Understanding the $ PATH Variable: Installed Gems Are Not in the Way

Question

Good morning!

I am working on a ruby ​​pearl. So far, the stone has not been transferred to any server - all local development so far.

I would like to test the gem when I build it (using TTD). I ran bundle exe rake buildboth bundle exe rake installto build and install gem in my local environment. Now I expect that when I find gem_nameanywhere in my terminal that it gem_nameneeds to be recognized. Unfortunately, this is not the case; instead, I get this error:

    `$ -bash gem_name: command not found`

The only thing I can do is lead to some problem with my path.

Here is the result of my $ PATH:

    echo $PATH
    /Users/throw/.rvm/gems/ruby-2.2.1/bin:
    /Users/throw/.rvm/gems/ruby-2.2.1@global/bin:
    /Users/throw/.rvm/rubies/ruby-2.2.1/bin:
    /usr/local:/usr/local/bin:
   /usr/local/sbin:/usr/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:
   /usr/local/git/bin:/Users/throw/.rvm/bin:/Users/throw/.nvm/nvm.sh:
  /Users/throw/.node/bin:/Applications/Postgres.app/Contents/9.5.0.0/latest/bin

And here is the output of the command gem env:

    gem env

Answer 1

gemspec:

spec.bindir "exe"
spec.executables ["your_script_name"]

, rubygems /Users/throw/.rvm/gems/ruby-2.2.1/bin, $PATH

EDIT: gemspec git ls-files, , gem gem.
