Hi,

The documentation claims that TinyTeX is portable, but that doesn't seem to be the case.

On Linux, it can be reproduced like this.

1. Install TinyTeX"

wget -qO- "https://yihui.name/gh/tinytex/tools/install-unx.sh" | sh

2. Find all occurrences of the user's home directory

grep -R --exclude="*.log" ${HOME} .TinyTeX/

In a portable installation, you would expect that there are no hardcoded paths. Yet, there are:

Of which these are probably relevant:

3. Pack .TinyTeX

tar czf /tmp/tinytex.tar.gz .TinyTeX

4. As another user, unpack .TinyTeX

tar xzf /tmp/tinytex.tar.gz

5. Execute tlmgr path add

.TinyTeX/bin/x86_64-linux/tlmgr path add

Which results in:

Can't locate TeXLive/TLConfig.pm in @INC (you may need to install the TeXLive::TLConfig module) (@INC contains: /.TinyTeX/texmf-dist/scripts/texlive /.TinyTeX/tlpkg /etc/perl /usr/local/lib/x86_64-linux-gnu/perl/5.26.1 /usr/local/share/perl/5.26.1 /usr/lib/x86_64-linux-gnu/perl5/5.26 /usr/share/perl5 /usr/lib/x86_64-linux-gnu/perl/5.26 /usr/share/perl/5.26 /usr/local/lib/site_perl /usr/lib/x86_64-linux-gnu/perl-base) at .TinyTeX/bin/x86_64-linux/tlmgr line 100.
BEGIN failed--compilation aborted at .TinyTeX/bin/x86_64-linux/tlmgr line 100.

6. Test TinyTeX

mkdir -p rpackages
echo ".libPaths('~/rpackages')" > .Rprofile
R --silent -e 'install.packages("tinytex")'
R --silent -e 'tinytex::tinytex_root()'

Results in:

> tinytex::tinytex_root()
[1] ""

Session Info
