Unable to convert : dcraw not found

[Kitof]

Hi,

I'm unable to convert .NEF to . JPG after a fresh docker install :

convertx  | stderr: sh: dcraw: not found
convertx  | gm convert: "dcraw" -c -w -6 -T "./data/uploads/1/1/DSC_0880.NEF" > "/tmp/gmSkKQBu".
convertx  | gm convert: Delegate failed ("dcraw" -c -w -6 -T "%i" > "%o").
convertx  | 
convertx  | Failed to convert ./data/uploads/1/1/DSC_0880.NEF from nef to jpeg using graphicsmagick. error: Error: Command failed: gm convert "./data/uploads/1/1/DSC_0880.NEF" "./data/output/1/1/DSC_0880.jpg"
convertx  | sh: dcraw: not found
convertx  | gm convert: "dcraw" -c -w -6 -T "./data/uploads/1/1/DSC_0880.NEF" > "/tmp/gmSkKQBu".
convertx  | gm convert: Delegate failed ("dcraw" -c -w -6 -T "%i" > "%o").

Any helps appreciated, thanks.
