Yes, it’s setup in a counterintuitive way, I too struggled first time I tried to build the go part.
Do you have ratel/server/bindata.go in you working directory?
If not something went wrong while running the build script. were there any error messages?
Found the reason for this. I originally cloned ratel to fix some issue on the javascript code. So I was trying to build it from outside the gopath and ratel was not installed in the gopath.
@smeadows-abbundefined: Asset used to be a symptom of missing go-bindata. Other thing Martin has mentioned is having to build Ratel from inside $GOPATH.
In my case working folder for ratel is ~/go/src/github.com/dgraph-io/ratel.
Feel free to ping me on Dgraph Community Slack if you need help troubleshooting this, my slack handle there is same as my Github handle.
Users sometimes mention this build issue, but I couldn’t reproduce it yet and still looking for an automatic way to detect and/or fix it.
