Hi, while upgrading outdated I've got the following conflict. Thank you for your help.

On future tickets please use WikiFormatting when quoting from terminal output or log files for better readibility, copy the port maintainers

port info --maintainer py27-pep8 py27-pep8-157

and fill in the Port field of the ticket. Thanks.

Note that, according to your terminal output, the conflict is between py27-pep8 and py27-pep8-157. Ports that have a dependency on py-pep8 currently depend on py-pep8-157 due to a regression in the 1.6.x series of py-pep8 that, in particular, effected py-flake8. Recently released py-pep8 1.7.0 claims to have fixed this issue so upgrading to this version as well as latest py-flake8 1.5.2 should allow this conflict to be removed.

In the meantime, if you really don't need to use py-pep8 1.6.x, just deactivate this port. No other ports currently depend on it.

sudo port deactivate py27-pep8

I can confirm that port py-pep8-157 was introduces to resolve an issue, regarding incompatibility with py-flake8, which remained unresolved upstream for quite some time. If pep 1.7.0 was finally released, this might now be fix and we could get back to one single port. Will look into this later.

Anyway, the conflict between py27-pep8 and py27-pep8-157 is by design. It's actually the same package, just a different version. In order to minimize any conflicts to occur for users with an existing install base, in r141870 I replaces the hard pep8 dependency with a path dependency. This way any of the two pep8 ports should satisfy the dependency. However, apparently for some reason this does not work for you.

I would suspect that some other port forces the installation of py27-pep8-157 (py27-flake, is the only good candidate I could think of), this cases py27-pep8 to be deactivated. However, py27-pep8 is part of the list of outdated ports. This is just a guess though, but if correct py27-pep8 now should already be deactivated. Another port upgrade outdated would not consider py27-pep8 and the upgrade will finish without error.

I CC the maintainer of py-spyder as well.

I updated pep8 to 1.7.0 in r145580, see also ticket #50576 (comment 4).

[petrrr]

The py-pep8-157 was retired in r145602 (see also r145606).

[petrrr]

r145607 removes the conflict with py-pep8-157.

And as a side note: r145608 updated py-flake8.
