createinstallmedia: command not found

My OS now is Sierra, I want to create a bootable installer for "EI Captian".

I use the command below, and it turns out "sudo: /Applications/Install OS X EICaptian.app/Contents/Resources/createinstallmedia: command not found".

sudo /Applications/Install\ OS\ X\ EI\Captian.app/Contents/Resources/createinstallmedia --volume /Volumes/Captian --applicationpath /Applications/Install\ OS\ X\ EI\Captian.app --nointeraction

The same happened when I intend to create a bootable installer for "Sierra". (Once I thought it may not be allowed to create a lower version OS installer on a higher OS ?! )

So, how can I solve it?! I want to create a bootable installer on my "Sierra".

MacBook Air (13-inch, Early 2015)

You can make a bootable USB stick to install using this free program which will do all the work for you.

Thanks again!!! My createinstallmedia is just in the right place when I checked as you said. Every files seemed just right. I did not do anything to change them though.

I have tried everything those past days. Use command, use tools as guys mentioned in other answers.

But, none of them succeed...neither on my mac mini in my company and my MacBook air...

I even bought a new flash driver this morning.I used command to create a installer, and I got "Error erasing disk error number(-69888,0)". I used "DiskMaker X 6" , I got "This disk could not be created because of an error: An error occurred:-10006".

(Can't upload a image, don't know why.)

Maybe something wrong with my current OS? Maybe I just cannot make a installer from my "Sierra"?

...by the way, my Mac mini can't be use now, thanks to myself... - -||
