javascript - Node.js (npm) refuses to find python even after %PYTHON% has been set

Question

So I am trying to get the Node.js to work. Of course, it's not as easy as advertised :)

I happen to have two python versions on my computer, but Node.js seems to only work with the older one, 2.7. Upon error, it also encourages me to set the path into PYTHON environment variable with this error:

Error: Can't find Python executable "python2.7", you can set the PYTHON env variable.

Ok then, I configured the variable as desired:

C:UsersJakub>set PYTHON=C:MYSELFProgramsPython2.7python.exe

C:UsersJakub>echo %PYTHON%
C:MYSELFProgramsPython2.7python.exe

You can see that I used echo to check whether the variable was really set. Unfortunatelly, that npm thing can't read it and the error appears again. Here's the full log right after I set the %PYTHON% variable:

C:UsersJakub>npm install minecraft-protocol

I figured out the most stable solution is to set python npm internal value to actual path:

npm config set python C:ProgramsPython2.7python2.7.exe

This skips all environment variable and %PATH% crap and just starts the python wherever it's installed.
