Step 1  Install latest python updates using this command  sudo apt-get install python-dev  Step 2  Add first dependency libxml2 version 2 7 0 or later sudo apt-get install libxml2-dev  Step 3  Add second dependency libxslt version 1 1 23 or later sudo apt-get install libxslt1-dev   Step 4  Install pip package management tool first  and run this command  pip install lxml  If you have any doubt Click Here

From Ubuntu 18 4  Bionic Beaver  it is advisable to use apt instead of apt-get since it has much better structural form   sudo apt install libxml2-dev libxslt1-dev python-dev   If you re happy with a possibly older version of lxml altogether though  you could try  sudo apt install python-lxml

As  Pepijn commented on  Druska  s answer  on ubuntu 13 04 x64  there is no need to use lib32z1-dev  zlib1g-dev is enough   sudo apt-get install libxml2-dev libxslt-dev python-dev zlib1g-dev

I also had to install lib32z1-dev before lxml would compile  Ubuntu 13 04 x64    sudo apt-get install lib32z1-dev   Or all the required packages together   sudo apt-get install libxml2-dev libxslt-dev python-dev lib32z1-dev

I installed lxml with pip in Vagrant  using Ubuntu 14 04 and had the same problem  Even though all requirements where installed  i got the same error again and again  Turned out  my VM had to little memory by default  With 1024 MB everything works fine    Add this to your VagrantFile and lxml should properly compile   install   config vm provider  virtualbox  do  vb    vb memory   1024 end   Thanks to sixhobbit for the hint  see  can  39 t installing lxml on Ubuntu 12 04

For Ubuntu 12 04 3 LTS  Precise Pangolin  I had to do   apt-get install libxml2-dev libxslt1-dev    Note the  1  in libxslt1-dev   Then I just installed lxml with pip easy install

For Ubuntu 14 04  sudo apt-get install python-lxml  worked for me

First install Ubuntu s python-lxml package and its dependencies   sudo apt-get install python-lxml   Then use pip to upgrade to the latest version of lxml for Python   pip install lxml

User · Answer

Since you re on Ubuntu  don t bother with those source packages  Just install those development packages using apt-get   apt-get install libxml2-dev libxslt1-dev python-dev   If you re happy with a possibly older version of lxml altogether though  you could try  apt-get install python-lxml   and be done with it
