go version：go版本go1.14 linux / amd64

go.mod

module [redacted]

go 1.14

require (
    github.com/golang/protobuf v1.4.0-rc.2
    google.golang.org/grpc v1.27.1
    google.golang.org/protobuf v1.20.0 // indirect
)

我正在运行以下命令：

protoc -I ./src/pbdefs/protos/ --go-grpc_out=. src/pbdefs/protos/*.proto

从.proto文件生成我的GRPC输出文件，出现错误

protoc-gen-go-grpc: program not found or is not executable
