protoc --go_ou執行出錯Please specify a program using absolute path or make sure the program is available

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

執行指令時報錯：

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 檔案，執行以下指令，該檔案通過go get安裝時會安裝在$GOPATH/go/bin目錄下
cp protoc-gen-go /usr/local/bin/
然後vim ~/.bash_profile
export GOPATH=$HOME/go PATH=$PATH:$GOPATH/bin
之後source ~/.bash_profile即可
