Problems with PHP YAML within Travis CI

问题

Edit: I believe the problem is that YAML doesn't work on 5.4/5.5.

I have a library that is setup in Travis CI and that uses the PHP YAML PECL extension. However, I am unable to get the YAML extension to work in Travis & PHP 5.4, and I'm curious if anyone else has? No amount of Googling has solved my problem.

Here is the output of Travis:

$ git clone --depth=50 --branch="master" git://github.com/titon/IO.git titon/IO

回答1:

Automating PECL installs is a problem that is encountered not just on Travis CI. In this case, a pseudo-expect script can be created by sending a cariage return into the stdin of the PECL installer which will in turn pass it on to the configure script that is prompting for input:

printf "\n" | pecl install yaml

A working version of your .travis.yml would then look something like:

language: php

php:
  - 5.4
  - 5.5

before_script:
  - printf "\n" | pecl install yaml-beta
  - echo "extension=yaml.so" >> ~/.phpenv/versions/$(phpenv version-name)/etc/php.ini
  - composer install --dev

回答2:

.travis.ci

language: php

php:
  - 5.4
  - 5.5
  - 5.6

sudo:
  false

before_install:
  - pecl channel-update pecl.php.net
  - (CFLAGS="-O1 -g3 -fno-strict-aliasing"; pecl install yaml < /dev/null &)

addons:
  apt:
    packages:
      - libyaml-dev
