  Problem 1
    - magento/inventory-composer-installer 1.1.0 requires composer-plugin-api ^1.1 -> found composer-plugin-api[2.6.0] but it does not match the constraint.
    - magento/product-community-edition 2.3.3 requires magento/inventory-composer-metapackage 1.1.3 -> satisfiable by magento/inventory-composer-metapackage[1.1.3].
    - magento/inventory-composer-metapackage 1.1.3 requires magento/inventory-composer-installer 1.1.0 -> satisfiable by magento/inventory-composer-installer[1.1.0].
    - Root composer.json requires magento/product-community-edition 2.3.3 -> satisfiable by magento/product-community-edition[2.3.3].

军哥，请问请问如何降低compoer版本？从版本 2.3.3降到版本 1.1.0？
谢谢。
