Failed 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 during the cleanup phase:

 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 derived from pip.log:

Answer 1

Just install these things:

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

Then try again:

 pip install lxml 

Answer 2

Here is a similar question.

Error installing Pillow (and PIL)

Do you use MacOS? Perhaps you can try updating the command line tools and try "brew". If not, you can try installing pip and easy_intall tools again and updating it.

Answer 3

lxml has C depenedencies, often I run into problems when I miss libxslt or libxml2 . Are you sure that all dependencies on non-python are installed?
