I believe that I have followed the instructions in the measure writing guide carefully, however when I try to test the create baseline building measure I get the error seen in the console of the attached picture.

image description

If the picture is difficult to read: It reads

ruby "C:\Users\szilasia\Desktop\CreateBaselineBuilding\tests\create_baseline_building_test.rb"
Process started >>>
C:/Ruby23/lib/ruby/2.3.0/rubygems/core_ext/kernel_require.rb:55:in `require': cannot load such file -- openstudio (LoadError)
    from C:/Ruby23/lib/ruby/2.3.0/rubygems/core_ext/kernel_require.rb:55:in `require'
    from C:/Users/szilasia/Desktop/CreateBaselineBuilding/tests/create_baseline_building_test.rb:1:in `<main>'
<<< Process finished. (Exit code 1)

It seems as though Ruby can't load the openstudio module under in the path C:\Program Files\OpenStudio 1.13.0\Ruby. Am I correct?

What could be the cause of this?

Any pointers would be most appreciated I am new to Ruby so probably I am missing something.

It looks like you're using Ruby 2.3. OpenStudio 1.13 is currently compatible with Ruby 2.0 (link).

Try uninstalling 2.3 and installing 2.0 using the Optional - Install Ruby instructions.

@MatthewSteen thanks for your reply, unfortunately it still doesn't work I have the same error, I am just trying to test my code in Notepad++ before I apply it to OpenStudio is this the right approach?

Ruby is installed on C:\Ruby200-x64 and it works fine when not running a OpenStudio script

Did you do these steps:

Create a text file with the following text inside:

require 'C:\Program Files (x86)\OpenStudio 1.7.0\Ruby\openstudio.rb'

Save the file as openstudio.rb here: C:\Ruby200\lib\ruby\site_ruby\openstudio.rb (next to the 2.0.0 folder).

@antonszilasi follow the instructions I linked above to connect OpenStudio with your Ruby install as Andrew mentions above.

I followed your instructions, it still refuses to run however now the error is simply

C:/Users/szilasia/OpenStudio/Measures/Create DOE Prototype Building/measure.rb:3:in `<main>': uninitialized constant OpenStudio (NameError)

My environment variable is Ruby: C:\Program Files (x86)\OpenStudio 1.13.0\ruby-install\ruby\bin

and the text file placed under: C:\Ruby200-x64\lib\ruby\site_ruby which simply says: require 'C:\Program Files (x86)\OpenStudio 1.13.0\Ruby\openstudio.rb'

What else could be going wrong?

Do you have the 32 bit or 64 bit version of OS 1.13.0 installed? If the latter, remove the (x86) from your path.
