Fail to install lxml using pip

Question

This is the command I used to install lxml:

sudo pip install lxml

And I got the following message in the Cleaning Up stage:

Cleaning up...
Command /usr/bin/python -c "import setuptools,     tokenize;__file__='/private/tmp/pip_build_root/lxml/setup.py';exec(compile(getattr(tokenize, 'open', open)(__file__).read().replace('\r\n', '\n'), __file__, 'exec'))" install --record /tmp/pip-rUFjFN-record/install-record.txt --single-version-externally-managed --compile failed with error code 1 in /private/tmp/pip_build_root/lxml
Storing debug log for failure in /Users/georgejor/Library/Logs/pip.log

After that, I got:

ImportError: No module named lxml

Please help. Thanks!

The following output is from pip.log:

Answer 1

Just install these stuff :

sudo apt-get install libxml2-dev libxslt-dev  python-dev  python-setuptools

Then try again :

pip install lxml

Here is a similar question.

Error installing Pillow (and PIL)

Are you using a MacOS? Maybe you can try to update the commandline tools and try 'brew' tool. If not, you can try to install pip and easy_intall tools again, and update it.

Answer 3

lxml has C depenedencies, often I run into issues when I'm missing libxslt or libxml2. Are you sure that all non python dependencies are installed?
