[Newbies] How to install packages? Scamper chicken and egg problem

Mon Dec 31 17:11:51 UTC 2007

Thanks, Janko!!!

Alas, this does not work on my Mac. Right-clicking on the desired
version (or anywhere on the SqueakMap Package Browser) brings up the
"halo" of things I can change / do to the SPB window (menu icon,
collapse icon, viewer icon, etc.). No popup.

BUT! AHA! Your tip just needs to be translated into Mac-speak!

A bit of flailing around with key-chord / mouseclick combos reveals...
I need to press Alt (or Option) and left-click on the version number
to get the popup menu!!!! Ta-da!!! It installs!!!

And--I just noticed this--there is a tiny square in the upper-right
corner of the package list window. Clicking on this tiny square also
brings up the popup menu.

(Wow, I gotta say, to be painfully honest, that step is completely
non-obvious on a Mac! I'll see if I can figure out who developed the
SPB and leave a note about the popup menu. Something that is so
important shouldn't be that hard to find. The square needs to be a lot
bigger, and the action to bring up the menu needs to be something more
intuitive than Alt-leftclick. Maybe there could be a button that
appears in the description window, or left-clicking on the URL in the
descriptiion window will bring up the popup menu?)

Anyway, back to the Scamper install. Well, it did install, almost.

Now I get a pop-up error window after the install chugs along for a
few seconds: "Error occurred during install: UndefinedObject>>flush.
Would you like to open a debugger?" I click "No". I am a newbie and
not yet debugger-compatible. Afterwards, I still get the same "parse"
error when I try to find the Scamper object. But maybe that is a
incompatibility between the current versions of the VM, Image, and
Scamper? I'll try installing a few other packages and see how far I
get.

OK, I tried to install the big "Balloon 3D" package, and it installed
just fine, and I can find a "B3DMorph" object and play with it without
errors, so I am thinking that the Scamper "parse" and "flush" errors
must be unique to Scamper.

Thanks again for the help!!!
