Can you help me here?

I never really used CPAN, so it may be a silly question. Sorry. But when I try to use it with the command "install Statistics::R" it return the following error:

Failed during this command:  FANGLY/Statistics-R-0.30.tar.gz  : make_test NO

Any advices about that?

NOTE: I'm running a Fedora 17 and perl 4:5.14.3-218.fc17, and I ran cpan with "sudo perl -MCPAN -e shell"


I tried to install it by hand using the commands "make Makefile.PL", "make", "make test", "make install".

But when I rum "make test". It fails and returns this error message:

Test Summary Report ------------------- t/08-errors.t (Wstat: 256 Tests: 10 Failed: 1) Failed test: 10 Non-zero exit status: 1 Files=9, Tests=10195, 64 wallclock secs ( 8.93 usr 0.48 sys + 54.43 c +usr 4.36 csys = 68.20 CPU) Result: FAIL Failed 1/9 test programs. 1/10195 subtests failed. make: ** [test_dynamic] Erro 1

    Any advices about that?

    Get more information, run Makefile.PL yourself

    step out of cpan, cpan>look Module and run perl Makefile.PL yourself, and confirm perl -V

    Or the same with cpanp -z Module then perl Makefile.PL ...

    Do you have the prerequisite r-studio?

      cpan>look Statistics::R

      Returned this:

      # Testing Statistics::R 0.30, Perl 5.014003, /usr/bin/perl # Failed test 'Internal error' # at t/08-errors.t line 40. (in cleanup) Error stopping R: 256 # Looks like you failed 1 test of 10. Failed 1/9 test programs. 1/10195 subtests failed. make: ** [test_dynamic] Erro 1

      This is the code in 08-errors.t

      #! perl use strict; use warnings; use Test::More; use Statistics::R; SKIP: { skip 'because tests hang on Win32 (bug #81159)', 1 if $^O =~ /^(MS) +?Win32$/; ok my $R = Statistics::R->new(); is $R->run(q`a <- 1;`), ''; eval { $R->run( qq`print("Hello");\nprint(ASDF)` ); }; #diag "Diagnostic: \n".$@."\n"; ok $@, 'Runtime error'; is $R->run(q`a <- 1;`), ''; ok $R = Statistics::R->new(); eval { $R->run( qq`print("Hello");\nprint "ASDF"` ); }; #diag "Diagnostic: \n".$@."\n"; ok $@, 'Syntax error'; # Actual error message varies depending on locale is $R->run(q`a <- 1;`), ''; use_ok 't::FlawedStatisticsR'; ok $R = t::FlawedStatisticsR->new(); eval { $R->run( qq`print("Hello");\ncolors<-c("red")` ); }; #diag "Diagnostic: \n".$@."\n"; ok $@, 'Internal error'; # THIS IS LINE 40 !!! }; done_testing;

        Since you are having so much trouble with this installation, maybe you should just use Perlbrew to install a fresh, independent, and current Perl installation. Then use the guide on the Perlbrew site to install cpanm and then you are running on EZ-mode.

        Also, which versions of R and Perl are you running?

        So all other tests pass? In that case, ignore it and install the module -- you might also report upstream to rt://Statistics-R
