php - Travis CI 中 PHP YAML 的问题

Question

编辑:我认为问题在于 YAML 不适用于 5.4/5.5。

我有一个在 Travis CI 中设置的库，它使用 PHP YAML PECL 扩展。但是，我无法让 YAML 扩展在 Travis 和 PHP 5.4 中工作，我很好奇其他人有没有？谷歌搜索再多也解决不了我的问题。

这是 Travis 的输出:

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

自动化 PECL 安装是一个不仅在 Travis CI 上会遇到的问题。在这种情况下，可以通过将回车符发送到 PECL 安装程序的标准输入来创建伪expect 脚本，PECL 安装程序随后将其传递给提示输入的配置脚本:

printf "\n" | pecl install yaml

你的 .travis.yml 的工作版本看起来像这样:

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
