在linux manjaro上安装gulp-sass时出错

Question

当我尝试安装gulp sass时，我得到了很多错误。我最近从我的windows机器切换到我的linux机器，在windows上它工作得很好。现在，当我尝试安装gulp (npm install gulp)时，它工作得很好。但是当我在那之后尝试安装gulp sass (npm install gulp-sass)时，我得到了一大堆错误。

Answer 1

从你的日志中：

python2 Error: not found: python2

node-gyp找不到python，因此它会返回到/usr/bin/ python2，它将是python3。

然后：

import sys; print "%s.%s.%s" % sys.version_info[:3];

python3中的“print”语法已更改，因此不再有效。

安装Python2，你就可以解决这个错误。
