Exactly man I encountered the same issue while trying to install this tool and turns out the error I was getting was:

package https:/github.com/takshal/freq: https:/github.com/takshal/freq: invalid import path: malformed import path "https:/github.com/takshal/freq": invalid char ':' ----> an Invalid char ':'
