mac上生成go文件失敗報錯，gRpc-- protoc-gen-go: program not found or is not executable

根據proto文件生成對應的go文件

搭建grpc環境

brew tap grpc/grpc
brew install protobuf
go get -u github.com/golang/protobuf/proto
go get -u github.com/golang/protobuf/protoc-gen-go

生成go文件命令

protoc --go_out=plugins=grpc:. *.proto

• 執行命令時報錯：

protoc-gen-go: program not found or is not executable
Please specify a program using absolute path or make sure the program is available in your PATH system variable
--go_out: protoc-gen-go: Plugin failed with status code 1.

• 解決方案
  找到protoc-gen-go 文件，執行以下命令，該文件通過go get安裝時會安裝在$GOPATH/go/bin目錄下
  cp protoc-gen-go /usr/local/bin/
  然后vim ~/.bash_profile
  export GOPATH=$HOME/go PATH=$PATH:$GOPATH/bin

之后source ~/.bash_profile即可
