Installing librosa

[FanonX Rogers]

Hello, 

I am having trouble installing librosa on my MacBook. I have tried 'sudo pip install librosa' as well as 'sudo pip install librosa --ignore six' and none of these have work. I feel like the problem does not have to do with librosa itself but with the system having permission to run librosa. 

The error states 

Found existing installation: numpy 1.8.0rc1

    DEPRECATION: Uninstalling a distutils installed project (numpy) has been deprecated and will be removed in a future version. This is due to the fact that uninstalling a distutils project will only partially uninstall the project.

That's indeed a strange one, and not something I've come across.

Maybe someone out there who uses OSX regularly can chime in?

My two cents: if at all possible, I recommend not using OSX's system python, and instead use (ana)conda environments: https://anaconda.org/

The "six" package should not be causing you any trouble here though.  It looks like the issue stems from having an old numpy version that needs to be upgraded, and somewhere along the way, you don't have permission to do so.  You could try "pip install --no-deps librosa", but there will be no guarantees that the dependencies are satisfied.

As an OS X user, I can say that I've definitely had problems with ownership when installing: Python mostly wants to be installed owned only by the user, but the system python is owned by root, so needs "sudo pip".  But then some other packages may have been installed with user permissions.  I don't remember the details, but I remember it being a mess.

I now run with the Anaconda python instead, as Brian recommends:

dpwe@dpwe-macbookpro2:~/Downloads$ which python

/Applications/anaconda/bin/python

Likewise, I also needed to use "sudo" to successfully install on OS X. I was able to install only using easy_install, not pip:

sudo easy_install numpy

sudo easy_install librosa
