and when I try to install YAMl, I get this error .

Answer 1

'YAML' not installed, will not store persistent state is harmless.
As for not having permission to writing to /usr/local/share/man/man3, any reason to believe that's incorrect?
If you do have root access, did you follow the instructions in the error message? Launch cpan, and execute the following commands:
o conf make_install_make_command 'sudo make'
o conf commit
If you don't have root access, are you asking how to install modules to an arbitrary directory? I'd use perlbrew to install a perl in your home directory instead.

Answer 2

Are you running cpan as a regular user? No sudo or root access? That's probably why.

Answer 3

I have a similar problem. I add the following in the ~/.bashrc file.
vi ~/.bashrc
Then add these right after the definition of "PERL5LIB":
PERL_MB_OPT="--install_base "/home/usrname/perl5""; export PERL_MB_OPT;
PERL_MM_OPT="INSTALL_BASE=/home/usrname/perl5"; export PERL_MM_OPT;
Save, quit, and source the file:
source ~/.bashrc
Maybe you can use the below command to get the above information in terminal:
perl -I ~/perl5/lib/perl5 -Mlocal::lib
