rails-latex找不到pdflatex

Question

我正在将Rails 4.1.4与rails-latex gem一起使用来生成PDF，但是在查看PDF时出现此错误：

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

这是日志文件的内容：

No such file or directory - pdflatex:

我很确定乳胶已安装在我的系统上。 有人能帮我吗？

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。
