将Poppler添加到Debian中的Path [英] Add Poppler to Path in Debian

问题描述

我刚刚使用以下命令在我的debian服务器上安装了poppler:

I have just installed poppler on my debian server using the command:

sudo apt-get install poppler-utils

sudo apt-get install poppler-utils

但是，当我执行命令时:

However, when I execute the command:

pdftocairo-帮助

pdftocairo --help

找不到该函数，因此我假设此程序尚未自动链接到我的PATH变量中.我的问题是我对Linux不太熟悉，也不知道如何找出poppler的安装位置，也不知道如何从现有的PATH位置创建指向Poppler的链接文件.

The function cannot be found, so I assume this program has not automatically linked into my PATH variable. My issue is that I am not very experienced with Linux and I don't know how to find out where poppler installed, nor how to create a link file to Poppler from an existing included PATH location.

任何帮助将不胜感激，尤其是如果有人可以解释我如何知道这些程序将自己安装在何处.

Any help would be appreciated, especially if someone can explain how I know where these programs are installing themselves.

推荐答案

您不需要对PATH做任何事情-这是维护人员的任务，使所有事情都按预期进行".

you should not need to do anything with the PATH - it's the maintainer's task to make everything work "as expected".

您的问题可能有几个原因:

your problem could have several reasons:

• 您的poppler-utils版本不带有pdftocairo二进制文件
• 您的poppler-utils版本将pdftocairo插入到不在PATH
中的路径中
• 您(或其他人)已经将PATH弄乱了，因此它不包含poppler-utils将二进制文件安装到的目录.

• your version of poppler-utils does not come with the pdftocairo binary
• your version of poppler-utils insatlls pdftocairo into a path that is not in your PATH
• you (or somebody else) have messed with the PATH, so it doesn't contain the directory where poppler-utils installed the binaries to any more.

，因此首先检查poppler-utils是否安装文件(以及安装位置). 以下将为您提供该软件包安装的所有文件的列表:

so first check whether poppler-utils installs the file (and where to). the following will give you a list of all files installed by the package:

$ dpkg -L poppler-utils
[...]
/usr/bin/pdftops
/usr/bin/pdftocairo
/usr/bin/pdftohtml
[...]

如您所见，

在我的系统上-已安装poppler-utils 0.18.4-6-程序包将pdftocairo安装到/usr/bin中，这是所有应用程序的 default 路径，并且应该已经进入您的路径.

as you can see, on my system - which has poppler-utils 0.18.4-6 installed - the package installed a pdftocairo into /usr/bin which is the default path for all applications, and which should already be in your PATH.

要检查您的PATH变量，请执行类似的操作

to check your PATH variable do something like

$ echo $PATH
/usr/local/bin:/usr/bin:/bin:/usr/bin/X11:/usr/games

如您所见，

我的PATH包含/usr/bin，实际上我可以做到:

as you can see, my PATH contains /usr/bin, and indeed i can do:

$ pdftocairo --help
pdftocairo version 0.18.4
Copyright 2005-2011 The Poppler Developers - http://poppler.freedesktop.org
Copyright 1996-2004 Glyph & Cog, LLC
[...]

如果您的PATH不包含/usr/bin，则说明您的系统存在严重问题(例如，您尝试更改路径并意外删除了所有先前的设置).

if your PATH does not contain /usr/bin, then something is seriously wrong with your system (for instance, you have tried changing your path and accidentally removed all the previous settings).

在任何情况下，向PATH添加新路径都是非常简单的.所有路径都用冒号分隔，因此您应该执行以下操作:

in any case, adding a new path to PATH is quite simple; all paths are separated by colons, so you should do something like the following:

$ export PATH=/path/to/my/bin:${PATH}

这将在搜索路径的开头添加/path/to/my/bin/，因此现在将首先在/path/to/my/bin/中搜索所有二进制文件，然后在/usr/local/bin中搜索，等等.

this will add /path/to/my/bin/ at the beginning of the search-path, so all binaries will now be searched first in /path/to/my/bin/ and then /usr/local/bin and so forth.
