Unable to generate client code using proto 3.0 buffer in gRPC
问题
我正在尝试在gRPC中生成客户端和服务器代码。我已经从GitHub安装了grpc目录，并尝试生成C++代码。我安装了proto编译器3.0.0。
当我执行protoc时，我得到以下错误：
$ protoc -I ../../protos/ --grpc_out=. --plugin=protoc-gen-grpc=grpc_cpp_plugin ../../protos/helloworld.proto
grpc_cpp_plugin: program not found or is not executable
--grpc_out: protoc-gen-grpc: Plugin failed with status code 1.
有任何想法为什么我无法生成客户端/服务器代码吗？

I am trying to generate client and server code in gRPC. I have installed grpc directory from github and trying to generate C++ code. I installed proto compiler 3.0.0.
When I am executing protoc i am getting below error
$ protoc -I ../../protos/ --grpc_out=. --plugin=protoc-gen-grpc=grpc_cpp_plugin ../../protos/helloworld.proto
grpc_cpp_plugin: program not found or is not executable
--grpc_out: protoc-gen-grpc: Plugin failed with status code 1.
Any idea why I am not able to generate client/server code

请检查/usr/local/bin目录。它应该与其他语言的插件一起存在。
/usr/local/bin > ll total 71144 -rwxr-xr-x 1 root root 12721867 Oct 23 10:44 grpc_cpp_plugin* -rwxr-xr-x 1 root root 14509678 Oct 23 10:44 grpc_csharp_plugin* -rwxr-xr-x 1 root root 13339870 Oct 23 10:44 grpc_objective_c_plugin* -rwxr-xr-x 1 root root 12569518 Oct 23 10:44 grpc_python_plugin* -rwxr-xr-x 1 root root 12393363 Oct 23 10:44 grpc_ruby_plugin*
如果你有其他插件但没有cpp插件，可能在安装时忽略了某些步骤。
如果存在，请尝试在编译时指定完整路径（例如--plugin=protoc-gen-grpc=/usr/local/bin/grpc_cpp_plugin）。
如果你有多个版本的protobuf，请检查是否同时使用了相同版本的protoc和插件。
英文:
Check your /usr/local/bin. It should be there along with plugins for other languages.

If you do have other plugins but not cpp you probably overlooked something while installing.
If it's there try to specify full path when compiling (i.e. --plugin=protoc-gen-grpc=/usr/local/bin/grpc_cpp_plugin)
If you have multiple version of protobuf check if you use protoc and plugin from the same one.
