I am trying to setup LaTeX Workshop Extension for Visual Studio Code. I have The MacTeX-2018 Distribution that I installed using Homebrew cask. I cannot setup formatting. Errors lead me to the answer for the GitHub LaTeX-Workshop issue. First three commands worked just well for me:

sudo cpan Unicode::GCString
sudo cpan App::cpanminus
sudo cpan YAML::Tiny

Unfortunately, trying to execute the last one (I also tried sudo perl -MCPAN -e 'install "File::HomeDir"' gives and error and one unsatisfied dependency:

I also tried to install the mentioned unsatisfied dependency. Again, I faced the following error trying to install Mac::SystemDirectory module using cpan:

My OS is MacOS Mojave 10.14.
I have xCode version 10.1 installed.
I have make installed:

Vitaliis-MacBook-Pro:~ vitalii$ make -v

This program built for i386-apple-darwin11.3.0

I also have clang compiler

Vitaliis-MacBook-Pro:~ vitalii$ cc -v
Apple LLVM version 10.0.0 (clang-1000.10.44.2)
Target: x86_64-apple-darwin18.0.0
Thread model: posix
InstalledDir: /Library/Developer/CommandLineTools/usr/bin

As I head some problems after updating to Mojave (could not use git), I already followed instructions in the answer for this post.
Could you help me with that?

I had the exact same problem and found a workaround:

  1. Install the current version of Perl using Homebrew: brew install perl
  2. Check if xcode-select -p points to the Command Line Tools. If not, run xcode-select --switch /Library/Developer/CommandLineTools
  3. Install Mac::SystemDirectory using cpan (not cpanm): cpan Mac::SystemDirectory

I have no experience with Perl and I have no idea why this worked, but it did :)
