我正在使用Mac

我试图运行我的第一个离子项目，但是在Mac中运行它却遇到了错误

我将遵循的所有步骤放入终端-

从-开始：$ ionic开始MyIonicProject教程
$ cd MyIonicProject
$ ionic服务

然后我出错了

Error: EACCES: permission denied, open '/Users/user/.ionic/helper.log'
> ionic-app-scripts serve --address 0.0.0.0 --port 8100 --livereload-port 35729 --dev-logger-port 53703 --nobrowser

[INFO] Looks like @ionic/app-scripts isn't installed in this project.

       This package is required for this command to work properly.

Answer 1

尝试通过附加sudo来运行命令，如下所示：

sudo ionic serve

或

在终端窗口中运行以下命令：

sudo chown -R $USER /usr/local/

这将更改本地文件夹中所有内容的权限，然后尝试以下命令：

sudo ionic serve

Answer 2

该项目中未安装类似@ ionic / app-scripts的
。

所以请先尝试：

npm install @ionic/app-scripts@latest --save-dev

然后：

npm install

和

ionic serve -l
