There is NoMethodError `encode': undefined method `force_encoding' while running through terminal

[CuriousNikhil]

The terminal error logs are:

/var/lib/gems/1.8/gems/osc-ruby-1.1.1/lib/osc-ruby/osc_types.rb:21:in encode': undefined method force_encoding' for "/run-code\000\000\000":String (NoMethodError)

I think this is an error from Sonic Pi because you used run-code instead of run_code (See the syntax in the Help File Lang section for Sonic Pi)

[CuriousNikhil]

No sir. I'm just using sonic-pi-cli and i am just placing this command sonic_pi play 50 in the terminal. My terminal window is showing the above error.

OK: sorry. What platform are you running on? what version of Sonic Pi? What version of ruby do you have installed?
what does gem list give as output? does it show osc-ruby (xxx)

[CuriousNikhil]

I am running sonic-pi on RaspberryPi with latest version of 2.10
the output of gem-list is:

*** LOCAL GEMS ***

osc-ruby (1.1.1)
sonic-pi-cli (0.1.1)

Am I right in thinking that you're running a relatively old version of Ruby (1.8)? Would you be able to try again with a newer version?
