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 have El\Captian in your sudo command instead of El\ Capitan with a space after the \. Just fix those 2 misspellings/spacing and try again. Make sure El is E L not E I(eye).


Yours:

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

Should be:

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

For Sierra it should be (make sure your external volume name is Sierra for the following to work):

sudo /Applications/Install\ macOS\ Sierra.app/Contents/Resources/createinstallmedia --volume /Volumes/Sierra --applicationpath /Applications/Install\ macOS\ Sierra.app --nointeraction

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... - -||

Sudo / Applications / Install \ OS \ X \ Mavericks.app/Contents/Resources/createinstallmedia --volume / Volumes / MyVolume --applicationpath / Applications / Install \ OS \ X \ Mavericks.app

If that is the exact command you used, then it will fail as you have put spaces in front of every escape character (\)

There should be no space before the escape character ( \ )

If you copy and paste from the link I posted above, it will be formatted correctly.
