有必要执行以下操作：
composer self-update
composer global require "fxp/composer-asset-plugin:*"
但是在执行编辑器自我更新后，会弹出一个错误：
The "hirak/prestissimo" plugin was skipped because it requires a Plugin API version ("~1.0.0-alpha10") that does not match your Composer installation ("1.1.0"). You may need to run composer update with the "--no-plugins" option.
我当前的Composer版本是1.4.2 出于同样的原因，以下命令不起作用：
composer global require "fxp/composer-asset-plugin:*"
弹出错误：
The "hirak/prestissimo" plugin was skipped because it requires a Plugin API version ("~1.0.0-alpha10") that does not match your Composer installation ("1.1.0"). You may need to run composer update with the "--no-plugins" option.
如何获得所需版本的Composer Plugin API？
答案 0 :(得分：1)
您只需要更新hirak/prestissimo：
composer global update hirak/prestissimo --no-plugins
