Migrating modules shows inconsistent result about plenv

[miyagawa]

I have no idea since this is a terrible way to report an issue.

Run perl -v (and -V) to see which version of the perl you're using, and make sure you use the perl for 5.20.1 you just installed.

Particularly the Template one. I am trying to run that, and it is not found in my @inc.

Run what?

when you say "my @INC" which INC directories?

What's the error message you got?

When you ran migrate-modules which directories did it install into?

i'm sure by answering them the solution would be obvious and i suspect you're not running that perl you just pasted.

[marr]

So I am trying to just:

plenv exec perl -e 'use Template'
Can't locate Template.pm in @INC (you may need to install the Template module) (@INC contains: /opt/boxen/plenv/versions/5.20.1/lib/perl5/site_perl/5.20.1/darwin-2level /opt/boxen/plenv/versions/5.20.1/lib/perl5/site_perl/5.20.1 /opt/boxen/plenv/versions/5.20.1/lib/perl5/5.20.1/darwin-2level /opt/boxen/plenv/versions/5.20.1/lib/perl5/5.20.1 .) at -e line 1.
BEGIN failed--compilation aborted at -e line 1.

I ran migrate-modules but I am not sure what dirs it installed the modules into. Is there a way to find that out?

[miyagawa]

The cpanm log should be found somewhere in ~/.cpanm/work/.

[marr]

I see some dirs in there and they look to contain the actual modules themselves.

[miyagawa]

sigh there's a build.log file in those directories and you can see the actual log.

[marr]

Sorry bout that. Here is an example of a build.log:
Installing /opt/boxen/plenv/versions/5.20.1/lib/perl5/site_perl/5.20.1/darwi n-2level/.meta/App-cpanminus-1.7014/MYMETA.json
Other build.log files there are pointing to my old perl install:
Installing /Users/dmarr/perl5/perlbrew/perls/perl-blead/lib/site_perl/5.19.6 /darwin-2level/.meta/strictures-1.005005/install.json

[miyagawa]

What about the log that installs Template?

[miyagawa]

If newer invocation of cpanm and migrate-modules run was installing them
into your old perlbrew that is your setup being wrong and have cpanm in
perlbrew PATH. (Run which cpanm)

You basically have to nuke perlbrew environment before all of this since
obviously it will conflict.

[marr]

which cpanm points to /opt/boxen/plenv/shims/cpanm

I ran plenv migrate-modules system 5.20.1 and got a failure. Here is the relevant build.log: tail build.log

[miyagawa]

That is not really relevant because it is just a failure of installing
mod_perl. It should've installed other modules just fine no?

Can you please more specific and not strip the part you think is not
important but actually is? There have been so many unnecessary back and
forth because you supply info just arbitrarily.

[marr]

Well I ended up running the migrate task again and it seems to be working this time. I imagine it was something to do with perlbrew still being in the environment.
Thanks for the help.
