Hello Pen,

Permission denied - /home/pt/.ri/cache/.doc_dirs (Errno::EACCES)
It seems that there are some directory you can’t read in ~/.ri.
Try
sudo chown -R pt home/pt/.ri
to recursively regain access to the directories, it should solve at
least this issue.
Cheers,
sudo find / -name ‘ri’
the following is what i get

Hello Pen,
2010/4/8 Pen T. [email protected]:
sudo find / -name ‘ri’
The directory ‘ri’ is looking for is not called ‘ri’ but ‘.ri’ (note
the dot at the beginnining of the name that make the directory
‘invisible’ from a simple ‘ls’). Try
ls -la /home/pt/.ri
to look at it directly. What did the command
sudo chown -R pt home/pt/.ri
answer to you ?

Sorry, typo on my side. It should be read
sudo chown -R pt /home/pt/.ri
(forgot the root slash). That should work now.
Cheers,
