latex - pdflatex: \includegraphics{} -> 文件未找到
问题描述
首先：我知道这个问题已经出现了成百上千次。但是我在过去四个小时内找到的给定答案都没有解决我的具体问题，我在这里变得疯狂。我将非常感谢任何帮助和建议！
试图编译一个非常简单的 .tex 文件，包括一个\includegraphics命令，我最终得到一个“找不到文件”错误。以以下作为一个非常简约的例子：
\documentclass{report}
\usepackage{graphicx}
\begin{document}
\includegraphics{b}
\end{document}
图像文件实际上只是称为“b.jpg”（同时），它肯定与 tex 文件位于同一路径中。在命令中添加“.jpg”不会改变任何事情。也没有调用graphics而不是graphicsx。
创建的输出文件包含以下内容：

为什么它以“这是 pdfTeX”开头，即使我明确选择了pdflatex？这可能是这里的关键吗？我在 TeXnicCenter 2.02 中使用 pdflatex，在 Win10 64 位中使用 MikTex 2.9。已经尝试重新安装 MikTex。
提前感谢您的帮助，非常感谢！
