I am assuming you are here because like me, you installed a bazillion different python interpreters on mac and the whole thing is a spagetti.Today, I finally fixed my python installation. Whatever I install for python2 or python3 using pip JUST.WORKS.. My god! finally.

What the hell?

Here is what I had messed up, which you also probably did:

Nov 09, 2012  The Library folder at the root level of your hard drive is a public ‘library’ of data that is required for all users of the Mac. The Library folder within the System folder is critical for the operation of your Mac. Don’t ever remove, rename or otherwise move this directory in any way. Leave it alone!

  • I had too many different python interpreters
  • Too many different symlinks which I lost track of
  • almost no package I installed with pip worked without a headache
  • any attempt to fix using online resources made it worse.

Let's set things right

  • First, remove all the python packages you installed. I am not sure if this is really necessary, but I did it just so I get a fresh start

  • Also remove pip cache because why not:
  • Now remove pip
  1. Jul 26, 2018 Mac OS needs python. DO NOT remove any versions of Python found in the following folders: /usr/bin; system/Library; These versions of Python—which should be Python 2.7—are installed by Apple and used by Mac OS and other software to perform some functions.
  2. A protip by silvercorp about python, console, and mac.
  • Remove all the third party python installations:Careful! Don't delete anything under the /System/ folder. Otherwise you WILL have to reinstall macos, it WILL crash, don't do it.

(source: https://stackoverflow.com/a/3819829/2770195 but I changed it a bit to remove python3 too)

  • Remove python path stuff
    Edit whatever shell profile you have, like .bash_profile or .zshrc and .zprofile or whichever shell you are using (If you don't know what I'm talking about then it's .bash_profile):
    Delete all lines that have Python.framework in it. In other words, delete old paths related to python.

(source: https://stackoverflow.com/a/3819829/2770195 again)

  • If you have anaconda installed, get rid of that too:

(source: https://docs.anaconda.com/anaconda/install/uninstall/)

So far all this was standard. What's important is how you install the new version. Here's the fun part: if you already messed up your python environment,then there is a good chance you messed up permissions with some packages too. Thus any attempt to install new python versions will seem to work fine for now, but will be a brat later on. That's why the next step is so important:

  • Fix old package permissions:

Basically, everything in this folder is supposed to NOT require root priviliges, which if they do they give pip a hard time later on. That's why we made everything belong to us

Let's install the one and only python2 we will use!:

(don't worry we will get to python3 as well)
Now that you fixed the permissions, you can go ahead and install a python2 interpreter that will NOT ever require sudo with pip and hence will install your packages just fine:Here is the trick: We are NOT using easy_install. Got it? No easy_install. It's the devil. brew is love, use brew:

  • If you don't have brew installed (firstly you should be ashamed of yourself):

Go to your .profile file again

and add these lines:

now install python2 using brew:

(this will also install pip)
(source: https://docs.python-guide.org/starting/install/osx/)

Ok, if you haven't screwed up anything so far, you should be able to use pip with a peace of mind.I just tried a bunch of packages like numpy and plotly they all worked right away

Install python3 (optional)

(yes, this installs latests python, which is right now python3. Also installs pip)

gg wp. Now do me a favor and end aging before I die. Just saying. Have fun.

Python on a Macintosh running Mac OS X is in principle very similar to Python onany other Unix platform, but there are a number of additional features such asthe IDE and the Package Manager that are worth pointing out.

4.1. Getting and Installing MacPython¶

Mac OS X 10.8 comes with Python 2.7 pre-installed by Apple. If you wish, youare invited to install the most recent version of Python 3 from the Pythonwebsite (https://www.python.org). A current “universal binary” build of Python,which runs natively on the Mac’s new Intel and legacy PPC CPU’s, is availablethere.

What you get after installing is a number of things:

  • A Python3.8 folder in your Applications folder. In hereyou find IDLE, the development environment that is a standard part of officialPython distributions; PythonLauncher, which handles double-clicking Pythonscripts from the Finder; and the “Build Applet” tool, which allows you topackage Python scripts as standalone applications on your system.

  • A framework /Library/Frameworks/Python.framework, which includes thePython executable and libraries. The installer adds this location to your shellpath. To uninstall MacPython, you can simply remove these three things. Asymlink to the Python executable is placed in /usr/local/bin/.

