我一直在试图用RStudio的“Knit PDF”功能来制作一个简单的PDF。R knitr生成pdf时出错41（windows）
每次我试图将样本文档转换为PDF我得到以下信息：
|............. | 20%
ordinary text without R code
|.......................... | 40%
label: unnamed-chunk-1
|....................................... | 60%
ordinary text without R code

Execution halted
No TeX installation detected (TeX is required to create PDF output). You should install a recommended TeX distribution for your platform:
Windows: MiKTeX (Complete) - http://miktex.org/2.9/setup (NOTE: Be sure to download the Complete rather than Basic installation)
Mac OS X: TexLive 2013 (Full) - http://tug.org/mactex/ (NOTE: Download with Safari rather than Chrome strongly recommended)
Linux: Use system package manager
我编辑了我的电脑上的路径位置以及PDF的所要的标题（改变他们在适当的地方使用“PATH1”，“PATH2”和“DOCTITLE”。）
我已经使用该链接多次下载MikTex到多个位置，我曾尝试使用ProTex，因为其他一些成功的做法。我曾尝试将MikTex的bin添加到环境中，但无论如何，似乎R无法找到Tex。大多数可用的建议都是针对OSX的，并且我已尝试将这些解决方案适用于Windows，但无济于事。
请打开'cmd.exe'并输入'pdflatex'。你看到'This is pdfTeX ...'还是错误信息？ –
您是否安装了MikTex，完成版本？ 32位：http://mirrors.ctan.org/systems/win32/miktex/setup/setup-2.9.5870.exe 64位：http://mirrors.ctan.org/systems/win32/miktex/setup/setup-2.9 .5870-x64.exe然后重新启动R-studio – NangSaigon
CL，当我输入pdflatex时，我得到的回应是：'This is pdfTex，Version 3.14159265-2.6-1.40.16' –
