Symlinked CLI cannot find EnergyPlus on Mac

[nmerket]

I am trying to use the OpenStudio CLI and it complains of not being able to find EnergyPlus unless I set the ENEREYPLUS_EXE_PATH environment variable. This only happens when I use the CLI that is symlinked into /usr/local/bin/openstudio. When I use the one in /Applications/OpenStudio-2.1.0/bin/openstudio it is able to find EnergyPlus just fine.

If I run the following ruby script using the CLI (test.rb).

puts "ENERGYPLUS_EXE_PATH = '#{ENV['ENERGYPLUS_EXE_PATH']}'"
ENV['ENERGYPLUS_EXE_PATH'] = nil
puts "ENERGYPLUS_EXE_PATH = '#{ENV['ENERGYPLUS_EXE_PATH']}'"
puts OpenStudio::openStudioLongVersion
puts OpenStudio::getOpenStudioModule
puts OpenStudio::getOpenStudioModuleDirectory
puts OpenStudio::getEnergyPlusExecutable
puts OpenStudio::getEnergyPlusDirectory

From the symlinked cli openstudio execute_ruby_script test.rb

ENERGYPLUS_EXE_PATH = '/Applications/OpenStudio-2.1.0/EnergyPlus/energyplus-8.7.0'
ENERGYPLUS_EXE_PATH = ''
2.1.0.fae436fc10
/usr/local/bin/openstudio
/usr/local/bin

From the full-path cli /Applications/OpenStudio-2.1.0/bin/openstudio execute_ruby_script test.rb

ENERGYPLUS_EXE_PATH = '/Applications/OpenStudio-2.1.0/EnergyPlus/energyplus-8.7.0'
ENERGYPLUS_EXE_PATH = ''
2.1.0.fae436fc10
/Applications/OpenStudio-2.1.0/bin/openstudio
/Applications/OpenStudio-2.1.0/bin
/Applications/OpenStudio-2.1.0/bin/../EnergyPlus/energyplus
/Applications/OpenStudio-2.1.0/bin/../EnergyPlus

In the CLI Doc there is a section about "Environment Variables", reading it I have added this to my ~/.bash_profile:

export RUBYLIB=/Applications/OpenStudio-2.2.0/Ruby
export ENERGYPLUS_EXE_PATH=/Applications/OpenStudio-2.2.0/EnergyPlus/energyplus-8.7.0

Isn't that enough?

Then again, it shouldn't be to hard to check if it's a symlink and follow that. I think that the problem is moduleIsRunningFromBuildDirectory which doesn't follow the symlink.

This is perhaps related to #2616 too.

Confirmed that Kyle's fix in 8524738 works:

Ran user script with 2.6.0:

ENERGYPLUS_EXE_PATH = ''
2.6.0.8c81faf8bc
/Applications/OpenStudio-2.6.0/bin/openstudio
/Applications/OpenStudio-2.6.0/bin
/Applications/OpenStudio-2.6.0/bin/../EnergyPlus/energyplus
/Applications/OpenStudio-2.6.0/bin/../EnergyPlus