The Apple-provided build of Python is installed in/System/Library/Frameworks/Python.framework and /usr/bin/python,respectively. You should never modify or delete these, as they areApple-controlled and are used by Apple- or third-party software. Remember thatif you choose to install a newer Python version from python.org, you will havetwo different but functional Python installations on your computer, so it willbe important that your paths and usages are consistent with what you want to do.

IDLE includes a help menu that allows you to access Python documentation. If youare completely new to Python you should start reading the tutorial introductionin that document.

If you are familiar with Python on other Unix platforms you should read thesection on running Python scripts from the Unix shell.

4.1.1. How to run a Python script¶

Your best way to get started with Python on Mac OS X is through the IDLEintegrated development environment, see section The IDE and use the Help menuwhen the IDE is running.

If you want to run Python scripts from the Terminal window command line or fromthe Finder you first need an editor to create your script. Mac OS X comes with anumber of standard Unix command line editors, vim andemacs among them. If you want a more Mac-like editor,BBEdit or TextWrangler from Bare Bones Software (seehttp://www.barebones.com/products/bbedit/index.html) are good choices, as isTextMate (see https://macromates.com/). Other editors includeGvim (http://macvim-dev.github.io/macvim/) and Aquamacs(http://aquamacs.org/).

To run your script from the Terminal window you must make sure that/usr/local/bin is in your shell search path.

To run your script from the Finder you have two options:

  • Drag it to PythonLauncher

  • Select PythonLauncher as the default application to open yourscript (or any .py script) through the finder Info window and double-click it.PythonLauncher has various preferences to control how your script islaunched. Option-dragging allows you to change these for one invocation, or useits Preferences menu to change things globally.

4.1.2. Running scripts with a GUI¶

With older versions of Python, there is one Mac OS X quirk that you need to beaware of: programs that talk to the Aqua window manager (in other words,anything that has a GUI) need to be run in a special way. Use pythonwinstead of python to start such scripts.

With Python 3.8, you can use either python or pythonw.

4.1.3. Configuration¶

Python on OS X honors all standard Unix environment variables such asPYTHONPATH, but setting these variables for programs started from theFinder is non-standard as the Finder does not read your .profile or.cshrc at startup. You need to create a file~/.MacOSX/environment.plist. See Apple’s Technical Document QA1067 fordetails.

For more information on installation Python packages in MacPython, see sectionInstalling Additional Python Packages.

4.2. The IDE¶

MacPython ships with the standard IDLE development environment. A goodintroduction to using IDLE can be found athttp://www.hashcollision.org/hkn/python/idle_intro/index.html.

4.3. Installing Additional Python Packages¶

There are several methods to install additional Python packages:

How To Remove Python In Library Mac

  • Packages can be installed via the standard Python distutils mode (pythonsetup.pyinstall).

  • Many packages can also be installed via the setuptools extensionor pip wrapper, see https://pip.pypa.io/.

4.4. GUI Programming on the Mac¶

There are several options for building GUI applications on the Mac with Python.

PyObjC is a Python binding to Apple’s Objective-C/Cocoa framework, which isthe foundation of most modern Mac development. Information on PyObjC isavailable from https://pypi.org/project/pyobjc/.

The standard Python GUI toolkit is tkinter, based on the cross-platformTk toolkit (https://www.tcl.tk). An Aqua-native version of Tk is bundled with OSX by Apple, and the latest version can be downloaded and installed fromhttps://www.activestate.com; it can also be built from source.

How To Remove Number From List Python

wxPython is another popular cross-platform GUI toolkit that runs natively onMac OS X. Packages and documentation are available from https://www.wxpython.org.

How To Remove Python In Library Mac Os

PyQt is another popular cross-platform GUI toolkit that runs natively on MacOS X. More information can be found athttps://riverbankcomputing.com/software/pyqt/intro.

4.5. Distributing Python Applications on the Mac¶

The “Build Applet” tool that is placed in the MacPython 3.6 folder is fine forpackaging small Python scripts on your own machine to run as a standard Macapplication. This tool, however, is not robust enough to distribute Pythonapplications to other users.

Python How To Remove Packages

The standard tool for deploying standalone Python applications on the Mac ispy2app. More information on installing and using py2app can be foundat http://undefined.org/python/#py2app.

4.6. Other Resources¶

The MacPython mailing list is an excellent support resource for Python users anddevelopers on the Mac:

Another useful resource is the MacPython wiki:
