1、Warning: This development build of composer is over 60 days old. It is recommended to update it by running "C:\ProgramData\ComposerSetup\bin\composer.phar self-update" to get the latest version.
The "yiisoft/yii2-composer" plugin was skipped because it requires a Plugin API version ("1.0.0") that does not match your Composer installation ("1.1.0"). You may need to run composer update with the "--no-plugins" option.
composer selfupdate --no-plugins
