蜻蜓短视频系统-文件上传之本地上传报错问题解决-蜻蜓Q蜻蜓s蜻蜓系统上传采用本地上传报错
蜻蜓系统有本地上传方式和云储存上传方式，云方式比较常用是不会有错的，本地上传方式可能会遇到这样的报错。
报错1
Class ‘League\Flysystem\Adapter\Local‘ not found
解决为：
安装Flysystem：
composer require league/flysystem
如安装继续提示报错：
报错2
[ErrorException]
pcntl_signal() has been disabled for security reasons
pcntl_signal函数被禁用，打开它。
宝塔直接在禁用函数中删除：
完事儿继续composer require league/flysystem
报错3
接下来可能会
Allowed memory size of 1610612736 bytes exhausted (tried to allocate 67108872 bytes) in phar:///usr/bin/composer/src/Composer/DependencyResolver/RuleSet.php on line 83
原因是内存不够，打开 php.ini 配置 ， memory_limit 配置项
将
memory_limit=128M 改为 -1
完事儿继续composer require league/flysystem
提示这样以后基本就ok了
如果还有报错
执行
composer self-update
如果提示
那么继续执行
composer require league/flysystem
如果报错如下：
Problem 1
- intervention/image is locked to version 2.5.1 and an update of this package was not requested.
- intervention/image 2.5.1 requires ext-fileinfo * -> it is missing from your system. Install or enable PHP’s fileinfo extension.
Problem 2
- laravel/framework is locked to version v6.18.20 and an update of this package was not requested.
- laravel/framework v6.18.20 requires league/flysystem ^1.0.34 -> found league/flysystem[1.0.34, …, 1.x-dev] but it conflicts with your root composer.json require (^2.3).
Problem 3
- laravel/framework v6.18.20 requires league/flysystem ^1.0.34 -> found league/flysystem[1.0.34, …, 1.x-dev] but it conflicts with your root composer.json require (^2.3).
- facade/ignition 1.16.1 requires illuminate/support ~5.5.0 || ~5.6.0 || ~5.7.0 || ~5.8.0 || ^6.0 -> satisfiable by laravel/framework[v6.18.20].
- facade/ignition is locked to version 1.16.1 and an update of this package was not requested.
To enable extensions, verify that they are enabled in your .ini files:
- /www/server/php/73/etc/php.ini
You can also run php --ini inside terminal to see which files are used by PHP in CLI mode.
Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.
You can also try re-running composer require with an explicit version constraint, e.g. “composer require league/flysystem:*” to figure out if any version is installable, or “composer require league/flysystem:^2.1” if you know which you need.
那么 继续解决：
先在配置中打开fileinfo 扩展，并且重启PHP服务，再次执行会发现少了一个问题
继续 后面2个问题。
又经过了各种折腾，最终得出，就是版本问题。
执行
composer require league/flysystem:*
解决问题。
现在我们来上传一个视频测试：
上传成功，不过这里还有一个错误是关于 缩略图裁剪失败。
本部分原因是我们禁用了ffmpg的裁剪部分，
需要开启 需要安装ffmpg ，但是 友情提示，目前因为已经依赖了composer的 这个上传依赖，如果再去用ffmpg可能会有未知问题。
YYC松鼠短视频系统 采用ffmpg 未采用composer 可正常使用，并且使用转码和打水印功能。
