etcd包导入坑-木庄网络博客

测试案例上导入的是 go.etcd.io/etcd/clientv3 , 但是go.etcd.io/etcd/clientv3 无法go get，会timeout。

这个时候会选择在github.com拉取github.com/etcd-io/etcd, 然后进行测试就会发现进入另一个坑，会报错

错误一:

```

$GOPATH/src/go.etcd.io/etcd/clientv3/balancer/picker/err.go:25:9: cannot use &errPicker literal (type *errPicker) as type Picker in return argument:

*errPicker does not implement Picker (wrong type for Pick method)

have Pick(context.Context, balancer.PickInfo) (balancer.SubConn, func(balancer.DoneInfo), error)

want Pick(balancer.PickInfo) (balancer.PickResult, error)

$GOPATH/src/go.etcd.io/etcd/clientv3/balancer/picker/roundrobin_balanced.go:33:9: cannot use &rrBalanced literal (type *rrBalanced) as type Picker in return argument:

*rrBalanced does not implement Picker (wrong type for Pick method)

have Pick(context.Context, balancer.PickInfo) (balancer.SubConn, func(balancer.DoneInfo), error)

want Pick(balancer.PickInfo) (balancer.PickResult, error)

```

错误二：

```

../../../../etcd-io/etcd/clientv3/auth.go:121:72: cannot use auth.callOpts (type []"github.com/etcd-io/etcd/vendor/google.golang.org/grpc".CallOption) as type []"go.etcd.io/etcd/vendor/google.golang.org/grpc".CallOption in argument to auth.remote.AuthEnable

../../../../etcd-io/etcd/clientv3/auth.go:126:74: cannot use auth.callOpts (type []"github.com/etcd-io/etcd/vendor/google.golang.org/grpc".CallOption) as type []"go.etcd.io/etcd/vendor/google.golang.org/grpc".CallOption in argument to auth.remote.AuthDisable

../../../../etcd-io/etcd/clientv3/auth.go:131:152: cannot use auth.callOpts (type []"github.com/etcd-io/etcd/vendor/google.golang.org/grpc".CallOption) as type []"go.etcd.io/etcd/vendor/google.golang.org/grpc".CallOption in argument to auth.remote.UserAdd

../../../../etcd-io/etcd/clientv3/auth.go:136:144: cannot use auth.callOpts (type []"github.com/etcd-io/etcd/vendor/google.golang.org/grpc".CallOption) as type []"go.etcd.io/etcd/vendor/google.golang.org/grpc".CallOption in argument to auth.remote.UserAdd

```

错误原因是直接拉取github.com/etcd-io/etcd，不是release版本，没有严格的测试或者是开发版本。所以会报错

这个时候去https://github.com/etcd-io/etcd/releases下面，拉取release版本，然后放在go.etcd.io/etcd/*下面就可以测试通过
