1# gRPC-Go 2 3[![Build Status](https://travis-ci.org/grpc/grpc-go.svg)](https://travis-ci.org/grpc/grpc-go) [![GoDoc](https://godoc.org/google.golang.org/grpc?status.svg)](https://godoc.org/google.golang.org/grpc) [![GoReportCard](https://goreportcard.com/badge/grpc/grpc-go)](https://goreportcard.com/report/github.com/grpc/grpc-go) 4 5The Go implementation of [gRPC](https://grpc.io/): A high performance, open source, general RPC framework that puts mobile and HTTP/2 first. For more information see the [gRPC Quick Start: Go](https://grpc.io/docs/quickstart/go.html) guide. 6 7Installation 8------------ 9 10To install this package, you need to install Go and setup your Go workspace on your computer. The simplest way to install the library is to run: 11 12``` 13$ go get -u google.golang.org/grpc 14``` 15 16Prerequisites 17------------- 18 19This requires Go 1.6 or later. Go 1.7 will be required soon. 20 21Constraints 22----------- 23The grpc package should only depend on standard Go packages and a small number of exceptions. If your contribution introduces new dependencies which are NOT in the [list](http://godoc.org/google.golang.org/grpc?imports), you need a discussion with gRPC-Go authors and consultants. 24 25Documentation 26------------- 27See [API documentation](https://godoc.org/google.golang.org/grpc) for package and API descriptions and find examples in the [examples directory](examples/). 28 29Performance 30----------- 31See the current benchmarks for some of the languages supported in [this dashboard](https://performance-dot-grpc-testing.appspot.com/explore?dashboard=5652536396611584&widget=490377658&container=1286539696). 32 33Status 34------ 35General Availability [Google Cloud Platform Launch Stages](https://cloud.google.com/terms/launch-stages). 36 37FAQ 38--- 39 40#### Compiling error, undefined: grpc.SupportPackageIsVersion 41 42Please update proto package, gRPC package and rebuild the proto files: 43 - `go get -u github.com/golang/protobuf/{proto,protoc-gen-go}` 44 - `go get -u google.golang.org/grpc` 45 - `protoc --go_out=plugins=grpc:. *.proto` 46
