安裝node-sass及報錯後解決方案

使用npm install 命令安裝node-sass時，常常出現安裝失敗的狀況。緣由在於npm服務器在美國，還有就是某強大的防火牆做用。致使模塊沒法下載。

1 npm install node-sass                                                      

1 Cannot download https://github.com/sass/node-sass/releases/download/v3.4.2/win32-x64-46_binding.node
2 
3 Hint: If github.com is not accessible in your location
4 try setting a proxy via HTTP_PROXY, e.g. 
5 export HTTP_PROXY=http://example.com:1234
6 or configure npm proxy via
7 npm config set proxy http://example.com:8080'

 

解決方法：
一、使用淘寶鏡像完成安裝。

1 npm install -g cnpm --registry=https://registry.npm.taobao.org
2 cnpm install node-sass

 

在安裝node-sass以後，從新運行會報以下錯誤

ERROR Failed to compile with 1 errors 16:47:39

This dependency was not found:

* !!vue-style-loader!css-loader?{"sourceMap":true}!../../node_modules/vue-loader/lib/style-compiler/index?{"vue":true,"id":"data-v-742a2c37","scoped":true,"has
InlineConfig":false}!sass-loader?{"sourceMap":true}!../../node_modules/vue-loader/lib/selector?type=styles&index=0!./signInBg.vue in ./src/components/signInBg.
vue

To install it, you can run: npm install --save !!vue-style-loader!css-loader?{"sourceMap":true}!../../node_modules/vue-loader/lib/style-compiler/index?{"vue":t
rue,"id":"data-v-742a2c37","scoped":true,"hasInlineConfig":false}!sass-loader?{"sourceMap":true}!../../node_modules/vue-loader/lib/selector?type=styles&index=0
!./signInBg.vue

解決思路：

1. npm install sass-loader --save;

2. npm install node-sass --save;

而後運行npm run dev就能夠
