Since I am new to Ruby, could I ask on how could I add my project vendor di= rectory to the load path ? I did a ruby -e 'puts $LOADPATH' command , and it gave me my current LOAD_P= ATH /usr/local/lib/site_ruby/2.3.0 /usr/local/lib/x86_64-linux-gnu/site_ruby /usr/local/lib/site_ruby /usr/lib/ruby/vendor_ruby/2.3.0 /usr/lib/x86_64-linux-gnu/ruby/vendor_ruby/2.3.0 /usr/lib/ruby/vendor_ruby /usr/lib/ruby/2.3.0 /usr/lib/x86_64-linux-gnu/ruby/2.3.0 I am still googling for a Ruby command that I could use to add my vendor fo= lder to the LOAD_PATH.

You are using require while dynamica= lly generating the path based on the location of test.rb, which could chang= e with respect to your vendor directory. Your error message would seem to indicate that the relative path of kinetic= -sdk.rb from test.rb is not what you are specifying. If you want to use kinetic-sdk.rb as a library file, then the folder you wa= nt to load it from should be in your load path. There are a couple ways to do this but in my opinion the easiest to test wi= th is using "ruby -I" So if I were you, I would keep kinetic-sdk.rb where it is, and add your pro= jects vendor directory to the load path, and then call require in test.rb w= ith that relative path. test.rb would be something like #!/usr/bin/ruby puts "Hello World!" require 'kinectic-sdk-rb/kinectic-sdk.rb' And you would run it with a command like ruby -I my_project/vendor test.rb You can persist that sort of thing by setting your RUBYLIB env variable, or= changing load_path inside your test.rb, etc. There are many ways. -Raj On Wed, Nov 6, 2019 at 1:39 PM Tran, Minh <[email protected]<ma= ilto:[email protected]>> wrote: Hello, I have a scenario that I need to execute a program from the other direc= tory than my current directory.
