Homebrew install libxml2 with python modules

Question

Good morning,

I'm trying to install libxml2 with python modules. I have tried the following:

brew install --with-python libxml2                                                                  
==> Downloading ftp://xmlsoft.org/libxml2/libxml2-2.8.0.tar.gz
Already downloaded: /Users/brandon/Library/Caches/Homebrew/libxml2-2.8.0.tar.gz
==> ./configure --prefix=/usr/local/Cellar/libxml2/2.8.0 --without-python

As you can see... even with the --with-python flag, it is still configuring the source without python!

At the end of the install, homebrew says:

Generally there are no consequences of this for you.
If you build your own software and it requires this formula, you'll need
to add its lib & include paths to your build variables:

    LDFLAGS  -L/usr/local/Cellar/libxml2/2.8.0/lib
    CPPFLAGS -I/usr/local/Cellar/libxml2/2.8.0/include

When I try to install the gnome-doc-utils package:

Gnome-doc-utils requires libxml2 to be compiled
with the python modules enabled, to do so:
  $ brew install libxml2 --with-python

So obviously I tried again...

╰─ brew install libxml2 --with-python
Error: libxml2-2.8.0 already installed

I'm still new to this... so any help would be greatly appreciated.

Do you have any reason to not use [pip](http://pypi.python.org/pypi/pip/) (or [easy_install](http://packages.python.org/distribute/easy_install.html) as a last resort)? They use to behave much better than other packaging tools - and work with [virtualenv](http://pypi.python.org/pypi/virtualenv/)! — brandizzi, Jul 06 '12 at 22:30

First, you cannot install libxml2 because you already successfully installed it, so you will first need to uninstall it.

brew uninstall libxml2

Next you will need to edit the brew formula - which is simple enough to do --

type brew edit libxml2 and change the line

system "./configure", "--prefix=#{prefix}", "--without-python"

to this:

system "./configure", "--prefix=#{prefix}", "--with-python"

This does not fix the problem with the brew formula, but it does force the flag "--with-python", so the next time you type brew install libxml2 it will install the python libraries.

If you need to reset the formula (undo your changes), simply type brew update

I tried this but `make install` failed with `*** [install-am] Error 2` and `*** [install-recursive] Error 1`. – Hugh Guiney Sep 19 '13 at 21:33
Use `brew install --build-from-source libxml2` after editing libxml2 if it uses the bottled version. – revau.lt Sep 12 '21 at 21:09

This worked for me. First unlink/uninstall if done previously:

brew unlink libxml2
brew unlink libxslt
brew uninstall libxml2
brew uninstall libxslt

Then

brew install --framework python
brew install --with-python libxml2
brew install --with-python libxslt
brew link libxml2 --force
brew link libxslt --force

Voila!

This helped me with fixing some issues I was having with using the lxml parser in Beautifulsoup with a brew installed version of Python so thank you! – Kyle S. Feb 14 '16 at 19:35
point of order: brew will complain if you try and uninstall libxml2 *before* libxslt, because the former is required by the latter. Switching the order of the uninstalls worked for me – Christopher Hunter Apr 05 '17 at 19:25

The answer from kylehunt let me fix an issue that some how started to show up after I ran "brew upgrade" after upgrading to macOS Catalina:

If you happen to see things like

Error: libxml2: /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core/Formula/libxml2.rb:53: syntax error, unexpected <<
<<<<<<< Updated upstream
^~
/usr/local/Homebrew/Library/Taps/homebrew/homebrew-core/Formula/libxml2.rb:54: syntax error, unexpected ',', expecting end
...              "--with-history",
...                              ^
/usr/local/Homebrew/Library/Taps/homebrew/homebrew-core/Formula/libxml2.rb:55: syntax error, unexpected ',', expecting end
...            "--without-python",
...                              ^
/usr/local/Homebrew/Library/Taps/homebrew/homebrew-core/Formula/libxml2.rb:57: syntax error, unexpected ',', expecting end
...               "--with-python",
...

It means you should run

brew edit libxml2

To fix the config file as it might have been broken by merge conflicts during upgrade. Look for <<<<< in the file.

Homebrew install libxml2 with python modules
