ImportError: No module named lxml - Even though LXML Is installed

问题

I'm getting this error "ImportError: No module named lxml" Even though LXML Is definitely installed. Specifically it's installed within the python Virtualenv for the project. and ultimately I'm working on the Python/Amazon Product API. I get the error after trying to run one of the example scripts for that project from the terminal (mac).

How can I fix this? or further track down the issue?

Google searching lead me to:

Reintsall LXML
Ensure Xcode license was agreed to: sudo xcodebuild -license
Updating LXML with: pip install --upgrade lxml Currently at ver 3.4.0
reinstalled LXML dependencies as outlined here - pip install libxml2-dev libxslt-dev python-dev

Edit: More detail The line of code throwing the error is from lxml import etree, objectify, this is in a folder far away from where LXML is installed in my virtual environment (although I am running the script from within my virtualenv in terminal). If the issues is simply a matter of the script not knowing where to find the LXML install, how would I fix that?

回答1:

It turns out that I found my answer here: import lxml fails on OSX after (seemingly) successful install

Apparently, LXML Install on a Mac ends up installing it in the wrong path, so you have to reset the path using: export PATH="/Library/Frameworks/Python.framework/Versions/2.7/bin:${PATH}"

So it turns out that if you're using python via homebrew, things get a little sketchy with apps like Inkscape that have it hardcoded in their mind that a certain version of python is needed.

Getting the right python version was simply uninstalling brew & installing PIP:

brew uninstall --ignore-dependencies python

sudo easy_install pip

STATIC_DEPS=true sudo pip install lxml
