Go语言: Error during compilation

Question

我正在尝试在 Windows 10 上编译这个用 Go 编写的程序，但出现以下错误:

warpwallet_cracker.go:12:2: cannot find package "github.com/vsergeev/btckeygenie/btckey" in any of:
        C:\Go\src\github.com\vsergeev\btckeygenie\btckey (from $GOROOT)
        C:\Users\user\go\src\github.com\vsergeev\btckeygenie\btckey (from $GOPATH)
warpwallet_cracker.go:4:5: cannot find package "golang.org/x/crypto/pbkdf2" in any of:

warpwallet_cracker.go:5:2: cannot find package "golang.org/x/crypto/scrypt" in any of:

代码如下:

package main

import (
    "golang.org/x/crypto/pbkdf2"
    "golang.org/x/crypto/scrypt"
    "bytes"
    "crypto/sha256"
    "fmt"
    "time"
    "os"
    "math/rand"
    "github.com/vsergeev/btckeygenie/btckey"
)

const letterBytes = "0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ"
func random(r *rand.Rand, n int) string {
    b := make([]byte, n)
    for i := range b {
        b[i] = letterBytes[r.Intn(62)]
    }

    return string(b)
}

func main () {
    r := rand.New(rand.NewSource(time.Now().Unix()))

    var address string
    saltValue := ""

    if len(os.Args) >= 2 {
        address = os.Args[1]
        if len(os.Args) == 3 {
            saltValue = os.Args[2]
        } else {
            saltValue = "";
        }
    } else {
        fmt.Printf("Usage: %s [Address] [Salt - optional]\n\n", os.Args[0])
        os.Exit(0)
    }

    fmt.Printf("Using address \"%s\" and salt \"%s\"\n", address, saltValue)

    tries := 0
    start := time.Now()
    for {
        passphraseValue := random(r, 8)
        result := bruteforce(passphraseValue, saltValue, address);
        if result != "" {
            fmt.Printf("Found! Passphrase %s\n", passphraseValue)
            os.Exit(0)
        } else {
            tries += 1
            fmt.Printf("\rTried %d passphrases in %s [last passphrase: %s]", tries, time.Since(start), passphraseValue)
        }
    }
}

func bruteforce(passphraseValue string, saltValue string, address string) string {
    var priv btckey.PrivateKey
    var err error

    pass := fmt.Sprint(passphraseValue, "\x01")
    salt := fmt.Sprint(saltValue, "\x01")
    key, _ := scrypt.Key([]byte(pass), []byte(salt), 262144, 8, 1, 32)
    pass = fmt.Sprint(passphraseValue, "\x02")
    salt = fmt.Sprint(saltValue, "\x02")
    key2 := pbkdf2.Key([]byte(pass), []byte(salt), 65536, 32, sha256.New)

    var result bytes.Buffer
    for i := 0; i < len(key); i++ {
        result.WriteByte(key[i] ^ key2[i])
    }

    err = priv.FromBytes(result.Bytes())
    if err != nil {
        fmt.Printf("Error importing private key: %s [%s]\n", err, passphraseValue)
        return ""
    }

    address_uncompressed := priv.ToAddressUncompressed()

    if (address_uncompressed == address) {
        return passphraseValue
    }

    return ""
}

我不知道是什么问题，谁能帮帮我？

您需要使用“go get”命令安装依赖项。

如错误消息中所述，您没有安装依赖项。 仔细查看错误消息，您会收到三个不同的错误。不属于 go 标准库的每个包一个。

当您尝试导入不属于 go 标准库的包时，go 编译器会在 $GOROOT 路径和 $GOPATH 路径下查找，以尝试找到与您尝试导入的名称匹配的包。如果未找到，编译器将抛出您在上面看到的错误。正如@Adrian 所说，您可以运行:

去获取./...

自动下载所有依赖项。
