应用程序脚本库损坏了我的 Ionic 配置

Question

我尝试安装应用程序脚本，但出现此错误。它搞砸了我的环境，我不能再使用ionic serve了。

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

Answer 1

看起来您有一个UNMET PEER DEPENDENCY尝试将打字稿固定到package.json中的兼容版本。

@ionic/app-scripts@1.2.1 需要 typescript@~2.2.1 的对等体，但没有安装任何对等体。

尝试在固定版本后执行以下命令，以确保重新安装node_modules rm -rf node_modules && npm cache clean && npm install

Answer 2

npm install app-scripts@1.1.4 --save-dev 

解决了。
