If I

fsi

than FSI starts normally.

we don't bundle fsi anymore. Is it installed? Can we find it in any of the paths listed under https://github.com/fsharp/FAKE/blob/master/src/app/FakeLib/FSIHelper.fs#L14 ?

I would suggest calling FAKE instead of FSI for the documentation generation (ie changing the documentation generation to a FAKE script). This way you don't need fsi, FAKE will cache the script and you don't need defines for multiple documentation scenarios (just multiple FAKE tasks).

I did the change on projectscaffold some time ago here: fsprojects/ProjectScaffold@6e4a6b6

Updated the script, everything works. Thanks!
