npm install TiddlyWiki failed

[Charles Palmer]

I did:

$ npm install -g 5pm
$ npm install -g tiddlywiki
/usr/local/bin/tiddlywiki -> /usr/local/lib/node_modules/tiddlywiki/tiddlywiki.js
+ tiddlywiki@5.1.22
updated 1 package in 2.627s
$ tiddlywiki –?
$

Nothing happened after trying to run it.

Turns out that tiddlywiki.js expects TWO hyphens prior to options.  Unclear in the original posting.  All fixed.
