I'm using Windows 10. Before I install git 2.6.1.windows.1, I have installed git 1.9.5.github.0 (by installing GitHub Desktop), it works just fine. But when I installed git 2.6.1.windows.1 (from git-scm.com), I'm not able to use git anymore: - The powershell console displayed [(unknown)] instead of [master], even when I changed working directory to my project, it still display [(unknown)] - When I "git add" (or "git commit", "git push"), It told me an error: "fatal: Not a git repository: 'C:\Program Files\Git'" After that, I returned to the old version of git - git 1.9.5.github.0, but the fault still there. I think git didn't change its working directory, I have no idea. Now, I'm not able to work with git. Please response me as soon as possible, thanks. -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
