先说一下Yii框架PHP运行环境的情况。
Yii2.0.12版本使用\yii\base\Object类，Object作为类名PHP7.2报错。
PHP7.2的Yii2最小可用版本为2.0.13。
提供若干升级的方法。
- 项目使用Composer管理
bower和npm前端资源。
安装最新版composer-asset-plugin
composer global require "fxp/composer-asset-plugin"
指定类库更新
composer update yiisoft/yii2 yiisoft/yii2-composer bower-asset/jquery.inputmask
Composer记录如下
Loading composer repositories with package information
Updating dependencies (including require-dev)
Reading bower.json of bower-asset/yii2-pjax (2.0.7.1)GitHub API limit (60 calls/hr) is exhausted, could not fetch https://api.github.com/repos/yiisoft/jquery-pjax/commits/aef7b953107264f00234902a3880eb50dafc48be. Create a GitHub OAuth token to go over the API rate limit. You can also wait until 2019-02-15 18:54:52 for the rate limit to reset.
Head to https://github.com/settings/tokens/new?scopes=repo&description=Composer+on+bw-hz-dev-v14+2019-02-15+1755
to retrieve a token. It will be stored in "/data/home/wwwroot/.config/composer/auth.json" for future use by Composer.

- Updating yiisoft/yii2 (2.0.12 => 2.0.16): Loading from cache

Generating autoload files
- 项目配置不通过Composer管理
bower和npm的资源
如果你的Yii2做接口应用、微框架，不需要JS，CSS，或自行管理前端资源，在安装更新的时候可以移除对bower和npm的资源的依赖。
修改composer.json
"require" : {
"yiisoft/yii2": "2.0.16"
},
"replace": {
"bower-asset/inputmask": ">=3.2.0"
}
按需升级
composer update yiisoft/yii2 yiisoft/yii2-composer bower-asset/jquery.inputmask
如果有报错，一般都是前端资源依赖问题，移除即可。
