Question

我在 Windows Server 20012 R2 上遇到了作曲家的问题。我正在尝试部署网站，每次运行composer install或composer update时，我都会收到以下信息：

$ composer install
Loading composer repositories with package information
Installing dependencies (including require-dev) from lock file
Nothing to install or update
Generating autoload files
> Illuminate\Foundation\ComposerScripts::postInstall
> php artisan optimize
Script php artisan optimize handling the post-install-cmd event returned with an error


  [RuntimeException]
  Error Output:


install [--prefer-source] [--prefer-dist] [--dry-run] [--dev] [--no-dev] [--no-custom-installers] [--no-autoloader] [--no-scripts] [--no-progress] [-v|vv|vvv|--verbose] [-o|--optimize-autoloader] [-a|--classmap-authoritative] [--ignore-platform-reqs] [--] [<packages>]...

当我检查 php错误日志时，我发现以下内容：

[17-Jul-2016 08:04:58 UTC] PHP Fatal error:  Uncaught exception 'ReflectionException' with message 'Class log does not exist' in C:\PATH_TO_PROJECT\vendor\laravel\framework\src\Illuminate\Container\Container.php:734
Stack trace:

#4 C:\PATH_TO_PROJECT\vendor\laravel\framework\src\Illuminate\ in C:\PATH_TO_PROJECT\vendor\laravel\framework\src\Illuminate\Container\Container.php on line 734

当我在 Ubuntu服务器上尝试相同项目时，一切正常！我试过在互联网上找到的每一个答案，但没有任何对我有用。有关如何解决此问题的任何建议？为什么会这样？

Windows服务器PHP版本为5.6。

Answer 1

我能够通过删除 .env 文件中值中的任何空格来解决此问题，例如：

MAIL_PORT= 587
MAIL_FROM_NAME=ABC Medical

为：

MAIL_PORT=587
MAIL_FROM_NAME=ABCMedical

或使用引号：

MAIL_PORT=587
MAIL_FROM_NAME="ABC Medical"

Answer 2

我在.env中没有引号的空格中传递值时出现此错误，我通过将值包装在引号中来修复它。

Answer 3

你尝试过吗？ composer dump-autoload？

你可以添加一个没有dump-autoload

的类

Answer 4

我可以想到发生此错误的最常见原因如下：

在USE语句中未包含日志类的范围内调用日志类。
配置文件包含（解析）错误，而这些错误又不允许您的应用程序找到Log类。检查Laravel中早期加载的文件，例如app.php。

如何修复未捕获的异常'ReflectionException'消息'类日志不存在'？
