[Tex/LaTex] Can’t locate Algorithm/Diff.pm in @INC (you may need to install the Algorithm::Diff module)

latexdiffmiktexperl

I'm having the same problem as described in the closed question "https://tex.stackexchange.com/questions/104350/problem-regarding-latexdiff-perl-and-miktex-2-9-on-win7".

Following the solution does not work in my case. However, the error message now includes the path I added (see below).

I've installed latexdiff via MikTeX 2.9 console on Win10. Originally tried with ActivePerl, then uninstalled and installed Strawberry Perl. Issue persists.

$ latexdiff

Install the Algorithm::Diff package from Perl's CPAN package repository. You can do this by running the following command.

perl -MCPAN -e "install Algorithm::Diff"

UPDATE:

Log4perl is definitely no longer required. See comments.

For others running into the same issue but on a Mac:

Install perl via brew:

brew install perl

Use cpan to install the necessary perl packages:

Open cpan and select yes if necessary to setup the config automatically:

cpan

Then install any packages mentioned in your error logs, you may need to install and retry several times to figure out all of the packages you need.

In my case these packages fixed the error messages:

install Log::Log4perl
install Log::Dispatch::File
install YAML::Tiny
install File::HomeDir

Catalina Update

If the installation fails with an error message that sounds like a permissions issue, that may be due to security changes in Catalina. In that case, try forcing the installation:

cpan -fi \
  Log::Log4perl \
  Log::Dispatch::File \
  YAML::Tiny \
  File::HomeDir \
  Unicode::GCString
