reason: in the project dependency package, the node-sass module requires node-gyp
and node-gyp; It also needs to rely on Python 2.7 and Microsoft’s VC + + build tools for compilation, but Windows operating system will not install Python 2.7 and VC + + build tools by default

Solution:
1. Use the administrator to open CMD

2. Install node-gyp
command

npm install -g node-gyp

3. Configure and install python2.7 and VC + + build tools
because node-gyp needs to rely on python2.7 and Microsoft’s VC + + build tools for compilation, but Windows operating system will not install python2.7 and VC + + build tools by default

Install python2.7 and VC + + build tools dependencies for node-gyp configuration:

npm install --global --production windows-build-tools

4. Check whether the installation is successful and restart NPM install
