Installing easy_install… to get to installing lxml

Question

I\'ve come to grips with the fact that ElementTree isn\'t going to do what I want it to do. I\'ve checked out the documentation for lxml, and it appears that it will serve my pu

Answer 1

Make sure that all the following packages are installed on your system first:

gcc gcc-c++ python-devel libxml2 libxml2-dev libxslt libxslt-dev

You should be able to install them using some variant of: sudo apt-get install sudo yum install

Only after all of the above have been successfully installed should you attempt to run:

sudo pip install lxml

Answer 2

First off we don't use easy_install anymore. We use pip. Please use pip instead.

To get to your particular troubles, as the comments point out, you're missing GCC. On OS X, Xcode Command Line Tools provides GCC, as well as many other programs necessary for building software on OS X. For OS X 10.9 (Mavericks) and newer, either install Xcode through the App Store, or alternatively, install only the Xcode Command Line Tools with

xcode-select --install

For more details, please see the Apple Developer FAQ or search the web for "install Xcode Command Line Tools".

For older versions of OS X, you can get Xcode Command Line Tools from the downloads page of the Apple Developer website (free registration required).

Once you have GCC installed, you may still encounter errors during compilation if the C/C++ library dependencies are not installed on your system. On OS X, the Homebrew project is the easiest way to install and manage such dependencies. Follow the instructions on the Homebrew website to install Homebrew on your system, then issue

brew update
brew install libxml2 libxslt

Possibly causing further trouble in your case, you placed the downloaded setuptools in /Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/. Please do not download any files to this location. Instead, I suggest you download the file to your home directory, or your usual Downloads directory. After downloading it, you're supposed to run sh setuptools-X.Y.Z.egg, which will then install it properly into the appropriate site-packages and put the executable easy_install on your path.

Answer 3

It looks like lxml wants to build an extension that requires access to a C compiler. You will need gcc for that. Try running sudo apt-get install build-essential and that should fix this particular issue.

Answer 4

Ensure you have libxml2-dev and libxslt1-dev installed

apt-get install libxml2-dev
apt-get install libxslt1-dev

Then your installation should build properly.

Answer 5

try: sudo apt-get install python-lxml
