Question

我安装了yii2并编写了应用程序。我用git。当我将应用程序传输到服务器时。一切都很好看。但是当我尝试登录时，我收到了这条消息：

会出现什么问题？我跑了作曲家更新。为什么只缺少安全性？

Answer 1

您应该使用getSecurity（）

 Yii::$app->getSecurity()->generatePasswordHash($password);

Answer 2

好的，我发现了一个错误。运行composer update时。它更新了作曲家，但在安装手册中找到了你必须执行

composer global require＆＃34; fxp / composer-asset-plugin：~1.1.1＆＃34;

这个选项我忘了在新电脑上全新安装了。现在一切正常

Answer 3

这是否正确：警予:: $应用程序？

不应该是Yii :: app（）

我还不熟悉2.x。
