Cannot Install Lxml on MAC Os X 10.9

Cannot install Lxml on Mac OS X 10.9

You should install or upgrade the commandline tool for Xcode.
Try this in a terminal:

xcode-select --install

Installing lxml OSX Mavericks 10.9.2

So the problem had nothing to do with the C compiler, it was in the python version used on the machine, apparently there was a conflict in python versions, a new clean installation of python solved the problem, and the .bash_profile. then we used the original command

pip install lxml

and it was successfully installed

How do I install lxml on Mac OS X 10.7.4? I have exhausted all options

I first installed MacPorts and then:

$ sudo port install python27 py27-lxml

And this gave me a functioning lxml installation.

Regarding your error messages, you appear to be missing the compiler command that pip is using to build lxml (llvm-gcc-4.2). Do you have the OS X development tools installed? You should find that file in /usr/bin/llvm-gcc-4.2; if it's not there, you probably need to download and install the development package.

You can install the XCode developer tools via the App Store. If you read the comments in the app store, you'll note that in order to make the command line tools available you need to install them separately. In XCode, go to Preferences->Downloads and download the "Command line tools" package.

pip install lxml on MacOS X gives error: command 'cc' failed

It is difficult to install cc without installing Xcode in mac.

See this documentation : https://hackercodex.com/guide/mac-development-configuration/

Also it is very easy to install Xcode in mac. Just download from app store, create an account if you don't have one.

Python3, lxml and Symbol not found: _lzma_auto_decoder on Mac OS X 10.9

I have deleted all versions of python from

      /Library/Frameworks/Python.framework/Versions/

afterwards I have reinstalled python 3 using brew and recreated the symlinks using

     brew link --overwrite python3
