I'm trying to intall defects4j on ubuntu 18.04. but when I run the command:cpanm --installdeps . I get errors on jason and DBD.

faeze@ubuntu:~/defects4j$ cpanm --installdeps .

I installed jason and mysql, try running with root access, installed relevant libraries in cpanm, and updated all packages. but the error doesn't change.

I figured this out. It was due to cpanmetadb. So, I reinstalled cpan and its modules, and updated my packages and sudo itself. I do some of them with root access. Then I download and install JSON::Parse separately. After all these are done, I run the command cpanm --installdeps . and it worked.
