vue項目用npm安裝sass包遇到的問題及解決辦法

 

IDEA啓動vue程序，瀏覽器訪問時出現以下狀況的關於node-sass的錯誤：

錯誤1：

Module build failed (from ./node_modules/sass-loader/dist/cjs.js)

Error:Cannot find module 'node-sass'

錯誤2：

Module build failed (from ./node_modules/sass-loader/dist/cjs.js)

Error:no such file or directory, open 'D:\SourceProject\sichebangong\car-pub-vue\node_modules\node-sass\lib\index.js'

 

 

Failed to compile.

查看項目的node_modules目錄，有sass-loader，卻沒有node-sass。

安裝sass吧。命令：npm install node-sass -g

提示了好多錯誤，如

Cannot download "https://github.com/sass/node-sass/releases/download/v4.13.0/win32-x64-72_binding.node"， 緣由是sockettimedout。

MSBUILD : error MSB4132: 沒法識別工具版本「2.0」。可用的工具版本爲 "4.0"

npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for fsevents@2.1.2: wanted {"os":"darwin","arch":"any"} (current: {"os":"win32","arch":"x64"})

python

 

網上資料有不少，不過每一個人的狀況不同，因此，並無解決個人問題。

最終解決辦法是使用cnpm命令

cnpm uninstall node-sass
cnpm install node-sass

成功安裝sass包。
