Some styles written by sass are used in the project, but errors are reported every time they are compiled

According to the above reminder, NPM rebuild node sass — force is still wrong. But looking at his error message carefully, I found this one:

gyp verb could not find “C:\Users\myh\AppData\Local\Programs\Python\Python36\python.EXE”. checking python launcher
gyp verb could not find “C:\Users\myh\AppData\Local\Programs\Python\Python36\python.EXE”. guessing location
gyp verb ensuring that file exists: C:\Python27\python.exe
gyp ERR! configure error
gyp ERR! stack Error: Can’t find Python executable “C:\Users\myh\AppData\Local\Programs\Python\Python36\python.EXE”, you can set the PYTHON env variable.

Ha ha, now I know. That is to say, I don’t have Python environment variables locally. Is this node sass written in Python

With doubts, I downloaded the latest Python installation, and then configured the following environment variables according to the above:

Then, with an uneasy mood, knock down: NPM install node sass — save  

Yes, installation succeeded

continue to compile the development environment, and the compilation is successful
