Building Julia Offline

I ran into the same problem on julia 0.7. The workaround in that case was to

  1. build julia 0.7 on some other machine (with access to the internet)
  2. copy the _build directory to the non-networked machine,
  3. run touch doc/_build/html/en/index.html.
  4. run make install

This tricked make install into thinking the documentation was already up-to-date, so it doesn’t try to rebuild it, and therefore downloading packages.
