I am looking for an import option that could be used to activate a given directory only if it exists. The option name could be --activate-if-exists. A message could be printed if the activation was not done. This message could be suppressed, if the --quiet option is set too. If this is a reasonable feature, could this be implemented please.

guess_shell will warn with unassigned variable warnings if $SHELL is not set.

Also, if $SHELL is 'tcsh', you get 'sh' style output instead of 'csh' style

Suggested fix:

  my $shellbin
    = defined $ENV{SHELL}
      ? ($ENV{SHELL} =~ /([\w.]+)$/)[-1]
    : ( ( $^O eq 'MSWin32' && exists $ENV{'!EXITCODE'} )
      ? 'bash'
    : ( ( $^O eq 'MSWin32' && $ENV{PROMPT} && $ENV{COMSPEC} )
      ? ($ENV{COMSPEC} =~ /([\w.]+)$/)[-1]
    : ( ( $^O eq 'MSWin32' && !$ENV{PROMPT} )
      ? 'powershell.exe'
    : 'sh' )));

  for ($shellbin) {
    return
        /t?csh$/                 ? 'csh'
      : /fish$/                  ? 'fish'
      : /command(?:\.com)?$/i    ? 'cmd'
      : /cmd(?:\.exe)?$/i        ? 'cmd'
      : /4nt(?:\.exe)?$/i        ? 'cmd'
      : /powershell(?:\.exe)?$/i ? 'powershell'
                                 : 'bourne';
  }
}

Hello,

I am working on a system where I do not have root privileges. I am trying to install local::lib so that I can then install other perl modules locally.

I was following the bootstrap instructions and tried the 2 following commands:
perl Makefile.PL --bootstrap
perl Makefile.PL --bootstrap=~/perl5

Both fail with:

Can't locate local/lib.pm in @INC (@INC contains: lib /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5 .) at Makefile.PL line 110.

I am confused as it seems it is then asking for local::lib, which is is precisely what I am trying to install?

Thanks in advance for the help.

When installing local::lib over our suite of perl versions, the latest version of local::lib is failing for perl-5.8.9.

Output from the tests is attached.
local_lib_fail.txt

inc/CPANBootstrapper.pm uses CPAN::HandleConfig::require_myconfig_or_config() which did not exist until CPAN v1.86_52.

Please bump the prereq for CPAN to a slightly higher version.

Powershell has existed on Linux and Mac for a while now, but guess_shelltype will only give powershell if $^O is windows.

Powershell can be detected by exists $ENV{PSModulePath}.

If make (or equivalent) isn't installed, bootstrapping will fail mysteriously. I just beat my head into the wall trying to figure out the problem until I remembered that build-essential wasn't installed.

local::lib should check that $Config{make} is in PATH and abort with a helpful error.

re: miyagawa/cpanminus#263

When you setup local::lib on the shell, you'll get environment variables such as:

export PERL5LIB="/Users/miyagawa/perl5/lib/perl5:$PERL5LIB";

suppose you don't have the ~/perl5/lib/perl5 directory yet, and run
perl with that PERL5LIB, your @inc looks like:

@inc:
/Users/miyagawa/perl5/lib/perl5
/Users/miyagawa/.plenv/versions/5.18.0/lib/perl5/site_perl/5.18.0/darwin-2level
...

Once you have installed at least one arch-dependent (XS) module, your
@inc becomes:

@inc:
/Users/miyagawa/perl5/lib/perl5/darwin-2level
/Users/miyagawa/perl5/lib/perl5
/Users/miyagawa/.plenv/versions/5.18.0/lib/perl5/site_perl/5.18.0/darwin-2level
...

If you 'use local::lib' in your code, this isn't an issue since local::lib puts archlib in @inc explicitly. With PERL5LIB, perl doesn't put archlib unless the directory exists :/
