Laravel 7 - 类哈希不存在

Question

我有一个新创建的 Laravel 应用程序，其中安装了 Backpack。过去几天我一直在努力将其部署到 Google Cloud。

我正在使用 Laravel 7，我正在尝试部署到 Google 云应用程序引擎并收到Class hash does not exist错误。我也遇到过几次Class view does not exist。

我很确定这与部署环境有关，而不是我的更改。我这么说的原因是，今天早上我更新了backpack/crud版本，应用程序在部署后成功运行。

因此，为了测试，我在没有进行任何更改的情况下再次部署，上传了零个文件，并且遇到了同样的问题！

如果有人能给我指出我可以尝试什么，那就太好了。

我经常遇到类似的问题。虽然不完全相同，但可能足够相似，这将为您解决问题。对我来说，这通常是构建的缓存问题。

如果在 Composer 更新后发生这种情况，并且您忘记--no-dev在下次更新时执行并删除内容，则可能会发生此错误。

修理：

无论是无开发问题，还是构建过程中的一般缓存问题，请手动进入 bootstrap/cache 文件夹并删除文件，尤其是软件包文件。或者，如果您已将环境设置为DEV，并且实际上没有拉入开发包，请返回并更新作曲家（不带 no-dev）

或者，如果您仍然遇到困难，您可以尝试不使用脚本更新 Composer，然后安装。就我而言，有一次它仍在尝试加载调试栏。
