使用npm安裝node-sass時(shí)，或者安裝需要python2的依賴時(shí)，會報(bào)出以下錯(cuò)誤。

復(fù)制代碼

解決方案一:

1. 安裝python2

• 可以用npm命令安裝

npm install -g node-gyp 
復(fù)制代碼

• 也可以自行下載安裝 Python 2.7

2. 安裝完畢后配置環(huán)境變量

npm config set python python2.7
復(fù)制代碼

3.再配置一下版本

npm config set msvs_version 2017
復(fù)制代碼

修改完畢，之后就可以正常安裝node-sass了，如果還不行就使用淘寶鏡像。

解決方案二(推薦)

node-sass實(shí)在太坑了，之前遇到安裝失敗使用方法一完美解決。最近又一次遇到了，但是方法一又無效了。于是我又在網(wǎng)上找到另一個(gè)方法，就是用dart-sass來替換node-sass。

正常的替換也會出問題，還要改配置。使用以下方法便可以解決 yarn安裝的:

yarn add node-sass@yarn:dart-sass -D
復(fù)制代碼

npm安裝的:文章來源地址http://www.zghlxwxcb.cn/news/detail-538241.html

yarn add node-sass@npm:dart-sass -D
