PHP Strict Warning 'yiibaseErrorException' with message 'Declaration of m14050 1_075311_add_oauth2_server::primaryKey() should be compatible with yiidbMigrat ion::primaryKey($length = NULL)'
1、REST API application with OAuth2 server on Yii2的地址：https://github.com/ikaras/yii2-oauth2-rest-template
2、运行命令：php application/api/yiic migrate –migrationPath=@vendor/filsh/yii2-oauth2-server/migrations –interactive=0 \ 出错：
PHP Strict Warning ‘yii\base\ErrorException’ with message ‘Declaration of m14050
1_075311_add_oauth2_server::primaryKey() should be compatible with yii\db\Migrat
ion::primaryKey($length = NULL)’
3、修改文件：\yii2-oauth2-rest-template\vendor\filsh\yii2-oauth2-server\migrations\m140501_075311_add_oauth2_server.php
Need set Null on default in primaryKey function public function primaryKey($columns = null) or rename function
4、再次运行命令：php application/api/yiic migrate –migrationPath=@vendor/filsh/yii2-oauth2-server/migrations –interactive=0 \ ，正常运行：
