【新手】ionic搭建工程无法执行npm install

[季末晚风]

1. 本人完全按照ionic官网提供的方式安装了ionic的运行环境。
node@10.9.0
cordova@8.1.1
ionic@3.10.3 --因为最新的无法执行ionic start myApp 被我降了版本。
同时因为各种百度，还安装了：
python@2.7.3
.net.freemark.2.0 sdk
Microsoft Visual Studio 2013

2. 现在能够安全执行ionic start myApp，但是在npm install时出现：
> node-sass@4.5.3 install C:\Users\admin\Desktop\cordova\app1\node_modules\@ionic\app-scripts\node_modules\node-sass
> node scripts/install.js

> node-sass@4.5.3 postinstall C:\Users\admin\Desktop\cordova\app1\node_modules\@ionic\app-scripts\node_modules\node-sass

之后build时出现错误：
......
