console - Gem not available in self executing ruby file -

-

i have written myself simple ruby script requires listen gem. running in console works perfectly.

$ ruby script.rb args

i passing pwd argument. got annoyed of wanted make script executable across linux. added following line beginning of script

#!/usr/bin/env ruby  require "listen" ...

when use self executing file, runs error.

$ ./script.rb

output:

./listen.rb:55: uninitialized constant listen (nameerror)     ./script.rb:3:in `require'     ./script.rb:3

do have suggestions cause of problem be? have 1 guess: #!/usr/bin/env ruby calls different ruby env $ ruby is. how can find out? (i using rbenv manage rubys)
