【问题描述】：

我正在尝试将我的 laravel 项目框架从 5.5 升级到 5.7 但无法做到..

当我将 composerjson 要求更改为 laravel 升级文档并在项目终端上点击 composer update 时，它的输出如下：

composer update
Do not run Composer as root/super user! See https://getcomposer.org/root for details

尝试了许多互联网上可用的方法，但仍然存在问题

只是想升级项目 laravel 以获得新功能..

有人知道吗？我该如何解决这个问题并继续使用新的 laravel？

提前致谢。

【问题讨论】：

你安装 PHP 7 了吗？
禁用或删除 composer.json 文件中的所有包，只保留 laravel 包，然后更新安装所有包
您至少需要 PHP 7.1.3 才能使用 Laravel 5.6 及更高版本。
@umefarooq 我尝试了你的方式..在升级脚本 php artisan 优化处理返回的 post-update-cmd 事件并返回错误代码 1 和运行 php artisan --版本 gor 此错误在 ProviderRepository.php 第 208 行：找不到类“Spatie\Activitylog\ActivitylogServiceProvider”
cartalyst/stripe-laravel v7.0.0 requires illuminate/support 5.5.*。您需要使用该库的更新版本，因为 7.0.0 版本需要 Laravel 5.5。（请不要叫我“兄弟”）。

标签： javascript php laravel

【解决方案1】：

注意：请先检查您的 PHP 版本，了解 laravel 所需的版本。

按照以下步骤为您的项目升级 laravel 框架的最佳方式

备份您的 composer.json 文件
从 composer.json 文件中删除所有第三方包或从 laravel git 存储库中获取最新的 composer.json https://github.com/laravel/laravel
从 app.php 文件中注释所有第三方包服务提供商（对于 Laravel 5.5 以下的版本）
现在在终端运行 composer update 命令
一旦 Laravel 更新完成。现在再次安装所有第三方包并在 app.php 文件中启用第三方服务提供商。

更新： 如果您尝试升级 laravel 5.5 及更高版本，请跳过第 3 步。同样对于 laravel 5.5 及更高版本，无需在第 5 步中启用第三方包服务提供商。

很高兴为您的项目更新 laravel。

【讨论】：

我用过这个，它奏效了。在此之前尝试了很多没有用的东西。

【解决方案2】：

因为这条线

cartalyst/stripe-laravel v7.0.0 需要照明/支持 5.5

谢谢大家的帮助...

我只是更新 cartalyst 包和作曲家更新它的工作

结论：要更新你的 laravel 项目，记得升级你的 3rd 方包..

【讨论】：

谢谢兄弟....我有旧的 3rd 方包（不再在我的应用程序中使用）...删除它后，我就可以升级 laravel 版本了..

【解决方案3】：

在运行 composer update 之前你必须先安装这些包，同时在你的 composer.json 文件中将 laravel 的版本更改为 5.7。

Ubundu 终端命令

sudo apt install php7.2 libapache2-mod-php7.2 php7.2-mbstring php7.2-xmlrpc php7.2-soap php7.2-gd php7.2-xml php7.2-cli php7.2-zip

PHP >= 7.1.3
Ctype PHP 扩展
JSON PHP 扩展
BCMath PHP 扩展

删除供应商文件夹并尝试composer update

【讨论】：

【解决方案4】：

只需在 composer.json 文件中将 laravel 更改为 5.7.* 并运行 composer install 命令

【讨论】：

【解决方案5】：

php -v

如果低于 7 ，也许你有类似的别名

php7 -v

或

php72 -v

许多服务器使用 php 别名
