由于恶劣的环境设置，Jenkins无法更新作曲家

Question

Console log:

+ COMPOSER_HOME=/home/jenkins/composer
+ HOME=/home/jenkins
+ php composer.phar install
         [RuntimeException]                                                                        
  The HOME or COMPOSER_HOME environment variable must be set for composer to run correctly  

This used to work, now it's giving me this error. I am even setting these vars explicitly now, but it still fails. What happened to Jenkins to cause this failure? How do I fix it? I have tried a couple things I've found here on SO but none have helped.

Answer 1

There is an error with the latest version of composer. First, update to this alpha version using this command: export COMPOSER_HOME=/root && /usr/bin/composer.phar self-update 1.0.0-alpha11 More info here
