我想像从终端一样执行命令。 cd path; ./configure; make 所以我需要按顺序运行每个命令并在继续之前等待最后一个命令完成。使用我当前版本的代码，它目前说./configure: no such file or directory我认为这是因为 cd path 执行并在新的 shell 中执行 ./configure，而不是在上一个命令的同一目录中。有任何想法吗？ 更新我通过更改工作目录然后执行 ./configure 和 make 命令解决了这个问题
err = os.Chdir(folderPath)
if err != nil {
fmt.Println("File Path Could not be changed")
os.Exit(1)
}
现在我仍然很想知道是否有办法在同一个 shell 中执行命令。
