The complete name should match “[a-z0-9]([_.-]?[a-z0-9]+)*/[a-z0-9]([_.-]?[a-z0-9]+)*”. Make sure you fix this as Composer 2.0 will error.

Deprecation warning: Your package name base is invalid, 
it should have a vendor name, a forward slash, and a package name. 
The vendor and package name can be words separated by -, . or _. 
The complete name should match "a-z0-9/a-z0-9". 
Make sure you fix this as Composer 2.0 will error.

原因

其中name属性为base，不符合composer的命名规范（一个vendor名+ / +包名）组成，全名必须和“a-z0-9/a-z0-9”正则匹配，在Composer2.0里将会属于错误。

解决

将包名改为符合规则的形式1

“name”: “somename/base”,
“description”: “System with Yaf.”,
“license”: “BSD-3-Clause”,
“type”: “project”,
“keywords”: [
