| Subject: | CPAN's o conf init/FirstTime.pm: trailing backslash in cpan_home directory path |
During initial manual configuration of CPAN, when asked the question
CPAN build and cache directory?
answer with a path with a trailing backslash, e.g. C:\vanilla-
perl\.cpan\
Later exit and try to restart CPAN:
Show quoted text
> cpan
CPAN: File::HomeDir loaded ok
Error while requiring CPAN::Config:
Can't find string terminator "]" anywhere before EOF at C:/vanilla-
perl/perl/lib/CPAN/Config.pm line 13.
Compilation failed in require at C:/vanilla-perl/perl/site/lib/CPAN/
HandleConfig.pm line 385.

'cpan_home' => q[C:\vanilla-perl\.cpan\],
The trailing backslash escapes the delimiter and creates a syntax
error. This is always reproducable for the latest release of CPAN:
Show quoted text > perl -MCPAN -e"print $CPAN::VERSION"
