在CentOS上发布Python3.6中的pdftotext安装问题
在CentOS上发布Python3.6中的pdftotext安装问题
提问于 2019-03-08 01:57:06
我在Python3.6(Anaconda5.1.0)中安装pdftotext时遇到了一些问题。
先做一些简短的说明：
- 我在VirtualBox上使用了VirtualBox 6.7
- 我知道它可以工作，因为我的it组已经在我们的服务器上安装了它。注意:我发现我们的服务器确实安装了C++包装器，我正在试图弄清楚它是如何得到的。
- 我正试图让一个现有的应用程序开始工作，所以此时我不想寻找一个替代
pdftotext库的方法。
我按照github回购公司的指示，已经尝试了这个步骤：
费多拉、红帽和朋友：
sudo yum install gcc-c++ pkgconfig poppler-cpp-devel python-devel redhat-rpm-config但问题似乎围绕着波普尔-cpp的发展。我看不出yum search poppler里面有那个包裹

我找到了解决办法。通过遵循从这个链接安装libpoppler-cpp的说明，我成功地安装了pdftotext。
按照这个回购的指示
On CentOS 在CentOS上，
libpoppler-cpp库不包含在系统中，因此我们需要从源代码构建。请注意，C++11的最新版本需要在CentOS上不可用的libpoppler.Build，因此我们构建了一个稍微老一点的版本，即libpoppler.Build依赖项安装wget openjpeg2 devel openjpeg2 2-devel#下载和解压wget https://poppler.freedesktop.org/poppler-0.47.0.tar.xz tar -Jxvf Pop烧录-0.47.0.tar.xz cd Pop烧录-0.47.0# Build并安装。/configure默认情况下安装在/usr/local/lib和/usr/local/include中。在CentOS上，这不是默认的搜索路径，因此我们需要将PKG_CONFIG_PATH和LD_LIBRARY_PATH设置为将R指向正确的目录： 导出LD_LIBRARY_PATH="/usr/local/lib“导出PKG_CONFIG_PATH=/usr/local/lib/pkgconfig”

pdftotext应该在poppler-utils，中，所以请尝试yum install poppler-utils
编辑： Hmm。EPEL存储库中有一个名为CentOS 6的包，称为pypoppler，它将自己描述为“Poppler呈现库的呈现库”。我没有看到任何迹象表明它包括poppler/cpp/{ can }，但您可以尝试一下。(您可能需要先安装pycairo。)
否则，您可能会尝试安装pdftotext的早期版本 (例如pip install pdftotext==1.0.0)，以找到一个与CentOS 6兼容的版本。不过，最早的版本出现在2017年6月，所以这可能没有帮助。
我不认为你有兴趣升级到CentOS 7？

实际上有一个正确的CentOS 7包。仅仅安装poppler软件包是不够的，因为它不包括所需的CPP头文件，您只需要安装poppler和软件包：
百胜安装波普尔-cpp波普尔-cpp-开发
之后，您可以在不需要自定义编译和设置环境路径变量的情况下安装pdftotext包。
