Too many make error

[fbsduser]

I'm trying to make this project from source and i faced too many errors with python scripts
ex :
File "/home/USER/hack/esp_wifi_repeater/../esp-open-sdk/xtensa-lx106-elf/bin/esptool.py", line 454
if first_flash_size_freq != self.flash_size_freq:
IndentationError: expected an indented block
make: *** [Makefile:133: firmware/0x02000.bin] Error
The compile proc for "esp-open-sdk" was successful and now i don't know why the cloned sources has this issue.
