perlbrew perl installation, is build folder necessary after install?

Question

I installed perl5 using perlbrew using the following command

perlbrew install -v perl-5.18.2 -Dusethreads -n --as perl-5.18.2_WITH_THREADS

After the installation, I find that this folder "~/perl5/perlbrew/build" takes 182MB. Is this folder necessary? If not could I remove that?

Answer 1

不必要，您可以安全地删除它。

Answer 2

If you run

perlbrew clean

that will automatically cleanup the build and dist directories.
