How to install Subversion with python bindings on Mac

I'm doing:
$ brew install subversion --with-python
Yet, homebrew reports:
Warning: subversion: this formula has no --with-python option so it will be ignored!
It goes on to install subversion, as that was only a warning, but I need the Python bindings too.
I tried --with-python in other positions, but it does not make any difference.
Here's all the output:
Warning: subversion: this formula has no --with-python option so it will be ignored!

svntools have been installed to:
/usr/local/opt/subversion/libexec
The perl bindings are located in various subdirectories of:
/usr/local/opt/subversion/lib/perl5
If you wish to use the Ruby bindings you may need to add:
/usr/local/lib/ruby
to your RUBYLIB.
Bash completion has been installed to:
/usr/local/etc/bash_completion.d

Other info: I'm on macOS 10.13.6. Homebrew was upgraded today (no upgrades pending). There's a info page https://formulae.brew.sh/formula/subversion that suggests that --with-python is a real option, but that's not something the install command agrees with. At least on my computer. Swig is install on my mac (v3.0.12) via brew.

https://formulae.brew.sh/formula/subversion is out of date. The --with-python argument is not supported because the formula does the Python steps by default now.

Error installing Python 2 via Homebrew on MacOS Mojave

I'm having a lot of trouble with installing Python 2.7 on the MacOS 10.14 Mojave Beta.
Yes, I know that Python 2 comes pre-installed on the Mac, but I need a framework build of Python for my task.
I've tried re-installing the command line tools and then installing Python 2.7 as suggested here and here, but am still having issues - below is my output:

EDIT Please don't suggest Anaconda! For what I'm working on, I specifically need a framework built version of Python via Brew.
EDIT 2 - I tried reinstalling Sphinx, which happened with no problems. Upon doing that, I tried running install python#2 again, but had the same issue as before.
Below is the output of running brew doctor

I had the same problem.
I was able to fix it by completely uninstalling and reinstalling Python after following step by step in this answer: How to fix broken python 2.7.11 after OSx updates
After the reinstallation the problem was gone

As I read you output - this is not a problem with python directly it is a problem with sphinx which builds the docs. I would go for the following steps:
brew update && brew upgrade
brew install sphinx (maybe this gives a better error message or solves the problem if sphinx is installed before)
brew reinstall python#2
If this is not working: Did you reinstalled the commandline tools after upgrading to mac os 10.14? (xcode-select --install). If not installed/updated before do it and retry.
If this all is not working could you please execute brew doctor and post the output so we can better see whats going on with your homebrew instane?
Maybe it could be a option to make an roll back to a stable version of Mac OS (10.13) ?

I'd suggest you used the Anaconda Distribution of python. Anaconda offers both python 2.7 and python 3.6 with easy to use python installers for both versions. The Anaconda page explains how to install and run python on your mac.

os 10.11.6 pip install permission error

I am a CS beginner taking udemy python course and trying to install pip in order to use matplotlib, pandas and so on in pylab.
I use IDLE 3.4.2 and latest version Pycharm
Tried
1. "pip installed pylab"(version not satisfies the requirement pylab,no matching distribution found for pylab);
2.same result with sudo before the first one;
3.sudo easy_install matplotlib（succeeded in terminal, but still no matplotlib module in shell) ;
4.brew install python 3(succeeded , but still no matplotlib module in shell, and every command looks like still for 2.7)
5.Anaconda Package based on preinstalling Macports (same result as 3)
6.On cloud9.io, still can't import matplotlib
Then tried to uninstall both 2 and 3 python then install
7.brew rm -rf/Library/Frameworks/Python.framework/Versions/2.7

Errors installing Matplotlib - clang

I've tried to install Matplot lib but I'm still struggling to get past errors.
I've installed numpy and psipy but have the following error when I use easy_install (there is a similar error with pip).
And yes, I've installed the command line tools in Xcode in a bid to solve the 'gcc-4.2 not found' problem.

error: Setup script exited with error: command 'clang' failed with exit status 1

I recently had this issue as well, but I was using pip. If you have homebrew installed you can solve it by running the following commands:
brew install freetype
brew install libpng
brew link freetype
pip install git+https://github.com/matplotlib/matplotlib.git#egg=matplotlib-dev

theres actually an easier way! First see if X11 libraries are installed (ls /usr/X11/include)
If they aren't you may need to install X11
If they are then a simple fix is this:
cd /usr/X11/include
sudo ln -s freetype2/freetype
Basically for some reason its looking for the freetype library at /usr/X11 and its actually in the subfolder in freetype2. Odd - but it does then compile this way.

I did the following and it worked for me
sudo apt install libfreetype6-dev
pip install matplotlib

You're missing freetype2, or at least the development version. It's looking for ft2build.h, which is a freetype2 header file.
You can either try installing freetype2 from source, or just a package manager like macports, fink or homebrew to install it (for package managers, make sure you pick the development version if that's available).
But if you are going the route of package managers, you could also install matplotlib that way. And there may be binaries for OS X that include freetype2, so that may be even easier than installing from source.
The reason easy_install and pip don't install freetype2 for you, is that it's not a Python package.
== Correction ==
freetype2 should be available, not just where easy_install or pip expect it. On my Mac, I can ft2build.h in /usr/X11/include. So, you'll need to set the CFLAGS variable to that directory (and probably LDFLAGS to /usr/X11/lib`) to get the installation working. Now, with easy_install and pip, I'm not 100% sure how to do that. Try e.g.
CFLAGS=-I/usr/X11/include LDFLAGS=-L/usr/X11/lib easy_install matplotlib
Or, just download the matplotlib source, adjust setup.py and build it yourself.

Your graphviz installation could not be found.
Either the graphviz package is missing on incomplete
(binary packages graphviz-dev or graphviz-devel missing?).
If you think your installation is correct you will need to manually
change the include_path and library_path variables in setup.py to
point to the correct locations of your graphviz installation.
The current setting of library_path and include_path is:
library_path=None
include_path=None
Traceback (most recent call last):

Here is the path to Graphviz:

What do I need to do to get this installed?

It seems like you are missing the "pkg-config" package. You can install it with Homebrew
brew install pkg-config

2.14.1 is a very old version of graphviz. You may have better success using the official OS X installer package for 2.26 (at this writing) here. Then you will likely need to edit the pygraphiz setup.py to use the proper library_path and include_path. Most likely you will need to uncomment the /usr/local/lib/graphviz and usr/local/include/graphviz versions but use ls /usr/local to find out for sure.
On the other hand, with so many dependent libraries and packages involved, this is a perfect case for using a 3rd-party package manager like MacPorts which will manage all of the dependencies for you and allow you to easily update as new releases become available. Once you have installed the base MacPorts files, you can install it all with:
$ sudo port selfupdate
# either
$ sudo port install py26-pygraphviz # with MacPorts python2.6
# ... or
$ sudo port install py27-pygraphviz # with MacPorts python2.7

As Ned said,
Locate your setup.py file for graphviz. In my case, it was located at /Users/*my_username*/build/pygraphviz/setup.py
Finally, uncomment the lines corresponding to the Mac OSX paths for library_path and include_path. These are the lines containing: /usr/local/lib/graphviz and usr/local/include/graphviz
