屢屢碰壁，安裝一個項目，發(fā)現(xiàn)沒有依賴，需要使用composer安裝，沒接觸過，找了網(wǎng)上也沒攻略，自己弄了后有以下問題，經(jīng)過調(diào)整解決了：
報錯1:沒有安裝fileinfo擴(kuò)展
Loading composer repositories with package information
Updating dependencies
Your requirements could not be resolved to an installable set of packages.Problem 1
– Root composer.json requires alipaysdk/easysdk 2.0 -> satisfiable by alipaysdk/easysdk[2.0.0].
– alipaysdk/easysdk 2.0.0 requires ext-fileinfo * -> it is missing from your system. Install or enable PHP's fileinfo extension.
Problem 2
– topthink/think-filesystem[v1.0.0, …, v1.0.3] require league/flysystem ^1.1.4 -> satisfiable by league/flysystem[1.1.4, …, 1.1.10].
– league/flysystem[1.1.0, …, 1.1.10] require ext-fileinfo * -> it is missing from your system. Install or enable PHP's fileinfo extension.
– Root composer.json requires topthink/think-filesystem ^1.0 -> satisfiable by topthink/think-filesystem[v1.0.0, v1.0.1, v1.0.2, v1.0.3].To enable extensions, verify that they are enabled in your .ini files:
– /www/server/php/82/etc/php.ini
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.
2、刪除禁用函數(shù)puv
3.其他報錯信息，請自己翻譯，整改好重新運行即可，我這里沒留存其他報錯信息了
成功安裝
