如果只想将.tex文件转换为PDF，则不需要pandoc，***直接使用LaTeX处理器(而不是使用pandoc，它将依次调用pdflatex，但只会传递所有LaTeX命令的一个子集):

If you just want to convert a .tex file to PDF you don't need pandoc, it's better to use a LaTeX processor directly (instead of using pandoc which will call pdflatex in turn, but will pass along only a subset of all LaTeX commands):

pdflatex test.tex

要从markdown创建 PDF ，pandoc是正确的工具.默认情况下，它也会在后台使用LaTeX:

To create a PDF from markdown, pandoc is the right tool. It also uses LaTeX under the hood by default:

pandoc test.md -o test.pdf
