The truth may hurt for a little while but a lie hurts forever.
真相可能会使我们痛一时，但谎言会令我们痛一生。
Ubuntu16.04中使用texlive+texstudio搭建Latex环境
- 1.安装texlive
sudo apt install texlive- 2.安装中文字体包
sudo apt install latex-cjk-all- 3.安装texstudio
sudo apt install texstudio解决texstudio使用过程中遇到的问题：
1.GB.cpx乱码问题
在/usr/share/texmf/tex/latex/CJK/GB/下查找到GB.cpx文件并且使用一下代码替换：
% This is the file GB.cap of the CJK package
% for using Asian logographs (Chinese/Japanese/Korean) with LaTeX2e
%
% created by aloft <aloft@ctex.org> for Standard LaTeX document class.

\endinput2.编译后Pdf中文不显示问题
当使用CJK中文包时，在Texstudio配置中使用pdflatex编译器而不是xelatex编译器。
如果使用ctex中文包时可以使用xelatex编译器。
