更新后出现离子发球错误 [英] Ionic serve error after updating

问题描述

我正在构建一个应用程序，它即将完成，在更新为ionic 2时，它开始给我这个错误:

I am building a app and its near its completion, upon updating to ionic 2 it started to give me this bug:

/Users/Raz/Work/Ionic 2/My-World/node_modules/.bin/ionic-app-scripts: line 1: ../@ionic/app-scripts/bin/ionic-app-scripts.js: No such file or directory

    npm ERR! There is likely additional logging output above.

    npm ERR! Please include the following file with any support request:

    There was an error serving your Ionic application: There was an error with the spawned command: serve

我更新了Npm，node和cordova，但仍然存在问题:

I updated Npm,node,and cordova and still there are problems:

Cordova CLI: 6.1.1 
Ionic Framework Version: 2.0.0
Ionic CLI Version: 2.2.1
Ionic App Lib Version: 2.2.0
Ionic App Scripts Version: 1.0.0
ios-deploy version: 1.9.0 
ios-sim version: 5.0.8 
OS: macOS Sierra
Node Version: v7.4.0
Xcode version: Xcode 8.1 Build version 8B62

我在其他机器上也做了同样的事情，结果也一样，看来问题可能出在离子本身而不是npm

I also did the same on other machine and the results are the same, it seems the problem could be with ionic itself and not with npm

推荐答案

尝试清除项目中的node_modules文件夹.

Try clearing your node_modules folder in your project.

运行npm install

这是解决大多数package.json更改问题的第一步.

It is the first step to fixing most issues with changes in package.json.
