Hi,

I'm getting this error on OS X 10.5.2 when trying to run any command minus start/stop and create-*. Anyone know why this might be?

Thanks!

Thanks for the bug report, prmr. I'm sorry that it fell by the wayside for four months -- I don't know if I ever noticed this ticket before now. I'm changing the title to reflect what I think is the issue here -- that the error message when there is no alias registered for 'tahoe' should be more helpful and explain that the tahoe stats command expects either a dircap or an alias on the command-line, or else for there to be a dircap registered under the default 'tahoe' alias in the aliases file.

I'm also marking this ticket as "easy" -- a young hacker who wants to get into Tahoe-LAFS hacking should be able to fix this ticket easily enough even if they aren't familiar with the codebase.

I'm getting a different exception (Tahoe 1.5.0 r4044 with Python 2.6 on Windows Vista), but I think it's probably the same issue:

Duplicate of #939 (actually the other way around, but that ticket has more information).

The error in comment:70678 wasn't the same issue; it was due to --node-directory not being set (on Windows there is no default node directory when the registry entry set by the allmydata.com client is not present). I'll open another ticket for that.
