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:

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https://formulae.brew.sh/formula/subversion is out of date.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.

I'm trying to get the hg-git extension to work with TortoiseHg (v5.8 on Win10). I have enabled the "hggit" extension in the settings. But when I try to push to github I get an error:
*** failed to import extension hggit: No module named hggit
Searching my drives I only have on hg executable in the TortoiseHg directory but can not find any hggit or hg-git binaries. Is there something else one have to do to get the extension working?
UPDATE - a beta release of THG 6.1.2 apparently has restored hggit and is available now:
https://foss.heptapod.net/mercurial/tortoisehg/thg/-/issues/5752#note_185806
I haven't tried it yet myself.
That post also notes:
The plan is for a py3 installer to be available with the next major
release [in July 2022]
Original answer:
Apparently at the moment THG has the option to include hggit in the settings, but does not actually package hggit itself.
According to Matt Harbison, one of the contributors/maintainers of TortoiseHG:
I took [hggit] out because it was always lagging behind changes in core hg,
and its dependencies broke stuff.
He goes on to add:
install by simply running py -2 -m pip install hg-git --user if you
have python2 installed on your system.
Another person (Aurélien Campéas) states the following for using Python 3:
with python 3 and a plain "pip install mercurial hg-git" and it just
works
Further, this other post by Keith Turkowski describes a full installation of THG and hggit with Python3 on Windows:
Install python-3.9.2-amd64.exe (if you want to use Python 3 and have Python.exe in the path)
Install putty-0.74-installer.msi (for SSH support)
Install tortoisehg-5.7.0-x64.msi
Install python-2.7.18.amd64.msi (For current user, Python.exe not in path)
Win+R -> cmd (command prompt): py -2 -m pip install hg-git --user
Enable hggit in TortoiseHg Settings (Extensions)
I assume you could use newer versions of the THG, Python, etc. installers.
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:

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.
I'm trying to setup a working environment on my mac:
brew install opencv3 --c++11 --with-contrib --with-gphoto2 --with-python3
==> Installing opencv3 from homebrew/homebrew-science

==> Caveats
This formula is keg-only, which means it was not symlinked into /usr/local.
opencv3 and opencv install many of the same files.
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 to your
build variables:
LDFLAGS: -L/usr/local/opt/opencv3/lib
CPPFLAGS: -I/usr/local/opt/opencv3/include

So homebrew seems to think the install went well, but
locate cv2.so finds nothing...
locate *cv*.so

and

cv2.py or cv.py does not exist as well...
Any ideas?
ive seen this error before using raspian, its also seen in ubuntu, renaming cv2.cpython-35m-darwin.so to cv2.so may help fix the issue.
ive heard it just a standard naming error.
I'm not having much success when attempting building pgmagick on OS X Lion with XCode 4.3.1.
I've installed both ImageMagick and GraphicsMagick, along side boost, using the following commands (via homebrew):
$ brew install graphicsmagick --with-magick-plus-plus
$ brew install imagemagick --with-magick-plus-plus
$ brew install boost --with-thread-unsafe
then I'm cloning the repo at https://bitbucket.org/hhatto/pgmagick:
$ hg clone https://bitbucket.org/hhatto/pgmagick/src
$ cd pgmagick
$ python setup.py build
However I always receive the following error:
ld: library not found for -lboost_python
collect2: ld returned 1 exit status
Based on the output on stdout, setup is looking in the right place for the boost (/usr/local/lib).
I've also tried easy_install and pip but with no luck. I'm using Pythonbrew but have also disabled this and tried using the stock python install -- still no success.
Any suggestions on how I can fix the problem, or further diagnose the issue?
According to my own reproduction of this issue in brew 0.9 and OSX 10.6.8, the problem is --with-thread-unsafe isn't being honored by the current brew formula file. You can verify this by checking the formula with brew edit boost and seeing if the option appears within the contents of the formula.
Because of this, libboost_python-mt.a and libboost_python-mt.dylib are being built instead of libboost_python.a and libboost_python.dylib.
The easiest ways to fix this are to edit your pgmagick setup.py to replace boost_lib="boost_python" with boost_lib="boost_python-mt" (as pointed out here) or to follow the instructions and patch here. It's otherwise a known issue.
The boost_python lib inside /usr/local/lib/ is named after libboost_python-mt.a and libboost_python-mt.dylib, since the default compiling is w/ multi-threads supporting enabled.
Grep boost_lib="boost_python" under ELSE condition in setup.py and replace it w/ boost_lib="boost_python-mt", will fix the "not found" issue.
Also it's OK to ln "-mt" version to libboost_python.a: as described here for linux boost which no longer appends '-mt' suffix since 1.42.
Ignore this line or you could "with-boost-python=boost_python-mt python setup.py install".
You could probably append '--with-boost-python=boost_python-mt' to extra_compile_args inside setup.py, to achieve the same goal.
Furthermore, you could install pgmagick through pip in managed envs. Refs http://rohanradio.com/blog/2011/12/02/installing-pgmagick-on-os-x/
Note that as of July 2014 the boost Python library is a separate homebrew package called boost-python.

Split out Boost.Python
You need to install it separately to get the libboost_python shared library.
Does setting DYLD_FALLBACK_LIBRARY_PATH=/usr/local/lib in the environment help before the build
e.g
$ export DYLD_FALLBACK_LIBRARY_PATH=/usr/local/lib
$ hg clone https://bitbucket.org/hhatto/pgmagick/src
$ cd pgmagick
$ python setup.py build
I've submitted a pull request to homebrew to build Boost with both mt and non mt (threaded and thread unsafe) binaries which are required to build pgmagick.
Turns out this is a rather common problem, until the patch is accepted, you can check out or use my formula for Boost to build pgmagick.

You could try the suggested workaround given by the brew script--rename /Library/Frameworks/Python.framework/Versions/Current/Python to something else to get it out of the linker's search path, repeat the brew install, then put it back.
If you don't need Python bindings in your PostgreSQL, you can also just install it without Python bindings using brew install postgresql --no-python.
This command is installing the server, not the python bindings. Is that what you want? There is a installer for osx that will install the server for you.
Once you have done that, you can install the psycopg2 bindings directly from source.
