Server 500 在 linux 上启动新的 php-laravel 项目时

Question

我的 php 经验为零，但需要启动我已克隆的现有应用程序（应该是功能性的），以快速测试它。我想我已经很接近它的工作了。

如果我运行php artisan serve:

[franck@franck-vee appliweb]$ php artisan serve
Starting Laravel development server: http://127.0.0.1:8000
[Tue Sep 28 13:31:56 2021] PHP 8.0.10 Development Server (http://127.0.0.1:8000) started
[Tue Sep 28 13:32:00 2021] 127.0.0.1:34716 Accepted
[Tue Sep 28 13:32:00 2021] 127.0.0.1:34716 Closing
[Tue Sep 28 13:32:00 2021] 127.0.0.1:34722 Accepted
[Tue Sep 28 13:32:00 2021] 127.0.0.1:34722 [200]: GET /favicon.ico
[Tue Sep 28 13:32:00 2021] 127.0.0.1:34722 Closing

但是，如果我访问 localhost:8000，我会看到，这似乎是一个 Laravel 500 错误页面。所以我正在服务，这很好，但该应用程序并不是真正的运行ning。

我完成的安装步骤：

克隆源 coe 的 git 存储库并 cd 到项目根目录
安装 php、composer、npm（对于 javascript）并验证它们在我的系统上是否正常工作（我系统上的所有 return 有效版本）
运行 npm install、composer install 从项目根目录安装 composer.lock、package.lock 的内容，它们存在于项目根目录
php artisan serve 来自项目根目录

在我收到 500 服务器错误后，如果我查看日志（在 storage/logs/laravel.logs 中），我会发现以下堆栈跟踪：

我找到了一些参考资料，指出 php artisan key:generate 应该为我生成这样一个密钥并解决错误。但是，如果我运行最后一个命令，我会收到另一个错误：

我开始觉得我在上游遗漏了一些关键的东西。我应该在项目中有某种 .env 文件吗？ none 来自 git 仓库。可能是某些环境 files/variables 不存在？或者是否有额外的 artisan/composer 命令我需要运行ning 才能考虑启动它？

Answer 1

您的根目录中似乎没有 .env 文件。您需要创建一个可以从 .env.example.

复制的 .env 文件

之后你可以运行 php artisan key:generate 它应该可以正常工作。
