| Subject: | build_requires_install_policy=no and deep dependency trees |
When installing Dist::Zilla on a bare Perl environment (core and only a
few modules (CPAN, File::HomeDir, Task::Reporter) under the CPAN config
option "build_requires_install_policy set to 'no', the following modules
are not installed as a result:
- Module::Runtime 0.012
- Hook::LexWrap
The problems seems to be an issue related to the handling of deep
dependency trees:
- Hook::LexWrap is built for Test::SubCalls that seems to be built
before Sub::UpLevel. So Hook::LexWrap seems to be marked as
"build_require" because it is a dependency of a build_requires. So as a
result Sub::UpLevel is installed but without Hook::LexWrap, despite
Sub::UpLevel is a "requires".
- Module::Runtime 0.012: it is a dependency of Class::Load (a direct
dependency of Dist::Zilla) and Module::Implementation. I've not yet
figured out the reason why it is marked as "build_requires" and so not
installed. Is it because Module::Implementation is itself a dependency
of Class::Load?
In addition, ExtUtils::MakeMaker 6.62 is built and so used during the
build, but not installed as a result. So if later one of the modules is
upgraded it will be installed with the older version of EUMM.
Here is my CPAN config:
