Homebrew install libxml2 with python modules

问题:

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...

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

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

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!

What worked for was installing libxml2 with --with-python in brew command

brew install --with-python libxml2
