使用texlive，爲什麼我可以將knitr Rnw文件編譯爲pdf而不是從編織R輸出到pdf

Question

knitr編譯並生成pdf文件，但由knitr生成的tex文件不能編譯（使用livetex）

這裏是test.Rnw

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

下產生pdf文件：texi2pdf(file = "test.tex", clean = TRUE)

由knitr產生的reamble有一個問題：

\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 

下面是錯誤：

\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 

出於顯而易見的原因，至少有一個出版商希望TEX文件，而不是RNW文件

我還沒有收到一個錯誤。使用從RStudio「編譯PDF」按鈕，創建以下* .tex文件，我可以編譯使用TexMaker：

\documentclass[letter]{article} 
\usepackage[]{graphicx} 
\usepackage[]{color} 
%% maxwidth is the original width if it is less than linewidth 
%% otherwise use linewidth (to make sure the graphics do not exceed the margin) 
\makeatletter 
\def\maxwidth{ % 
\ifdim\Gin@nat@width>\linewidth 
\linewidth 
\else 
\Gin@nat@width 
\fi 
} 
\makeatother

我有這個問題太，但它似乎是一個路徑問題。如果yourfile.Rnw位於具有空格的路徑上，則knit2pdf將引發錯誤，並且您可以在texput.log而不是yourfile.log中看到錯誤消息。但是，如果您手動編譯yourfile.tex，則一切似乎都可以。

也許@Yihui可以說明爲什麼這可能是這種情況。

編輯這裏有一個日誌輸出：

knit2pdf("test.Rnw")

$ echo: logi TRUE 

    |.................................................................| 100%

output file: test.tex

test.log不會在工作目錄中存在; texput.log確實包含此消息：
