我是 go lang 開發(fā)的初學(xué)者，我嘗試從 go 服務(wù)器連接云 oracle 數(shù)據(jù)庫（使用 'github.com/godror/godror' 包）。我安裝了 Oracle 即時客戶端并設(shè)置了環(huán)境路徑。Go 服務(wù)器正在運行并且能夠建立連接和查詢。但是當(dāng)我構(gòu)建一個生產(chǎn)應(yīng)用程序時出現(xiàn)了這些錯誤。命令：env GOOS=linux GOARCH=amd64 go build -o odb db_main.go../github.com/godror/godror/orahlp.go:452:53: undefined: VersionInfo../github.com/godror/godror/orahlp.go:461:53: undefined: VersionInfo../github.com/godror/godror/orahlp.go:479:19: undefined: VersionInfo../github.com/godror/godror/orahlp.go:480:19: undefined: VersionInfo../github.com/godror/godror/orahlp.go:481:30: undefined: ObjectType../github.com/godror/godror/orahlp.go:482:31: undefined: Event../github.com/godror/godror/orahlp.go:482:42: undefined: SubscriptionOption../github.com/godror/godror/orahlp.go:482:64: undefined: Subscription../github.com/godror/godror/orahlp.go:483:10: undefined: StartupMode../github.com/godror/godror/orahlp.go:484:11: undefined: ShutdownMode../github.com/godror/godror/orahlp.go:484:11: too many errors```My server code(db_main.go)```package mainimport (    "database/sql"    "encoding/json"    "fmt"    "log"    "net/http"    "time"_ "github.com/godror/godror")//  VersionInfo,ObjectType,Event,SubscriptionOption,Subscription,StartupMode,ShutdownModevar db *sql.DBfunc main() {    var err error    db, err = sql.Open("godror", "xyz/abc@13.43.11.8:1521/sampledb")    if err != nil {        log.Println("Error")        fmt.Println(err)        return    }    defer db.Close()    port := ":8000"    http.HandleFunc("/insert", InsertData)    http.HandleFunc("/list", GetList)    log.Println("Tranzo-Shahi Oracle DB running in ", port)    httpErr := http.ListenAndServe(port, nil)    if httpErr != nil {        log.Println("Tranzo-Shahi Oracle DB Error: ", httpErr.Error())    }}
