Check #77

If you want a quick fix, go to C:\Ruby24-x64\lib\ruby\gems\2.4.0\gems\git_stats-1.0.17 and change lib/git_stats/git_data/repo.rb:49 to:

@commits ||= run_and_parse("git rev-list --pretty=format:%h^|%at^|%ai^|%aE #{commit_range} #{tree_path} | grep -v commit").map do |commit_line|

Also, it's worth fixing the lib/git_stats/stats_view/view.rb:31 to get the author_details generated:

active_page: "authors/#{author.dirname}/#{template}")

[liushibin]

@colonelchlorine it's is a nice fix.

@liushibin @colonelchlorine I use win server 2012
I tried the quick fix you mentioned but prompted:
'grep' is not recognized as an internal or external command,
operable program or batch file.
