Sharp: [Question] node-gyp error: ImportError: No module named parser

[biri]

I am trying to install Sharp and I keep getting node-gyp error. I tried to find solutions online but nothing works. I started a clean instance on EC2 to check and installed the same node and npm that I have on my computer and it worked there. Can you please let me know what's the problem

I am running ubuntu 16.04

npm install sharp
npm WARN prefer global [email protected] should be installed with -g

[email protected] install /home/test/Documents/proj/node_modules/sharp
node-gyp rebuild

Hello, ImportError: No module named parser is the salient part of the error message, and suggests modules from multiple versions of Python (2 and 3?) are conflicting with each other.

Thanks @lovell. I do have python 2.7.3 installed and in usr/local/lib I also see Python 3.5. When I run python --version I get 2.7.3

I saw that node-gyp doesn't support python 3 but I am not really using python for my development at the moment so no virtual environments or anything like that.

I also noticed that on the EC2 I started from scratch and I did succeed in installing Sharp I have python 2.7.6 installed and a python 3.4 directory in /usr/local/lib.
Any suggestions on how to solve it ?

i also tried to run

"npm install --python=python2.7 sharp" and I get the same error
"npm config set python python2.7"

If the parser module really is is missing, perhaps pip install parser might help.

(This is a problem relating to the Python setup on one specific machine so I'm probably not going to be much help.)

Thanks @lovell I fixed it. Apparently I had another python installed from a while ago and when I upgraded to 16.04 they collided. I removed the old one, and now I am only using the one the OS installed. Works great! Thanks
