<div>Of course, this particular gem library is installed and it perfectly runs in a regular shell, such as zsh or bash.</div><div><br></div><div>But for some reason, it gives an error when executed in Emacs buffer.</div><div>
<br></div><div><div>ruby_twitter.rb:2:in `require&#39;: no such file to load -- twitter (LoadError)</div><div><span class="Apple-tab-span" style="white-space:pre">	</span>from ruby_twitter.rb:2</div></div><div><br></div><div>
Looks like Emacs cannot find the gem library.</div><div><br></div><div>How can I have Emacs find the proper library or gems?</div><div><br></div><div>soichi</div>
