Sounds like you are running a recent kernel that has finally removed the long deprecated sysfs GPIO interface.

You could either build a custom kernel with CONFIG_GPIO_SYSFS enabled or switch to the new(er) GPIO character device userspace API, so libgpiod and its associated tools in the gpiod package. Of those, gpioset is used to set a line as output.
