composer dump-autoload --no-dev 报错问题

问题描述

“autoloader文件” 是指 vendor/composer/ 下的那几个 以autoload_ 开头的文件。

我想观察下 composer dump-autoload 执行后 autoloader文件中的变化情况，所以新创建了一个laravel项目，然后执行 dump-autoload 命令，并且分别尝试了 -o 和 –no-dev命令选项。先是执行了 composer dump-autoload 没有报错（autoloader文件中有变化，没啥影响，只是位置信息的变化），然后执行composer dump-autoload -o 也没用问题，然后执行 composer dump-autoload –no-dev 就提示某些类找不到。后来也尝试了 composer dump-autoload -o –no-dev，也试了重新创建了新项目直接执行 composer dump-autoload –no-dev 还是不行。

发现

composer dump-autoload –no-dev 执行后 Facade\Ignition 命名空间对应的映射关系 在 autoloader文件中消失了，但是 Facade\Ignition 命名空间并非在 autoload-dev 块中。
facade/ignition 包的json文件（没有改动过）：
