Go 为什么此代码在运行命令 error="exec： not started" 时出现错误

下面是我的代码(writeFromProcessToFileWithMax是一个内部函数，工作正常):

    // Go routines for non-blocking reading of stdout and stderr and writing to files
    g := new(errgroup.Group)

    // Read stdout in goroutine.
    g.Go(func() error {
        err = writeFromProcessToFileWithMax(stdoutScanner, stdoutFileWriter, maxStdoutFileLengthInGB)
        if err != nil {
            log.Error().Err(err).Msgf("Error writing to stdout file: %s", stdoutFilename)
            return err
        }
        return nil
    })

    // Read stderr in goroutine.
    g.Go(func() error {
        err = writeFromProcessToFileWithMax(stderrScanner, stderrFileWriter, maxStderrFileLengthInGB)
        if err != nil {
            log.Error().Err(err).Msgf("Error writing to stderr file: %s", stderrFilename)
            return err
        }
        return nil
    })

    // Wait the command in a goroutine.
    g.Go(func() error {
        return cmd.Wait()
    })

    // Starting the command
    if err = cmd.Start(); err != nil {
        log.Error().Err(err).Msg("Error starting command")
        return err
    }

    // Waiting until errorGroups groups are done
    if err = g.Wait(); err != nil {
        log.Error().Err(err).Msg("Error during running of the command")
    }

当我运行它时，我得到以下错误=Error during running of the command error="exec: not started".但一切都运行正常.

它会回来咬我还是我应该压抑？
