[python] npm - "Can't find Python executable "python", you can set the PYTHON env variable."

I'm trying to run the following command: npm install -g bower gulp cordova ionic tsd@next karma-cli protractor node-gyp coffee-script js-beautify typescript npm-check

I have installed Python, Visual Studio Express and node-gyp so thought I'd be good to go, however I get the following errors:

Regarding the "Can't find Python executable "python", you can set the PYTHON env variable." error, I'm a little confused because I have set the PYTHON environmental variable like so:

Any ideas please?

One of the following solutions will work for you:

1. npm config set python c:\Python\27\python.exe or set PYTHON=D:\Python\bin\Python.exe
2. npm config set python D:\Library\Python\Python27\python.exe
3. Let npm configure everything for you (takes forever to complete) npm --add-python-to-path='true' --debug install --global windows-build-tools (Must be executed via "Run As Administrator" PowerShell)

If not... Try to install the required package on your own (I did so, and it was node-sass, after installing it manually, the whole npm install was successfully completed

The easiest way is to let NPM do everything for you,

npm --add-python-to-path='true' --debug install --global windows-build-tools

I installed python2.7 to solve this issue. I wish can help you.

https://github.com/nodejs/node-gyp#on-windows

https://github.com/Microsoft/nodejs-guidelines/blob/master/windows-environment.md#environment-setup-and-configuration

try

npm config set python D:\Library\Python\Python27\python.exe

Just run below command with admin access

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

Try:

Install all the required tools and configurations using Microsoft's windows-build-tools by running npm install -g windows-build-tools from an elevated PowerShell (run as Administrator).

You are running the Command Prompt as an admin. You have only defined PYTHON for your user. You need to define it in the bottom "System variables" section.

Also, you should only point the variable to the folder, not directly to the executable.
