从golang程序安装npm

Question

I need to run npm install on folder that I was created

Im doing the following

command := exec.Command("../app/node/", "npm", "install")
command.Dir = "."
output, err := command.Output()
if err != nil {
    log.Println(err)
}
fmt.Printf("%s", output)

And I get error :

fork/exec ../app/node/: permission denied

Any idea how to overcome this?

You've got your arguments to Command in the wrong order. Per the documentation, the first argument is the program to be executed (i.e. npm), the following arguments are the parameters to pass, in the order that command should receive them, e.g.:

command := exec.Command("npm", "install", "../app/node/")
