转到安装“不允许导入周期”

Question

Folks- I'm not able to understand this:

My code layout:

src/rtagent/rtagent.go (has package main)

src/simplerouter/simplerouter.go (has package simplerouter)

src/p4/p4runtime.pb.go (has package p4)

rtagent.go:

package main
import (
    "fmt"
    "golang.org/x/net/context"
    "google.golang.org/grpc"
    "google.golang.org/grpc/reflection"
    "io"
    "log"
    "net"
    "p4"
    "simplerouter"
    p4_config "p4/config"
)

simplerouter.go

package simplerouter
import (
    "encoding/binary"
    "errors"
    "fmt"
    "p4"
    "p4InfoUtils"
    "strings"
    "unsafe"
)

p4runtime.pb.go

package p4
import proto "github.com/golang/protobuf/proto"
import fmt "fmt"
import math "math"
import google_protobuf "github.com/golang/protobuf/ptypes/any"
import google_rpc "google.golang.org/genproto/googleapis/rpc/status"
import p4_config "p4/config"
import p41 "p4"
import (
    context "golang.org/x/net/context"
    grpc "google.golang.org/grpc"
)

I get this error:

go install rtagent
import cycle not allowed
package rtagent
        imports p4
        imports p4

Could someone please help?

Answer 1

The error message pretty much says it all:

rtagent imports p4 which in turn imports p4 (itself). This is not allowed.

Your code makes this obvious, too:

package p4
// <snip>
import p41 "p4"  // <-- importing itself
