离子 - 错误：找不到模块'gulp-sass'

Question

我有一个 Ionic v1 应用程序，当我尝试通过 gulp 命令运行该应用程序时，我收到以下错误：

Error: Cannot find module 'gulp-sass' from '/Users/bertcarremans/Tuintalent/code'
at Function.module.exports [as sync] (/Users/bertcarremans/Tuintalent/code/node_modules/resolve/lib/sync.js:40:15)

at apply (/Users/bertcarremans/Tuintalent/code/node_modules/thunks/index.js:355:38)

所以我按照post 中提到的说明操作并尝试了npm update 但后来我收到以下错误：

我的这个应用程序的环境是： cli 包：(/usr/local/lib/node_modules)

@ionic/cli-utils  : 1.19.1
ionic (Ionic CLI) : 3.19.1

全局包：

cordova (Cordova CLI) : 8.0.0 
Gulp CLI              : CLI version 3.9.1 Local version 3.9.1

本地包：

Cordova Platforms : android 7.0.0 ios 4.5.4
Ionic Framework   : ionic1 1.3.2

系统：

ios-deploy : 1.9.0 
ios-sim    : 6.1.2 
Node       : v8.9.4
npm        : 5.6.0 
OS         : macOS Sierra
Xcode      : Xcode 9.2 Build version 9C40b 

环境变量：

ANDROID_HOME : not set

杂项：

backend : pro

删除node_modules 并执行npm install 也会产生其他错误。

有人知道如何解决这个问题吗？谢谢！

Answer 1

只需在您的根文件夹中执行npm update 然后npm install gulp-sass --save-dev，然后在运行时您应该不会有任何问题。

或者做

rm -rf node_modules/
npm install

对于 OP 来说已经很晚了——但是，node-gyp make 错误意味着“节点正在编译模块的 c/c++ 的本机代码并且失败了”——在我最近遇到的类似情况下，MacOS 构建工具无效，可以当 XCODE 更新但命令行工具（c++ 编译器等）尚未准备好使用时导致。

对于 MacOS 上 node-gyp 问题的典型解决方案，该模块有不错的文档 - MacOS node-gyp fixes
