uninitialized constant MemFs::Dir::Tmpname (NameError)

[TastyPi]

The following code:

MemFs.activate { Tempfile.create }

produces the following error:

ruby/3.2.0/tempfile.rb:400:in `create': uninitialized constant MemFs::Dir::Tmpname (NameError)
                                                                                                     
  Dir::Tmpname.create(basename, tmpdir, **options) do |tmpname, n, opts|                             
     ^^^^^^^^^  

This is with Ruby 3.2.0 and memfs 1.0.0

It looks like there hasn't been a release since 2017?

I tried with gem "memfs", github: "simonc/memfs" but the error still occurs.

It looks like not the whole File/FileUtils API is covered.
