I accidently remote base on my suse 😦 . I want my zypper back! Fortunately rpm still exists.
So I download zypper rpm from internet, and it has some dependencies.
gpg2-2.0.24-8.1.x86_64.rpm
libcurl4-7.37.0-36.1.x86_64.rpm
libzypp-15.24.2-42.1.x86_64.rpm
zypper-1.12.50-40.3.x86_64.rpm
rpm -i package-name.rpm installs the package.
then zypper install -t patter base install the base package.
