Node-gyp: ImportError: No module named compiler.ast on embedded linux

[danielloczi]

Hi! I tried to install mutliple npm packages (i2c-bus, i2c, ioctl) on linux, but all of them failed. I narrowed down the issue to node-gyp rebuild command. If I downloaded the source of i2c-bus and tried to run node-gyp rebuild it also failed.

• Compiler: gcc version 7.3.0 (GCC)
• Module: npm install i2c-bus, npm install i2c, npm install ioctl

This is an old issue, but I recently experienced the same. Turned out that the distribution (debian on pine64, don't remember which flavor if there are many) had python-minimal package installed, installing python2.7 fixed the problem.

Ah, I love the smell of Python installs to run JavaScript.

seems like it's a python installation problem
we should have python3 support soon too which may help resolve things like this

As far as I understand, when I install node in Ubuntu (using curl... etc., as recommended by Node), it installs python2.7-minimal, and the package does not include ast module. I have installed python-2.7 package to solve that.

Just install Python 3 instead. Python 2 died on 1/1/2020.
