找不到模块node_modules\@ionic\app-scripts IONIC 3

我已经安装了npm 3.10.10那么我有installed ionic 3.9.2 and cordova 7.0.1.

我尝试了以下步骤：

1. ionic start newProject

   （选择一个选项卡项目）

2. ionic serve

该命令将throw the error

错误：找不到模块 'E:\firstProject\node_modules\@ionic\app-scripts'

我只找到这个线程错误：找不到模块“@ionic/app-scripts” https://stackoverflow.com/questions/44381358/error-cannot-find-module-ionic-app-scripts.

我不想降级我的nodejs版本，因为我想使用最新功能

但我尝试过，

npm i @ionic/app-scripts (演员工会答案)

我也一样error执行上面之后command

请帮助我而不降级nodejs version

编辑1（根据 sampath 建议）：下面是我的package.json file

当我跑步时ionic info它给出了某种错误

$ 离子信息

编辑2：（在 sampath 回答之后）

1. 我做了以下更改

i removed `"@ionic/app-scripts": "2.1.4"`

2. $ npm install @ionic/app-scripts@latest --save-dev

发布 $ npm install @ionic/app-scripts@latest --save-dev ， package.json 文件如下所示

请帮助我提前谢谢！！！！

伙计们，我解决了这个问题。只是想与您分享，至少节省您的时间。按照步骤进行。

1. Remove node_modules.
2. 将节点降级到版本 6（运行npm install node@6 or brew install node@6)
3. Add "@ionic/app-scripts": "3.1.9"在依赖项下project.json
4. npm i
