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                                 


        

Answer 1

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

Answer 2

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

brew install --with-python libxml2

Answer 3

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!

Answer 4

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.
