Subject: cpan shell exits with error "Unknown shell command 'cpan[1]>'"
I have added my installed perl's bin\ folder to my PATH and am trying to start the cpan shell by simply typing "cpan" in a standard cmd.exe command prompt on Windows 7. The cpan shell immediately exits with an error if I try to enter it with my current directory being on the C: drive: ########## C:\>cpan Terminal does not support AddHistory. cpan shell -- CPAN exploration and modules installation (v1.9800) Enter 'h' for help. Unknown shell command 'cpan[1]>'. Type ? for help. Terminal does not support GetHistory. Lockfile removed. C:\> ########## If I switch to seemingly any other drive letter then it works fine: ########## C:\>K: K:\>cpan Terminal does not support AddHistory. cpan shell -- CPAN exploration and modules installation (v1.9800) Enter 'h' for help. cpan[1]> ########## This is most unfortunate since I normally work on the C: drive :-(

Can you start the shell from C: with perl -MCPAN -eshell ?

No, that has exactly the same result -- works fine from K: but exits with the same error from C:

I've just discovered that I have the same problem with CPANPLUS, so I've reported it there too (see CPAN RT#79064), and I'm now thinking the problem is really elsewhere (Term::ReadLine?), but if a fix is made elsewhere then you'll perhaps want to add a prerequisite minimum version on the updated dependent.

Now fixed in blead by commit 4cc026083a to Term::ReadLine. Please see #79064 for the gory details.
