Question

我正在尝试将laravel应用程序从5.2升级到5.7版本，因为我编辑了composer.json文件并添加了以下行：

"require": {
    "php": ">=5.5.9",
    "laravel/framework": "5.7.*",
    "doctrine/dbal": "^2.5"
},

我运行作曲家更新，但出现此错误：

Script php artisan optimize handling the post-update-cmd event returned with error code 1

My application is throwing errors:
(1/1) ErrorException

升级laravel应用程序的过程是什么，我该怎么办？

Answer 1

您可以在Laravel文档中找到升级指南。您需要一次升级一个版本：

5.2 -> 5.3
5.3 -> 5.4
5.4 -> 5.5（5.5-> 5.5.42的附加步骤）
5.5 -> 5.6（5.6-> 5.6.30的附加步骤）
5.6 -> 5.7

此外，您可能应该在升级之前清除缓存：

删除/bootstrap/cache/files中的所有内容
清除缓存php artisan cache:clear
清除视图缓存以防万一php artisan view:clear
