kubectl-plugins: get errors while the ssh command invoking

Hello, I followed the README guide to run the tool (on the master branch) and got several errors. Did I use it in the wrong way? please help, thanks a lot.

I am using k8s 1.13.5 as below:

kubectl version
Client Version: version.Info{Major:"1", Minor:"13", GitVersion:"v1.13.4", GitCommit:"c27b913fddd1a6c480c229191a087698aa92f0b1", GitTreeState:"clean", BuildDate:"2019-02-28T13:37:52Z", GoVersion:"go1.11.5", Compiler:"gc", Platform:"linux/amd64"}
Server Version: version.Info{Major:"1", Minor:"13", GitVersion:"v1.13.5", GitCommit:"2166946f41b36dea2c4626f90a77706f426cdea2", GitTreeState:"clean", BuildDate:"2019-03-25T15:19:22Z", GoVersion:"go1.11.5", Compiler:"gc", Platform:"linux/amd64"}

when I install the plugins, it shows:

root@robota:~/kubectl-plugins# ./install-plugins.sh

Done.
Please open a new terminal or run: source ~/.bash_profile

The following kubectl-compatible plugins are available:

kubectl image
kubectl ip
kubectl prompt
kubectl ssh
kubectl switch
kubectl uptime

when I run the commands, it shows these:

kubectl ssh -n gitlab-managed-apps -u root -p runner-gitlab-runner-789c484674-bfdtd

@TAnas0 @machine424 @zhang-shengping i pushed a commit to master that I hope will fix the issue. Could you pull down the latest, reinstall and try again? If you see an error again, please provide logs. Much appreciated.
