升級node.js和離子後離子服務器不工作

Question

我升級了node.js和npm，並執行了npm安裝，現在我得到下面的消息。問題是，我一直在應用程序上工作大約一年，安裝了gulp-sass（這是我用來升級我的sass文件），所以顯然是升級，但我不知道如何獲得一切再次開始，再次降級一切。

$ ionic serve 
Uh oh! Looks like you're missing a module in your gulpfile: 
Cannot find module 'gulp-sass' 

Do you need to run `npm install`? 

當我嘗試npm install gulp-sass：

我發現了離子論壇問題的解答，相關部分下方是爲了清楚起見，一些修改：

只需添加到您的gulpfile.js

gulp.task('serve:before', ['default']); 

這條線告訴新的離子2客戶端運行舊的離子1.x客戶端 「默認」任務之前（運行離子發球之前）

此外，您需要添加您的ionic.config.json文件：

{ 
    ... 
    "app_id": "", 
    "v2": false, 
    "typescript": false, 
    "watch": { 
    "sass": ["scss/**/*.scss"], 
    "html": ["www/**/*.html"], 
    "livereload": [ 
     "www/**/*.html", 
     "www/**/*.js", 
     "www/**/*.css" 
    ] 
    } 
    ... 
}

我以前遇到過這個問題。我到目前爲止所嘗試的：

1. 重新安裝node.js.你可以參考在命令行https://nodejs.org/en/download/
2. 運行：npm rebuild node-sass

然後試試運行ionic serve。希望它可以幫助你。
