pip install grpcio --no-binary :all:
