ionic-framework - 我在运行 Ionic 应用程序时遇到错误

Question

在我的 Mac 中运行命令>sudo ionic serve后，我得到 -：

ionic-app-scripts 服务 --address 0.0.0.0 --port 8100 --livereload-port 35729 --dev-logger-port 53703 --nobrowser

[INFO] 看起来这个项目中没有安装@ionic/app-scripts。

   This package is required for this command to work properly.

? 安装@ionic/app-scripts？是的

当我开始使用 cli command > npm i -D -E @ionic/app-scripts安装它时， 我得到-：

npm WARN deprecated hoek@2.16.3: The major version is no longer supported. Please update to 4.x or newer

正如您在上面看到的，我收到了错误，我将上面代码的一些错误部分放在下面，请查看：

您收到“EACCESS”错误，这可能与权限不足有关。尝试像这样更改项目目录的所有者：

sudo chown -R user:user /Users/user/Projects/MyIonicProject

然后：

npm i -D -E @ionic/app-scripts
