[cebe]

how did you manage to install yiisoft/yii2-apidoc without installing nikic/php-parser which is required by it: https://github.com/yiisoft/yii2-apidoc/blob/master/composer.json#L26 ?

[cebe]

can you also show your composer.json?

[wxs77577]

$cat composer.json
{
    "name": "root/yii2doc",
    "require": {
        "yiisoft/yii2-apidoc": "^2.0@dev"
    },
    "authors": [
        {
            "name": "xuesong",
            "email": "wu-xuesong@qq.com"
        }
    ],
    "minimum-stability": "dev"
}
