This command:
这个命令：

.. outputs this message:
.. 输出此消息：
del: executable file not found in %path%
del: 在 %path% 中找不到可执行文件

I got the same error as you.
But dystroy is correct: You can't run delor any other command built into cmdbecause there is no del.exefile (or any other del-executable for that matter).
我和你有同样的错误。但是dystroy 是正确的：您不能运行del或内置任何其他命令，cmd因为没有del.exe文件（或任何其他可执行的文件）。
I got it to work with:
我让它与：
package main
import(
"fmt"
"os/exec"
)
func main(){
c := exec.Command("cmd", "/C", "del", "D:\a.txt")
if err := c.Run(); err != nil {
fmt.Println("Error: ", err)
}
}

You need a Windows cmd to execute your dircommand.
您需要一个 Windows cmd 来执行您的dir命令。
Try this :
尝试这个 ：
cmd := exec.Command("cmd", "/C", "dir").Output()
(sorry, no Windows computer to check it right now)
（抱歉，现在没有 Windows 计算机可以检查它）

In case you need the output of cmd:
如果您需要 cmd 的输出：
if c, err := exec.Command("cmd","/c","del","a.txt").CombinedOutput(); err != nil {
log.Fatal(err)
} else {
fmt.Printf("%s\n", c)
}

Found another solution too. Create a batch file that contains the following: del c:\aaa.txt
也找到了另一个解决方案。创建一个包含以下内容的批处理文件：del c:\aaa.txt
Then call it like this:
然后像这样调用它：
exec.Command("c:\del.bat").Run()

Ok let's see, according to the documentation, in windows, processes receive commands as a single line string and do some parsing of their own. Exec's Command function builds the command string by combining all arguments together using CommandLineToArgvW, that despite being the most common quoting algorithm doesn't work for every application. Applications like msiexec.exe and cmd.exe use an incompatible unquoting algorithm, hence the extra mile. Heres a different example using powershell
好的，让我们看看，根据文档，在 Windows 中，进程将命令作为单行字符串接收并进行一些自己的解析。Exec 的 Command 函数通过使用 CommandLineToArgvW 将所有参数组合在一起来构建命令字符串，尽管它是最常见的引用算法，但并不适用于每个应用程序。像 msiexec.exe 和 cmd.exe 这样的应用程序使用不兼容的取消引用算法，因此需要额外的努力。这是使用 powershell 的不同示例
package main
import (
"os/exec"
"fmt"
"log"
)
func main() {
out, err := exec.Command("powershell","remove-item","aaa.txt").Output()
if err != nil {
log.Fatal(err)
} else {
fmt.Printf("%s",out)
}
