[elgs]

Thanks for report this problem. I just had a quick look, it looks like the fsnotify dependency I have using have been migrated to another project. I need sometime to load everything back to my brain. By the way, what is the OS that you were running this program on?

[cheneylew]

max os x: 10.12.6 ; go version go1.8 darwin/amd64;

[cheneylew]

hi, do you have any progress?

[elgs]

Sorry for the late reply. I found the code on the Github seems to be much older than the code in my computer. I have just updated the code and would you please get the latest code and try again? Thanks.
