我正在尝试安装 Minikube，即使在安装过程中没有错误，我仍然无法运行它：

QueryReference 和 Snapshot 之间的实际区别是什么？当使用 get() 和 data() 等方法时，我有点困惑。对我来说，两者似乎都喜欢从商店返回数据。

上面是我的 Laravel monolog 示例日志数据。我正在使用 Logstash 读取日志数据并将其发送到 Elasticsearch。下面是我的logstash.conf 文件

Go中的值语义和指针语义是什么意思？在本课程中,作者在解释数组和切片的内部时,曾经多次提及上述术语,我完全无法理解.

当我尝试在 Mac 上启动 minikube 时，出现以下错误。

命令 ：minikube start

无效配置：[由于打开 /Users/sathishkumar/.minikube/profiles/minikube/client.crt，无法读取 minikube 的 client-cert /Users/sathishkumar/.minikube/profiles/minikube/client.crt：没有此类文件或目录，由于打开 /Users/sathishkumar/.minikube/profiles/minikube/client.key，无法读取 minikube 的客户端密钥 /Users/sathishkumar/.minikube/profiles/minikube/client.key：没有这样的文件或目录]

解决这个问题的办法是什么？

我想知道该程序输出背后的原因。

package main

程序

import (
    "fmt"
)

func main() {
    a := 1_00_000
    fmt.Println(a)
}

输出量

100000

下划线如何在输出中被忽略。Go中此新功能的用途是什么？
