Rails: Why "sudo" command is not recognized?

Question

In my application directory (on Windows) I run:

sudo pdfkit --install-wkhtmltopdf

as explained here, but I got this error:

'sudo' is not recognized as an internal or external command, operable program or batch file.

What could be the problem ?

Sudo is a Unix specific command designed to allow a user to carry out administrative tasks with the appropriate permissions.

Windows does not have (need?) this.

Run the command with the sudo removed from the start.

I tried to run `pdfkit --install-wkhtmltopdf` but now the `pdfkit` command is not recognized. `gem list` shows that I do have the `pdfkit` gem installed. Any ideas ? – Misha Moroshko Mar 03 '11 at 00:21
It sounds like PDFkit is not in your PATH. Try navigating to the gem directory and running it from there. – Douglas F Shearer Mar 17 '11 at 14:45

sudo is a Unix/Linux command. It's not available in Windows.

That you are running Windows. Read:

http://en.wikipedia.org/wiki/Sudo

It basically allows you to execute an application with elevated privileges. If you want to achieve a similar effect under Windows, open an administrative prompt and execute your command from there. Under Vista, this is easily done by opening the shortcut while holding Ctrl+Shift at the same time.

That being said, it might very well be possible that your account already has sufficient privileges, depending on how your OS is setup, and the Windows version used.

Please see my comment above. `pdfkit --install-wkhtmltopdf` doesn't work either. Any ideas why ? — Misha Moroshko, Mar 03 '11 at 00:30

sudo is used for Linux. It looks like you are running this in Windows.

Yes, windows don't have sudo on its terminal. Try using pip instead.

Install pip using the steps here.
type pip install [package name] on the terminal. In this case, it may be pdfkit or wkhtmltopdf.

Analogue to sudo in Windows is running command prompt "As Administrator" by right-clicking on it's link. Then everything you run in it will be "sudo-ed".
