LaTeX：無法創建文檔

Question

我剛開始使用LaTeX，並試圖創建我的第一個文檔。我正在使用Mac OS X 10.8.3。

在創建hello.tex文件後，我在命令行中鍵入latex hello。這將返回以下輸出：

This is pdfTeX, Version 3.1415926-2.4-1.40.13 (TeX Live 2012)

! LaTeX Error: File `(.cls' not found. 

Type X to quit or <RETURN> to proceed,

我一直在試圖爲此找到解決方法，但一直無法這樣做。任何幫助將不勝感激。

Answer 1

在聲明文檔的類時，最有可能使用了括號而不是大括號。也就是說，你有類似

\documentclass(article) 

，但它應該是

\documentclass{article} 

順便說一句，你真的還需要包括文件的內容，而不僅僅是錯誤消息。
