cpan problems with 02packages.details.txt.gz and 03modlist.data.gz

[David Christensen]

Hello, world!

I am having trouble with cpan on Cygwin:

dpchrist@w2k30g:~/.cpan/sources$ cpan

cpan shell -- CPAN exploration and modules installation (v1.70_54)
ReadLine support enabled

cpan> install Class::Base

As best I can tell, cpan thinks the following file is corrupt:

~/.cpan/sources/modules/02packages.details.txt.gz

and then has trouble processing the following file:

~/.cpan/sources/modules/03modlist.data.gz'


I don't know how to "check the validity of the index file by comparing
it to more than one CPAN mirror".


I tried blowing the two files away, restarting cpan, and installing a
module, but cpan simply downloaded the files again and proceeded with
the same errors.


I STFW and came up with a message by a lady who had a same/similar
problem. She said that it was caused by a rogue "~" file or folder in
her directory tree. Removing it fixed the problem. I searched my
system, found "C:\~", and removed it, but no luck.


Any suggestions?


TIA,

David

Perhaps Cygwin perl gets confused with the '~', sometimes
thinking it a real directory (eg, presence of a C:\~) and other
times expanding it to a home directory (/home/dpchrist/). It
might be worth trying to again remove C:\~, and then start
the CPAN.pm shell but first reconfigure it:
cpan> o conf init
and try choosing the build and source directories with a root
directory of something like C:/.cpan/.

Thanks for the reply!


Here's what I did:

1. Blow away C:\~

2. Run cpan:

cpan> o conf init
...
CPAN build and cache directory? [/home/dpchrist/.cpan] /cygdrive
/c/.cpan/
...
File to save your history? [/home/dpchrist/.cpan/histfile] /cygd
rive/c/.cpan/histfile


It worked!


Thank you,

David
