If your then spouse is out of the US when you sponsor her, the only path is for her to consular process. Since she will have left the US after being married and did not file for a green card in the US, there is not a question of visa fraud/misrepresentation. Therefore based on the facts you have given, you would then do the three step process for her, she would obtain her immigrant visa at the US consulate in Paris and then be processed for her green card upon first entry.
