How to install only cmap.sty required packages in my machine

Question

I'm trying to convert a tex document to pdf.

But when I did pdflatex doc.tex , I got

This is pdfTeX, Version 3.14159265-2.6-1.40.16 (TeX Live 2015/Debian) (preloaded format=pdflatex)
 restricted \write18 enabled.
entering extended mode
(./doc.tex
LaTeX2e <2016/02/01>
Babel <3.9q> and hyphenation patterns for 3 language(s) loaded.
(/usr/share/texlive/texmf-dist/tex/latex/base/article.cls
Document Class: article 2014/09/29 v1.4h Standard LaTeX document class
(/usr/share/texlive/texmf-dist/tex/latex/base/size10.clo))

! LaTeX Error: File `cmap.sty' not found.

Type X to quit or <RETURN> to proceed,
or enter new name. (Default extension: sty)

Enter file name: X

From here I got to know that I need to do apt-get install texlive-fonts-recommended texlive-latex-recommended texlive-latex-extra . But this says it will download 656 MB of archive.

Due lack of space in my ubuntu partition, Is there a way to install only required packages for cmap.sty

Answer 1

在 Ubuntu 18.04 上， apt install texlive-latex-extra工作。

Answer 2

If your native texlive distribution is properly configured you should be able to install a package with tlmgr

tlmgr install cmap

should be enough to install the cmap package and its dependencies. Let us know how much space do you save...
