我有一个使用Passport的Laravel应用程序来提供API身份验证。该应用程序是使用git和post-rereceive挂钩进行部署的。接收后脚本的一部分是composer安装。自从我加入Passport以来，每当我部署我的应用程序时，API都会在身份验证门后面的路由上中断，堆栈跟踪粘贴在下面。
当我进入应用程序的服务器并运行与接收后挂钩中完全相同的composer install命令时，一切都会恢复正常。
当部署发生时，我没有看到来自git的任何错误消息，而且当部署发生和手动运行命令时，我似乎从composer install得到了相同的输出。
以下是composer install命令的部署输出：
remote: Loading composer repositories with package information
remote: Installing dependencies (including require-dev) from lock file
remote: Nothing to install or update
remote: Generating autoload files
remote: > php artisan clear-compiled
remote: The compiled class file has been removed.
remote: > php artisan optimize
remote: Generating optimized class loader
remote: Compiling common classes
当我手动运行命令时，我看到的是：
Loading composer repositories with package information
Installing dependencies (including require-dev) from lock file
Nothing to install or update
Generating autoload files
> php artisan clear-compiled
The compiled class file has been removed.
> php artisan optimize
Generating optimized class loader
Compiling common classes
这是怎么回事？部署似乎是在安装Passport的某个组件的旧版本，然后在手动运行composer install后进行更正，但我不知道为什么会发生这种情况，尤其是为什么每次部署新更新时都会发生，即使composer.json或composer.lock没有更改。
这是上面提到的堆栈跟踪：

好的，所以问题出在artisan optimize命令中。正如我在对我的问题的评论中所指出的，我注意到优化命令通过post-rereceive钩子运行的速度比手动运行该命令快得多。
在我的部署环境中，我在一个与基本laravel目录分离的目录中有一个composer.phar文件当我在基本目录中创建了一个到composer.phar的软链接时，一切都恢复了正常
我仍然不确定为什么会出现这个问题，但似乎Laravel在从后接收挂钩运行时可能找不到我的composer实例，尽管我的环境设置为从命令行运行相同的命令效果良好。
