【问题描述】：

我用的是mac

我尝试运行我的第一个 ionic 项目，但在我的 mac 中运行它时遇到错误

我正在将我遵循的所有步骤放入终端 -

开始于 - : $ ionic start MyIonicProject 教程
$cd MyIonicProject
$ionic 服务

然后我收到错误

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.

? Install @ionic/app-scripts? Yes

【问题讨论】：

尝试使用“npm install”安装节点依赖项
我已经在应用程序中有 node_module 文件夹，你的这个解决方案对我没有帮助

【解决方案1】：

尝试通过附加sudo 来运行命令，如下所示：

sudo ionic serve

或者

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

【解决方案2】：

这个项目中似乎没有安装@ionic/app-scripts。

所以先试试这个：

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

然后：

npm install

和

ionic serve -l
