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，并且在 windows 上它工作得非常好。现在，当我尝试安装 gulp (npm install gulp) 时，它工作正常。但是当我尝试安装 gulp-sass (npm install gulp-sass) 之后，我得到了很多错误。

来自您的日志：

python2 Error: not found: python2

node-gyp 找不到 python2，所以它回退到 /usr/bin/python 这将是 python3。

然后：

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

python3 中的“打印”语法已更改，因此不再有效。

安装 Python2，您将解决此错误。
