我刚刚构建了一个桌面，但似乎在运行 LaTeX 时遇到了问题。
重要信息：
- Windows 7（64 位）
- 华硕 Radeon R9 290
- 所有与 LaTeX 相关的软件都保存在非操作系统驱动器上
- 已经安装并测试了几种不同的编辑器（MikTex、LyX、TeXstudio 和 TeXworks），但似乎都无法编译/构建任何东西 - 重新安装了几个作为测试
- 似乎没有创建日志文件
作为测试代码，我一直使用从互联网上复制的一个基本示例，以防它是软件包问题，以及我写的一封求职信，因为我可以保证它能正常工作（尽管它确实需要一些软件包）。对这里可能是什么问题有什么想法吗？谢谢帮助！

基本测试代码：
\documentclass[12pt]{article}
% options include 12pt or 11pt or 10pt
% classes include article, report, book, letter, thesis
\title{This is the title}
\author{Author One \\ Author Two}
\date{29 February 2004}
\begin{document}
\maketitle
This is the content of this document.
This is the 2nd paragraph.
Here is an inline formula:
$ V = \frac{4 \pi r^3}{3} $.
And appearing immediately below
is a displayed formula:
$$ V = \frac{4 \pi r^3}{3} $$

硬盘识别确认：
答案1
我找到了问题所在。我有一个旧硬盘，上面安装了某个版本的 LaTeX，所以当编译器运行时，它会从旧副本中调用包，从而导致某种无限循环。从硬盘中删除所有 LaTeX 文件，并在新硬盘上进行清除安装，所有问题都解决了。事后看来，我应该立即这样做，但我认为 LaTeX 不会对包进行全局搜索，而只会在关联的本地文件夹中查找。
