rails-latex can't find pdflatex

Question

I'm using Rails 4.1.4 with rails-latex gem to generate PDFs, but I got this error when viewing the PDF:

pdflatex failed: See /home/sarunint/dockey/tmp/rails-latex/3639-548202856440663759/input.log for details

And this is the content of the log file:

No such file or directory - pdflatex:

...much more...

I'm pretty sure that the latex is installed on my system. Can someone help me?

确保目录/usr/local/texlive/2014/bin/x86_64-linux位于$PATH ，或者位于rails-latex用于检测程序位置的任何设置中。
