安装npm组件时出现Python语法错误

Question

我正在尝试通过npm安装以下vue组件：

https://github.com/xwpongithub/vue-range-slider

我安装它的目的是：

npm install vue-range-component --save

但是，我在控制台中遇到以下错误：

> fsevents@1.2.11 install /Users/jovan/Desktop/work/projects/topgraphs/node_modules/fsevents
> node-gyp rebuild

+ vue-range-component@1.0.3

显然，该组件已经安装，但是Python中存在某种语法错误？在互联网上搜索解决方案时，我只找到了一些对不同Python版本的引用，但在上面的整个错误输出中没有提到版本。我正在使用Python 3.7

Answer 1

是的，给出的Python代码仅对python3之前的Python版本有效

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

在python3中print语句是一个函数，因此不能省略括号。应更新包以使用：

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

。。相反

Answer 2

语法

print "string"

在Python 3+中无效

您有Python3，但是库使用Python2.7，所以请安装Python2.7
