最近在开发vue项目，执行npm install时，出现了关于python的相关错误，如下：
Binary found at D:IdeaProjectsgykj-map-corenode_modulesnode-sassvendorwin32-x64-83binding.node
Testing binary
Binary has a problem: Error: \?D:IdeaProjectsgykj-map-corenode_modulesnode-sassvendorwin32-x64-83binding.node is not a valid Win32 application.

原因
这个是因为node-sass模型需要在本机进行编译，编译的时候，需要python2的环境，如果它无法获取到Python的路径的话，就会报这个错误。以本人电脑为例，我电脑上同时存在python2和python3的环境，导致无法识别了。
解决办法如果你电脑上已经安装过python2的环境，可以执行下面的代码，配置python路径，注意这个路径一定要是python.exe文件，所在的目录。
npm config set python C:Python27
我的电脑上安装了ArcGIS，使用的是它自带的python环境，我电脑上的路径是C:Python27ArcGIS10.8。
然后删除依赖，重新安装依赖，上面的问题就消失了。
rimraf node_modules npm install
