How can I install `Thread::Pool` from CPAN?

Question

I'm using cpanm to install Perl modules, but I can't install Thread::Pool for some reason:

$ sudo cpanm Thread::Pool

fails and the log file says:

Answer 1

Well, the problem is that Thread::Tie (one of the prerequisites) is failing its tests. According to CPAN Testers, Thread::Tie has never passed its tests on Perl 5.10.1, and has 6 failure reports. The couple I checked look just like yours.

You can use cpanm -n to skip running the tests and install anyway, but there's no guarantee that the resulting module will work properly. It's possible that the problem is in the test scripts rather than the module itself, but that's not the most likely explanation.

You can try reporting a bug in Thread::Tie, or try debugging it yourself.

Answer 2

Thanks for reporting.

I've just uploaded new versions of all modules involved. Fortunately, most of the problems were actually in the test-suites and not in the code itself.

Please let me know if this does solve it for you or not.
