go - 即使包存在，Dep init 也会失败

Question

我正在尝试使用 dep 打包一个 go 应用程序，并且在执行 dep init 时出现以下错误。

我已经从这里安装了 amcl 库 - https://github.com/milagro-crypto/amcl/tree/master/version3/go

连下面的包都存在

nithin@XPS-L401X:~/go/src/github.com/milagro-crypto/amcl/version3/go/amcl/FP256BN$ ls
ARCH.go  BIG.go  DBIG.go  ECDH.go  ECP2.go  ECP.go  FP12.go  FP2.go  FP4.go  FP.go  MPIN.go  PAIR.go  ROM.go

但我仍然得到以下错误

Answer 1

我找到了答案。

首先去获取github.com/milagro-crypto/amcl

然后 cd 到这个位置(基于你的 $GOPATH)github.com/milagro-crypto/amcl/version3/go

按照此说明安装 milagro
https://github.com/milagro-crypto/amcl/tree/master/version3/go

我建议一个接一个地安装所有选项，然后不要忘记

去运行TestALL.go

和

去运行BenchtestALL.go

否则无法解决，我知道为什么。
