composer install报错You are using Composer 2, which some of your plugins

最近在github上找到一个开源的导航项目

首先git clone

然后执行`composer install`时出错

提示 You are using Composer 2, which some of your plugins seem to be incompatible with.

于是百度一下

执行以下命令

`composer self-update --1` 回滚至v1

然后再执行

`composer install`则可正确执行
