I just installed perl and am trying to install CPAN without root privilege.

As I run cpan App::cpanminus, I got into an infinite loop echoing Waiting for read lock on '~/.cpan/FTPstats.yml'. I tried removing the file and the error persists.

Highly appreciate any solution and thanks in advance!

  You might want to try
    install CPAN
    reload cpan
  to both upgrade CPAN.pm and run the new version without leaving
  the current session.
