尽管没有对composer.json进行任何更改,但AWS弹性beanstalk git部署由于composer问题而突然失败

Question

我在AWS Elastic Beanstalk中运行了许多环境.我使用git aws.push从git直接部署.

我使用composer.json来安装所需的php sdk.我很长一段时间没有改变这个文件,但它突然在所有环境中都失败了.

AWS日志的输出是

+ echo 'Found composer.json file. Attempting to install vendors.'
Found composer.json file. Attempting to install vendors.
+ composer.phar install --no-ansi --no-interaction

我的composer.json是:

{
"require": {
    "aws/aws-sdk-php": "2.7.*",
    "monolog/monolog": "1.0.*",
    "facebook/php-sdk-v4" : "4.0.*",
    "ext-curl": "*",
    "paypal/sdk-core-php": "v1.4.2",
    "paypal/permissions-sdk-php":"v2.5.106",
    "paypal/adaptivepayments-sdk-php":"2.*"
}
}

我注意到它确实需要aws-sdk-php,但版本不是5.3(在日志中提到).

5.3让我觉得php版本,检查php -vi get

php -v

我已经尝试重新安装以前安装得很好的旧版本,但它们也会因同样的错误而失败.这必须归功于环境.有谁知道最近是否有变化.

在项目的根目录中创建一个名为.ebextensions的文件夹.然后在其中创建一个名为01-composer-install.config的新文件,其中包含以下内容.

commands:
  01_update_composer:
    command: export COMPOSER_HOME=/root && /usr/bin/composer.phar self-update

option_settings:
  - namespace: aws:elasticbeanstalk:application:environment
    option_name: COMPOSER_HOME
    value: /root
