After installing OS X El Capitan on my computer I noticed that fsharp interactive failed to start because it failed to locate mono:
/Library/Frameworks/Mono.framework/Versions/4.0.4/bin/fsharpi: line 24: exec: mono: not found Session termination detected. Press Enter to restart.
If we look at the file at that position we find that it assumes that mono is in the path. I checked /etc/paths, and it looked correct (i.e. based on the paths file, mono should have been in the path):
mathieu$ which mono /usr/local/bin/mono mathieu$ ls -la /usr/local/bin/mono lrwxr-xr-x 1 mathieu admin 48 Sep 12 21:56 /usr/local/bin/mono -> /Library/Frameworks/Mono.framework/Commands/mono
I’ve found that there is a stackoverflow answer. I opted for a somewhat different approach and created a file in my ~/bin folder with essentially the same fix (this was before the stackoverflow answer, so it’s not exactly alike). You can find it here.
After that I changed the xamarin studio f# interactive settings so that the path is ~
I’m thinking that later on I want to change the settings for fsharpi and fsharp to point to a local nuget repository (containg a paket.dependencies file) with FSharp.Compiler.Tools installed.
