There are instructions for a manual install. They’re not too bad if you already have node:
git clone --depth=1 --branch v5.1.22 https://github.com/Jermolene/TiddlyWiki5.git
git clone --depth=1 https://github.com/OokTech/TW5-Bob.git TiddlyWiki5/plugins/OokTech/Bob
cp -r TiddlyWiki5/plugins/OokTech/Bob/MultiUserWiki TiddlyWiki5/Wikis/BobWiki/
After that is finished, and to start up tiddlywiki later type:
node ./tiddlywiki.js Wikis/BobWiki --wsserver
I changed 5.1.22 to 5.2.0. I had to add symlinks to titlecase versions of editions, plugins, and themes. I imagine you wouldn’t need to do that on Windows.
It seems to run, and I was able to create wikis that say “5.2.0”. Unfortunately, as I have found in the past, Bob wouldn’t acknowledge my existing node TW files. It was happy as long as it was using it’s own local wiki directory. Since I don’t use Bob, except for testing, I don’t know if anything else is broken.
