title: Installed Module not contained in the Perl's @INC path
body: <p>I have an issue on including the Excel-Writer-XLSX module in the @INC path. I did some research before posting this question and tried several solutions, but they all failed. <br><br>
  So I did </p>
  
  <pre><code>$sudo perl -MCPAN -e 'install Excel::Writer::XLSX'
  </code></pre>
  
  <p>But after I run the code, I got this message </p>
  
  <pre><code>--can't locate Excel/Writer/XLSX.pm in @INC(you may need to install the Excel::Writer::XLSX module) (@INC contains: /Library/Perl/5.18/darwin-thread-multi-2level/...)
  </code></pre>
  
  <p>This is not a duplicate question, because the Excel::Writer::XLSX module has been successfully installed in my computer and I don't need to install it again. The thing is when I checked my library folder, the perl5 folder is not there, as it was suggested by the @INC path. Instead, Perl5 folder is in my user folder...and actually the module can be found in the lib folder inside the perl5 folder<br><br>
  I'm not quite sure what is happening...Why the @INC path shows the perl/5.18 is inside the library folder? If you know how to solve this issue, please advice. Thank you so much! </p>
