Composer 执行了 composer selfupdate 升级后 安装插件老报错了，求解？

"require": {
    "php": "^7.2",
    "barryvdh/laravel-ide-helper": "^2.8",
    "doctrine/dbal": "^2.12",
    "encore/laravel-admin": "1.8",
    "fideloper/proxy": "^4.0",
    "laravel/framework": "^6.0",
    "laravel/tinker": "^1.0",
    "overtrue/laravel-lang": "3.0.17",
    "overtrue/laravel-wechat": "5.1.0",
    "tymon/jwt-auth": "1.0.1"
}

不是提示很清楚了么，wechat包有问题。
