Question

有时候，不是每次，但随着趋势的增加，我会在symfony项目中发现作曲家安装的以下行为。我们在这里与不同的分支机构合作，在从功能分支切换回主分支后，需要进行作曲家安装。一切正常，但在最后一步，脚本在300秒后终止，而“buildBootstrap”。

> post-update-cmd: Sensio\Bundle\DistributionBundle\Composer\ScriptHandler::buildBootstrap
Script Sensio\Bundle\DistributionBundle\Composer\ScriptHandler::buildBootstrap handling the post-update-cmd event terminated with an exception

发生此错误一次后，再也无法在不直接挂起的情况下执行编辑器。

$> php -d memory_limit=-1 composer.phar -vvv install

按下回车后会直接挂起，没有输出，没有。我重新启动机器，可能下次工作，有时候不像上面描述的那样。

有没有人发现过同样的事情？

Answer 1

ScriptHandler :: buildBootstrap是composer中第一个在symfony项目中执行代码的任务。这意味着，php任务正在等待某些事情，而且这里没有太多可以考虑的事情。

您是否同时使用xdebug进行调试（mayby使用忘记的调试会话）？ xdebug是否在调试会话中运行并在断点处等待？

这可能是根本原因。

Answer 2

您收到的错误表明已超出执行脚本的时间限制。定义-d memory_limit=-1只会删除任何内存限制。您应该做的是添加-d max_execution_time=0（docs）。这应该可以解决你的问题。

Answer 3

我发现的一个修复是禁用CLI的xdebug。 Composer项目提到了这个修复，并且也是php关键字的别名，只有在使用php命令时才启动xdebug库。更多详情：https://getcomposer.org/doc/articles/troubleshooting.md#xdebug-impact-on-composer

Composer安装在ScriptHandler :: buildBootstrap中挂起
