1、創建vue項目后安裝less，執行 npm install less less-loader --save-dev
下載版本為：less-loader@6.1.0 ， less@3.11.3，重啟服務報錯，報錯信息如下：
2、報錯原因 less 本版太高需要降低版本，執行代碼
先移除之前版本：
npm uninstall less-loader
下載指定版本：
npm install less-loader@5.0.0 -D
3、重啟代碼就可以了，若還是報錯可移除文件node_modules，重新下載cnpm install
補充知識：vue項目運行報錯：94% asset optimization ERROR Failed to compile with 2 errors13:03:01 error in ./src/ba
使用vue編寫的前端項目運行報錯：
88% hashing
89% module assets processing
90% chunk assets processing

出錯原因就是sass不支持當前的環境，那么在當前環境重新安裝一下就好了
1、查看本地nodejs的版本號和node-sass的版本號
node -v ---查看nodejs的版本號以及查看其是否安裝
node-sass -v ---查看node-sass的版本號以及查看其是否安裝
2.、卸載node-sass，但是如果卸載不成功，直接找到node-sass文件夾，刪除
npm uninstall --save node-sass --記住執行這個命令前，需要先進入到對應的文件目錄才可以刪除
如圖（如下圖即可）：
3、重新安裝更新版本的node-sass即可
npm install --save node-sass (cnpm install --save node-sass )
（這個也要在指定文件夾執行，并進行本地安裝）
這樣就可以了！！！！！！！！！
如下圖所示：
以上這篇解決vue安裝less報錯Failed to compile with 1 errors的問題就是小編分享給大家的全部內容了，希望能給大家一個參考，也希望大家多多支持服務器之家。
