更新时 提示 "topthink/think-installer" plugin was skipped because it requires a Plugin API version ("^1.0") that does not match your Composer installation ("2.1.0")

订单系统所用扩展的topthink版本是 2.0.0  如果直接 composer update topthink/think-installer 扩展不兼容, 导致项目直接开不了.

处理

composer update topthink/think-installer  --no-plugins

更新之后  版本没有直接升级到 2.1 而是上升到了 2.0.5

然后再安装mongodb扩展

composer require topthink/think-mongo=1.*

因为php版本是7.2 所以mongo只能是1.*版本的

./composer.json has been updated
Running composer update topthink/think-mongo
