我正在尝试在我的 Ubuntu 18.04.1 LTS 中安装 pandoc 2.3.1。
首先，我删除所有旧的 pandoc 版本（我的情况是 pandoc 1.19.2.1）
manolo@manolo:~$ sudo apt-get remove pandoc
Reading package lists... Done

Reading state information... Done
Package 'pandoc' is not installed, so not removed
0 upgraded, 0 newly installed, 0 to remove and 39 not upgraded.
manolo@manolo:~$ sudo apt-get remove --auto-remove pandoc

Package 'pandoc' is not installed, so not removed
0 upgraded, 0 newly installed, 0 to remove and 39 not upgraded.
manolo@manolo:~$ sudo apt-get purge pandoc
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package 'pandoc' is not installed, so not removed
0 upgraded, 0 newly installed, 0 to remove and 39 not upgraded.
然后，我运行以下命令来检查 pandoc 版本，由于未安装 pandoc，因此应该给我一个空白结果。但是，我得到了以下结果：
manolo@manolo:~$ pandoc -v
pandoc 1.19.2.1
Compiled with pandoc-types 1.17.0.4, texmath 0.9, skylighting 0.1.1.4

然后，我尝试安装最新版本的 pandoc：
manolo@manolo:~$ sudo dpkg -i /home/atai/Desktop/pandoc-2.3.1-1-amd64.deb
Selecting previously unselected package pandoc.

虽然，当我检查 pandoc 版本时，我仍然安装有 1.19.2.1：
manolo@manolo:~$ pandoc -v
pandoc 1.19.2.1
Compiled with pandoc-types 1.17.0.4, texmath 0.9, skylighting 0.1.1.4

我的猜测与 pandoc 的安装路径有关。
manolo@manolo:~$ whereis pandoc
pandoc: /usr/bin/pandoc /home/atai/anaconda3/bin/pandoc /usr/share/man/man1/pandoc.1.gz
manolo@manolo:~$ type pandoc
pandoc is hashed (/home/atai/anaconda3/bin/pandoc)

我遇到了同样的问题，更新所有 conda 包后问题得到解决：conda update --all
