在Texstudio的Latex中创建PDF时出错

Question

我想在乳胶中创建演示文稿。以下是代码：

\documentclass{beamer} 
\usetheme{default} 

\title{Electrical Machines} 
\subtitle{Electromechanical Energy Conversion} 
\author{Vivek kumar Pal} 
\institute{Department of Electrical Engineering\\VJTI} 
\date{\today} 

\subject{Electricals} 

\begin{document} 
\end{document} 

代码得到正确执行。但是下面的错误是要创建PDF格式：

does not look like a valid PDF document. Either the file is corrupt or it is in the process of creation. Retrying every two seconds. 

请在此帮助，让我们知道原因。

Answer 1

您缺少内容。一旦你添加它会正常工作。

\documentclass{beamer} 
\usetheme{default} 

\title{Electrical Machines} 
\subtitle{Electromechanical Energy Conversion} 
\author{Vivek kumar Pal} 
\institute{Department of Electrical Engineering\\VJTI} 
\date{\today} 

\subject{Electricals} 

\begin{document} 
Enter content here. 
\end{document}
