cpan client- install_base value not used to install Text::Table

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

I was trying to install a module in my own directory via cpan (tried with perl 5.16.3 on CentOS 7; perl 5.30.0 on FreeBSD 12) but failed because install process tried to install Text::Table and Text::Aligner dependencies in a system wide directory (/usr/local) not writable by me as a lowly non-root user.

I had checked that the right directory had been specified for both Build.PL & Makefile.PL. What am I missing in the CPAN configuration file?

    I'd suggest using local::lib, as that will take care of configuring the modules in a way that they should install cleanly to a local directory. Both cpan and cpanm can make use of local::lib; I believe the former requires a bit of configuration (modern versions should ask you whether you want to use local::lib on initial configuration), and cpanm doesn't need any extra configuration; I'd recommend the latter.

    Of course, you could just install an entire build of Perl locally using perlbrew.

    Others have mentioned that PREFIX and --install_base work differently, and you probably don't want to combine them. You should probably change PREFIX to INSTALL_BASE.

    The direct problem you are having is because you've configured the --install_base option on the mbuild_arg, which is the build step. It needs to be set either on the install step (mbuild_install_arg) or the configure step (mbuildpl_arg). Setting it on mbuildpl_arg would correspond to how you were using the option manually.

    I would definitely recommend using local::lib instead of configuring this in your CPAN shell. And if you didn't want to use local::lib, you would be better off using the PERL_MM_OPT and PERL_MB_OPT environment variables to change the installation location. Either local::lib or using the environment variables manually has the advantage of working with any install tool, not just the CPAN shell.

      Thanks for explaining the details, especially about "mbuild_install_arg" option.

      One thing to note that module installs as expected when doing everything with Module::Build (./Build, etc) manually (second example). But fails when installing via cpan.

      I understand that "install_base" (Module::Build) is not same as PREFIX (ExtUtils::MakeMaker).

      Are you suggesting that cpan uses Module::Build to build the module but then uses ExtUtils::MakeMaker to install it (depending on value of INSTALL_BASE) even though "MB" is "prefer_installer" in the CPAN configuration?

        I am suggesting maybe edit config to not use prefix and see what happens. The manual command shown doesn't match the automatic one.
