离子发球失败的离子2 rc0应用

Question

我刚刚创建了一个新的Ionic 2 rc0应用程序,我昨晚能够运行它.

但是,在离子服务器运行后将计算机置于睡眠状态后,在关闭离子服务器后立即尝试启动应用程序会产生此错误:

Running 'serve:before' npm script before serve
> ionic-hello-world@ watch J:\ionic projects\newionicapp
> ionic-app-scripts watch
module.js:457
    throw err;
    ^

Mind letting us know? https://github.com/driftyco/ionic-cli/issues

如果我创建一个新的应用程序,它运行正常.所以我认为我的项目中存在某些问题.但我不知道是什么.

Answer 1

删除node_modules文件夹,然后运行npm install以重新安装所有模块.这将确保所有节点模块都是干净的.

同时删除www文件夹的内容,然后运行ionic serve重新生成文件.这将确保您的项目构建是干净的.

如果这不起作用,请尝试通过运行将ionic-cli更新到最新版本,npm install -g ionic@2.1.0然后再次尝试上述操作.

Ionic CLI使用的离子应用程序脚本版本不是特定的目标版本.Ionic-app-scripts已经更新,虽然离子cli还没有,它现在使用了更新版本的ionic-app-scripts,这给我带来了一些问题.

祝好运!

Answer 2

尝试更新离子应用程序脚本.

npm i @ionic/app-scripts

它对我有用.
