libxml install error using pip

** make sure the development packages of libxml2 and libxslt are installed **

From the lxml documentation, assuming you are running a Debian-based distribution :

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

For Debian based systems, it should be enough to install the known build dependencies of python-lxml or python3-lxml, e.g.

sudo apt-get build-dep python3-lxml

This worked for me:

yum install libxslt-devel libxml2-devel

In case, you are using Ubuntu/Lubuntu 13.04 or Ubuntu 13.10 and having problem with "/usr/bin/ld: cannot find -lz", you may need also install zlib1g-dev package:

sudo apt-get install -y zlib1g-dev

Put it all together:

sudo apt-get install -y libxml2-dev libxslt1-dev zlib1g-dev python3-pip
sudo pip3 install lxml

No you are missing the Python header files. This mostly happens on Linux when you are using the system Python (there are reasons not to do that, but that's a different question).

You probably need to install some package, and it's probably called python-dev or python-devel.

 sudo yum install python-devel

or

 sudo aptitude install python-dev

Or somesuch.

I solved this issue by increasing my server ram.

I was running only 512 MB and when I upgraded to 1 GB I had no problem.

I also installed every package manually prior to this in an attempt to fix the problem, but I'm not sure whether this is a necessary step.

On Windows I had the same error on windows when trying to manually install in Python 3.4 after it had been installed on 3.3. I finally was able to solve it by installing the wheel and running pip from the Python34 directory.

1) download wheel from here: http://www.lfd.uci.edu/~gohlke/pythonlibs/#lxml

2) cd Python34\Scripts

3) pip.exe C:\Users\Home\Downloads\lxml- ......... .whl

just install requirements:

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

Now, you can install it with pip package management tool:

pip install lxml

error: command 'gcc' failed with exit status 1

yum remove audit
yum install gcc
yum install libxslt-devel libxml2-devel

cd lxml-x.x.x
python setup.py build
python setup.py install

I am using Ubuntu 14.04 and this solves the issue for me

sudo apt-get build-dep python3-lxml
sudo apt-get install libxml2-dev libxslt-dev python-dev
RdB
STATIC_DEPS=true easy_install lxml

Installing a lxml binary would do the trick. Check this

I was having this issue with a pip install of lxml. My CentOS instance was using python 2.6 which was throwing this error.

To get around this I did the following to run with Python 2.7:

  1. Run: sudo yum install python-devel
  2. Run sudo yum install libxslt-devel libxml2-devel
  3. Use Python 2.7 to run your command by using /usr/bin/python2.7 YOUR_PYTHON_COMMAND (For me it was /usr/bin/python2.7 -m pip install lxml)

sudo apt install libxslt-dev libxml2-dev

and then try upgrading python setuptools

pip install -U pip setuptools

this should resolve it.

pymemcompat.h:10: fatal error: Python.h: 没有那个文件或目录

Boy you should post your error log with LANG=C or people can't get the real cause from your log. The log above says: No such file or directory.

That means you should install the develop package of Python. That's usually "python-dev" on Debian flavored distro, and "python-devel" on RHEL flavored distro.

All the answers above assume the user has access to a privileged/root account to install the required libraries. To install it locally you will need to do the following steps. Only showed the overview since the steps can get a little involved depending on the dependencies that you might be missing

1.Download and Compile libxml2-2.9.1 & libxslt-1.1.28(versions might change)

2.Configure each install path for both libxml and libxslt to be some local directory using configure. Ex. ./configure --prefix=/home_dir/dependencies/libxslt_path

3.Run make then make install

4.Download and compile lxml from source

This works for me, 12.04, python2.7.6

sudo apt-get install libxml2 libxml2-dev libxslt1-dev
sudo pip install lxml

I know I am late to the show,

But this will help if nothing else works out

mkdir ~/tmp
export TMPDIR=~/tmp
STATIC_DEPS=true easy_install-2.7 lxml

Setting TMPDIR will ensure that the build can run everything that it needs to run, and setting STATIC_DEPS will tell it to pull in its own libxml2 and libxslt2, instead of using the old versions installed on the server.

Using cygwin 64 with Windows 8.

I have got...

pip install lxml (...)

I have tried everything until I realized a new cygwin toolchain has messed up python logic. cygwin install a compiler called "realgcc" that is not a real gcc.

Solution

Install gcc. Ex:

 apt-cyg install gcc-g++
Datalker

The only thing helped for me was 

sudo apt-get install python3.5-dev

I got the same error on my Linux machine.If you go to their website that's in their documentation as well.So if you get this kind of error in Linux machine, please try out these commands,

# apt install libxml2-dev libxslt-dev python-dev

# pip install lxml==3.4.4

I am using Ubuntu 12, and this works for me:

sudo apt-get install libxml2-dev
sudo apt-get install libxslt1-dev
sudo apt-get install python-dev
sudo apt-get install lxml
clilye

If you have installed the libxml2 and libxslt, maybe you need to create a symbolic link between libxml2 and libxslt path to python2.6 include path. Also you can try to add INCLUDE environment argument. Because the gcc command only search this path: -I/usr/include/python2.6.

The below file worked for me on windows https://pypi.python.org/pypi/lxml/3.3.3#downloads

On osx 10.10.5 and in a virtualenv, maybe you can resolve that problem like below:

sudo C_INCLUDE_PATH=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/usr/include/libxml2:/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/usr/include/libxml2/libxml:/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/usr/include pip install -r lxml

I work on a Windows machine. And here are some pointers for successful installation of lxml (with python 2.6 and later).

Have the following installed:

  1. MingGW.
  2. libxml2 version 2.7.0 or later.
  3. libxslt version 1.1.23 or later.

All are not available at a pip install.

libxml2's windows binary is found here.

libxslt is found here.

After you are done with the above two,

do : pip install lxml.

Another workaround is using the stable releases from PyPI or the unofficial Windows binaries by Christoph Gohlke (found here).

Using Windows 7 with Cygwin, I came across:

Compile failed: command 'gcc' failed with exit status 1
cc -I/usr/include/libxml2 -I/usr/include/libxml2 -c /tmp/xmlXPathInitZsgdMQ.c -o tmp/xmlXPathInitZsgdMQ.o
*********************************************************************************
Could not find function xmlCheckVersion in library libxml2. Is libxml2 installed?
*********************************************************************************
error: command 'gcc' failed with exit status 1

I fixed it by installing mingw64-x86_64-libxslt

For Windows:

pip install --upgrade pip wheel
pip install bzt
pip install lxml
