I am following this tutorial (Hosting Nancy with Nginx on Ubuntu) with one change. I am using the Spark view engine instead of the built in view engine.
Spark view engine throws an error building any view when the Nancy host is running under supervisor.

If I run the environment setting script /opt/mono/env.sh and then run my host from the command prompt, the website works.
I think it must be due to my Nancy host not being able to find Mono when running under supervisor.
For reference:
#env.sh
export PATH=/opt/mono/bin:$PATH
export LD_LIBRARY_PATH=/opt/mono/lib:$LD_LIBRARY_PATH
export PKG_CONFIG_PATH=/opt/mono/lib/pkgconfig:$PKG_CONFIG_PATH
I am using Mono 3.8.0 from here: http://download.opensuse.org/repositories/home:/tpokorra:/mono/xUbuntu_14.04/
How do I set these paths so that Nancy host can find Mono when running under supervisor?
I needed to set the environment option in my supervisor configuration file.
Here is the setting that worked for the above example.
environment=PATH="/opt/mono/bin:$PATH"
