Numeric Citation with Biblatex does not work?

Question

I am trying to cite with the numeric style in latex, but that doesn't work for me. I referenced the biblatex Package in the following way:

'\usepackage[
'backend=biber, 
'style = numeric-comp,
'citestyle=numeric-comp,%numeric, 
'%  bibstyle=ieee,
'%  doi=false,
'%  isbn=false,
'url=false]{biblatex}           
'%\addbibresource{refs} 
'\bibliography{refs}

and cited in the following way:

Text... \cite{Copil.2016}

And the citation result is:

Text... [Copil.2016]

I Would lkike to have the Citation as follows:

Text... [1]

Does anybody know the solution for my problem?

Answer 1

As you have already mentioned yourself, you have to configure your Tex editor (e.g. TeXstudio) to use biber.

You can do that by going to

Options > Configure TeXstudio > Build > Default Bibliography > Biber

Then you have to configure the command in options if it isn't set by default.

Options > Configure TeXstudio > Commands > Biber > Choose file > (in Debian) /usr/bin/biber
