I decided to use git rebase -i HEAD~3 to merge the three commits, but I got the following error (below). Help solve this problem.
$ git rebase -i HEAD ~ 3
/ mingw64 / libexec / git-core / git-rebase - interactive: eval: line 255: syntax error near unexpected token '('
/ mingw64 / libexec / git-core / git-rebase - interactive: eval: line 255: 'C: / Program Files (x86) / Microsoft Visual Studio 14.0 / Common7 / IDE / devenv.exe "$ @"'
Additional Information:
I use GitExtensions as a wrapper for working with git and tied vsdiffmerge as a merge tool to this case.
I do not know why, but the message indicates the installation path of Visual Studio. Visual Studio Version: 2015 Update 3.
