Scott Frees' solution didn't work for me but running

npm config set python $(which python)

did.

    For me the path was slightly different. Be sure to check `which python` to get the path before setting it with npm config. – Petr Gazarov Dec 25 '16 at 22:40

If you installed Python using a package manager, it should already be on your path- but if not: add it like this:

export PATH="$PATH:/usr/local/bin/python (or wherever you installed python to)

Node-gyp requires 2.x and cannot use Python3 (do you have the right version installed?).

See Running Python on Windows for Node.js dependencies for Windows to make sure you have your environment variable set.

  • actually i'm using ubantu 14.04 – SudTheNerd Jan 03 '16 at 19:22
  • Right - the export PATH="$PATH:/usr/local/bin/python is for Linux. It sounds like Python is not on your path - wherever you installed it to needs to be added to the PATH. – Scott Frees Jan 04 '16 at 01:41
  • Using pyenv, I needed to add this (from the suggestion from https://stackoverflow.com/a/71620699/4597676): ```export PYENV_ROOT="$HOME/.pyenv" export PATH="$PYENV_ROOT/shims:${PATH}"``` – Mugshep Jul 05 '22 at 14:11

I solved a similar error by upgrading the node-sass package to a version that is compatible with my installed Node version.

node-sass publishes a compatibility table that I found on their NPM page.
