Description hakan 2017-06-28 13:34:11 UTC

If devel/hadoop2 is already installed on the system, www/yarn will fail to install:

Installing yarn-0.24.6...
pkg-static: yarn-0.24.6 conflicts with hadoop2-2.7.2_2 (installs files into the same place).  Problematic file: /usr/local/bin/yarn
*** Error code 70

Since yarn 0.16 the alternative alias /usr/local/bin/yarnpkg should be available.

Here is the already closed upstream issue: https://github.com/yarnpkg/yarn/issues/673

Hi Hakan,

thanks for reporting.

On Mac, the alias is a solution because the two "yarn" are installed in different places.

Here there is a conflict, one "yarn" would overwrite the other one.
The solution is not trivial, but I'll figure out something.

Pending maintainer feedback and patch.

In the meantime a CONFLICTS_INSTALL can be set.

Assign demon@ accordingly (maintainer of conflicting port, and committer)

Comment 5 luca.pizzamiglio 2017-07-08 10:38:57 UTC

This is how would solve the issue.

#1 Adding an option to www/yarn, to optionally install yarn (default: yes)
#2 Adding a new port (name to be defined, like www/yarn-compat), with the option set to no

Basically, the new port is a FLAVOR of www/yarn, but AFAIK FLAVOR support is not yet present.

I'd like to have some feedback, before to start

Seems fixed. Could this closed.
