问题
I am facing warning statements in my travis builds.
Warning: This development build of composer is over 30 days old. It is recommended to update it by running "/home/travis/.phpenv/versions/5.3.26/bin/composer.phar self-update" to get the latest version.
How do I then run this?
See an e.g. here
回答1:
It is not such a good idea to hard-code the php path as paths might change when Travis gets update. I suggest simply calling
composer self-update
回答2:
inside your travis.yml
make sure you have this section
before_install:
- php /home/travis/.phpenv/versions/5.3.26/bin/composer.phar self-update
in order to run the self-update properly
