  • 重点是我本地已经安装了Python了 ，DOS命令下是执行python，输出如下：

C:\Users\Administrator>python
Python 3.6.1 (v3.6.1:69c0db5, Mar 21 2017, 18:41:36) [MSC v.1900 64 bit (AMD64)]

回答：

表示node-sass并不需要python2...
我特意把环境变量清空，把python和node都删除，重新安装了python3.6.1(64x)和nodejsv6.10.2然后用cnpm install node-sass --save-dev就直接装上并且可以正常编译sassscss了。。

node-sass是4.5.2，直接cnpm就安装成功了

回答：

node-sass编译需要python2

你装的是python3

回答：

这个考虑两方面：
1、py及其版本
2、墙

回答：

1.安装python2.7

2.npm rebuild node-sass

回答：

问题已解决

  1. Python3和Python2确实有版本差异，删除3后安装2（python-2.7.6.msi）

  2. cnpm install node-sass --save-dev

回答：

我把python卸载了重新 npm i 就行,
好像有python的情况下会用python编译一些东西,没有的话就直接下载dist的,不会编译.然后就好了

以上是 win7 install node-sass出错，提示not found: python2 的全部内容， 来源链接： utcz.com/a/148642.html
