尝试作曲家更新时，在 CentOs 上出现此错误

Question

我正在尝试在 CentOs 系统上部署我的 laravel 项目。当我要运行作曲家更新命令时，我遇到了此错误。我无法找出解决方案，我在这个平台上搜索了解决方案。我找到了 Windows，但在我的 CentOs 系统上不起作用。

Windows 解决方案：

我打算在 php.ini 文件中添加这一行：

extension=php_fileinfo.dll

但没有用。

错误信息；

    - laravel/framework[v8.12.0, ..., 8.x-dev] require league/flysystem ^1.1 -> satisfiable by league/flysystem[1.1.0, ..., 1.x-dev].
    - league/flysystem[1.1.0, ..., 1.x-dev] require ext-fileinfo * -> it is missing from your system. Install or enable PHP's fileinfo extension.

To enable extensions, verify that they are enabled in your .ini files:

You can also run `php --ini` in a terminal to see which files are used by PHP in CLI mode.
Alternatively, you can run Composer with `--ignore-platform-req=ext-fileinfo` to temporarily ignore these required extensions.

Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.

Answer 1

您所需的软件包之一需要在 CentOs 系统中具有特定的 php 扩展。

查看composer update抛出的第二行错误消息

- league/flysystem[1.1.0, ..., 1.x-dev] 
 require ext-fileinfo * -> it is missing from your system. 
 Install or enable PHP's fileinfo extension.

请通过在 CentOs php.ini 中取消注释来启用这个缺失的 php 扩展

缺少的扩展名是 ext-fileinfo

注意：在新环境中部署项目时运行“composer install”也是一个好主意，以尽量减少突然更新的软件包版本可能引发安装问题。 另外不要忘记上传您的composer.lock。 看看这里的文档： https://laravel.com/docs/9.x/deployment#autoloader-optimization

我又遇到了这个问题，解决方法如下：

在WHM面板中通过EasyApache安装文件信息扩展和其他必要的软件包后，我的问题完全解决了。谢谢大家。
