【问题描述】：

我正在使用 symfony 2 并尝试运行 composer install --ignore-platform-reqs

以前可以，但现在重新设置时出现错误require_once(app/autoload.php): failed to open stream: No such file or directory

下面的完整错误：

Loading composer repositories with package information

问题是它以前工作过。所以看起来app/autoload.php 总是在正确的位置。现在我正在进行全新安装，但它不存在。

我能够在vendors/autoload.php 中找到autoload.php，但不确定为什么它位于错误的位置。

我的 composer.json：

【问题讨论】：

“警告：锁文件不是最新的，因为 composer.json 中的最新更改”。看起来有人弄乱了 composer.json 并且没有创建新的锁定文件。可能会尝试删除锁定文件并再次更新。恐怕行不通。 app/autoload.php 应该已经签入到您的源代码存储库中。它不会生成，除非是一个新项目。只需从工作应用中复制即可。

【参考方案1】：

安装后，composer 从这个文件运行一个脚本：ScriptHandler.php，它获取配置键 symfony-app-dir 的路径并从文件中调用下一个脚本：build_bootstrap.php

如果您没有autoload.php 文件，您可能需要从autoload.php.dist 文件中复制它

【讨论】：

是的，应该在那里，但它被意外删除了。
