使用 texlive，为什么我可以将 knitr Rnw 文件从 R 编译为 pdf，但不能将 knit R 的 tex 输出编译为 pdf

Question

knitr 编译并生成 pdf 文件，但由 knitr 生成的 tex 文件无法编译（使用 livetex）

这里是 test.Rnw

\documentclass[letter]{article}
\title{y}
\author{z}
\begin{document}
\maketitle
<<assignment, echo = TRUE>>=
(X <- 10)
@
\end{document}

以下生成pdf文件：texi2pdf(file = "test.tex", clean = TRUE)

knitr产生的reamble有问题：

  \usepackage{framed}
\makeatletter
\newenvironment{kframe}{%
 \def\at@end@of@kframe{}%
 \ifinner\ifhmode%
  \def\at@end@of@kframe{\end{minipage}}%
  \begin{minipage}{\columnwidth}%
 \fi\fi%
 \def\FrameCommand##1{\hskip\@totalleftmargin \hskip-\fboxsep
 \colorbox{shadecolor}{##1}\hskip-\fboxsep
     % There is no \\@totalrightmargin, so:
     \hskip-\linewidth \hskip-\@totalleftmargin \hskip\columnwidth}%
 \MakeFramed {\advance\hsize-\width
   \@totalleftmargin\z@ \linewidth\hsize
   \@setminipage}}%
 {\par\unskip\endMakeFramed%
 \at@end@of@kframe}
\makeatother

以下是错误：

    \begin{minipage} does not have matching end; at least one unbalanced
 begin-end  test.tex    /tests-R    line 39 Problem

\end{minipage} found with no preceding \begin   test.tex    /tests-R    line 38

出于显而易见的原因，至少有一个出版商想要 tex 文档，而不是 Rnw 文档

我也遇到过这个问题，不过好像是路径问题。如果yourfile.Rnw 位于带有空格的路径上，knit2pdf 将抛出错误，您可以在texput.log 中清楚地看到它，而不是在错误消息中的yourfile.log 中。但是，如果您手动编译yourfile.tex，一切似乎都很好。

也许@Yihui 可以解释为什么会这样。

编辑这是输出日志：

knit2pdf("test.Rnw")

我也没有收到错误。使用 RStudio 中的“编译 PDF”按钮，该按钮创建了以下 *.tex 文件，我可以使用 TexMaker 进行编译：

\documentclass[letter]{article}

\usepackage[]{color}

%% otherwise use linewidth (to make sure the graphics do not exceed the margin)

\linewidth
\else
\Gin@nat@width
\fi
}
\makeatother
