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?

  • Component changed from operational to code-frontend-cli
  • Keywords easy added
  • Owner somebody deleted
  • Summary changed from Unable to run some commands to make the error message more helpful in case of no 'tahoe' alias

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:

  • Milestone changed from 1.7.0 to 1.6.1

The error in comment:2 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.
