安装 R 包 pdftools 困难

Question

我正在尝试安装 R 包“pdftools”并遇到以下问题：

In file included from libqpdf/Pl_DCT.cc:1:
include/qpdf/Pl_DCT.hh:27:10: fatal error: 'jpeglib.h' file not found
#include <jpeglib.h>
         ^
1 error generated.
make: *** [libqpdf/Pl_DCT.o] Error 1
ERROR: compilation failed for package ‘qpdf’

我在装有 OS X 10.10.5 的 Mac 上使用 R 版本 3.3.3，由于多种原因，目前无法更新我的操作系统。

1. 我验证下载的源包在： /private/var/folders/t3/_mlp_5z15z9_628n5q00pw_s8d_kfs/T/RtmpnJERsz/downloaded_pa​​ckages

2. 我看到了以下帖子： 'jpeglib.h' file not found

然后跑了

$ find /usr/local -name \*jpeg\* -print -name \*jpg\* -print
/usr/local/Cellar/boost/1.71.0/include/boost/gil/extension/io/jpeg
/usr/local/Cellar/boost/1.71.0/include/boost/gil/extension/io/jpeg.hpp

/usr/local/Homebrew/Library/Taps/homebrew/homebrew-core/Formula/openjpeg.rb
/usr/local/Homebrew/Library/Taps/homebrew/homebrew-core/Formula/recoverjpeg.rb
find: /usr/local/jamf: Permission denied

文件“jpeglib.h”似乎没有列出，但我将它定位在：/anaconda3/pkgs/jpeg-9b-he5867d9_2/include/jpeglib.h

1. 根据其他帖子，我从终端尝试：

$ brew install boost. (Lot of installing, no errors)
$ brew doctor (Lot of installing, no errors)
$ xcode-select: error: command line tools are already installed, use "Software Update" to install updates
$ brew install cairo gobject-introspection pixman (Lot of installing, no errors)

然后重新启动并尝试再次安装 pdftools，结果相同。

4. 也看到了这篇文章，但它完全超出了我的想象： https://www.cocoanetics.com/2012/01/helping-xcode-find-library-headers/

感谢任何简单步骤的解决方案。

我刚刚安装了 pdftools，没有任何问题。升级您的 R 版本可能会解决您的问题。
