如何修复laravel更新问题( Illuminate\Foundation\ComposerScripts::postAutoloadDump未能打开流:没有此类文件或目录)

Question

我目前正在开发一个laravel项目，使用一个现有的电子商务软件包，名为Bagisto。我已经从GitHub上的存储库下载了包文件，并在我的Ubuntu18.04操作系统上的xampp文件夹中掺杂了这些文件。当我在我的项目目录中的终端中启动composer update之后，问题就发生了，我收到了以下错误消息：

Loading composer repositories with package information
Updating dependencies (including require-dev)
Nothing to install or update
Generating optimized autoload files
> Illuminate\Foundation\ComposerScripts::postAutoloadDump

我已经尝试过一些方法来解决这个问题，比如更新composer和laravel框架版本，但仍然没有得到任何解决方案。

如果安吉·辛格的回答不管用。

• 您已经运行了composer install，并且在终端窗口中出现了一个通用错误，例如：Illuminate\Foundation\ComposerScripts::postAutoloadDump failed to ...........。
• 如果您的php文件代码有错误的语法(比如错误的use Class;语句)，那么上面的错误不会显示太多细节。
• 尝试运行php artisan migrate，然后将显示完整路径和问题文件的行号的问题所在。(例如：Warning: The use statement with non-compound name 'Log' has no effect in \path\to\your\file.php on line 5)
• 因此，有了这个详细的错误，我们可以转到特定的文件并解决问题(在本例中，从php类包含中删除use Class )。

希望有人能在这方面找到帮助！
