在powershell命令行里依次运行
1.
(new-object Net.WebClient).DownloadString("http://psget.net/GetPsGet.ps1") | iex
2.
install-module posh-git
如果你的系统是64位的，可能会报错
"D:我的资料库DocumentsWindowsPowerShellModules" is added to the PSModulePath environment variable Creating PowerShell profile... D:我的资料库DocumentsWindowsPowerShellNuGet_profile.ps1 Could not find git command. Please create a git alias or add %ProgramFiles%Gitcmd to PATH. Module posh-git was successfully installed. git command could not be found. Please create an alias or add it to your PATH.
这时只要在系统环境变量里加入如下命令即可
变量名：GIT_DIR
变量值：C:Program Files (x86)Gitcmd
注意变量值为你系统安装git的路径位置
