Because I want to document an api I have, I looked around and found a solution called apidoc which uses node. I have created a node "area" in jk_init.ini: [node] comment = NodeJS executables = /usr/bin/npm, /usr/bin/node, /usr/bin/nodejs directories = /usr/lib/nodejs/, /usr/share/node-mime One problem I now has is that after I upgraded node, the version on the server is 7.4.0, while in the jail it is 0.10.25. I have tried to run the jk_init and the jk_update commands, but without much luck. Has anyone experienced something similar and how did you fix it? Btw: It could be this is the wrong forum area, but since it is related to ispconfig (broadly), I decided to post it here. If this was a wrong decision, I am sorry.
