解决go语言google.golang.org/grpc 超时问题

官方安装命令 go get google.golang.org/grpc
国内安装不起 package google.golang.org/grpc: unrecognized import path "google.golang.org/grpc"(https fetch: Get https://google.golang.org/grpc?go-get=1: dial tcp 216.239.37.1:443: i/o timeout)
原因是 代码已经转移到github上面了   包依赖还是没有修改 还是google.golang.org这种
正确的安装方式
git clone https://github.com/grpc/grpc-go.git $GOPATH/src/google.golang.org/grpc
git clone https://github.com/golang/net.git $GOPATH/src/golang.org/x/net
git clone https://github.com/golang/text.git $GOPATH/src/golang.org/x/text
go get -u github.com/golang/protobuf/{proto,protoc-gen-go}
git clone https://github.com/google/go-genproto.git $GOPATH/src/google.golang.org/genproto
cd $GOPATH/src/
go install google.golang.org/grpc

在windows平台$GOPATH修改为%GOPATH%
git clone https://github.com/grpc/grpc-go.git %GOPATH%/src/google.golang.org/grpc
git clone https://github.com/golang/net.git %GOPATH%/src/golang.org/x/net
git clone https://github.com/golang/text.git %GOPATH%/src/golang.org/x/text
go get -u github.com/golang/protobuf/{proto,protoc-gen-go}
git clone https://github.com/google/go-genproto.git %GOPATH%/src/google.golang.org/genproto
cd %GOPATH%/src/
go install google.golang.org/grpc
