I got same error. I want to know how to solve it too.
I show my environment below:
・macOS Mojave
・version 10.14.2 (18C54)
・MacBook(Retina, 12-inch , 2017)

I had the same problem in Mojave and solved it.
You can pass compile option by adding extra_compile_args as following in setup.py.
swig_opts=['-c++'],
extra_compile_args = ['-stdlib=libc++'],

[Ryo-Kawanami]

Thank you for sharing your solution.
But, I got new error below:

x86_64-3.6/pafprocess_wrap.o -o /Users/kawanami/workspace/tf-pose-estimation/tf_pose/pafprocess/_pafprocess.cpython-36m-darwin.so
clang: warning: libstdc++ is deprecated; move to libc++ with a minimum deployment target of OS X 10.9 [-Wdeprecated]
ld: library not found for -lstdc++
clang: error: linker command failed with exit code 1 (use -v to see invocation)
error: command 'g++' failed with exit status 1

My MacOS version is 10.14.2 and following url says "XCode 10.1 (with its command line tools) fixes it again, that's likely why running xcode-select --install works again. I think the problem was in 10.0 only."

I solved it.
Firstly, mojave user has to install "Command Line Tools (macOS 10.13) for Xcode 9.4.1" from this link [https://developer.apple.com/download/more/].
In this website, please search with "Command Line Tools".

And after install "Command Line Tools (macOS 10.13) for Xcode 9.4.1", please try below:

$ cd tf_pose/pafprocess

$ swig -python -c++ pafprocess.i && python3 setup.py build_ext --inplace

I hope you can solve this matter.

You can pass compile option by adding extra_compile_args as following in setup.py.
swig_opts=['-c++'],
extra_compile_args = ['-stdlib=libc++'],

To solve the second error too, it is enough to add a link option too in the same file:
extra_link_args=['-stdlib=libc++'],

Installing a previous version of Xcode is not the best option since you are simply using a deprecated library.

Thanks! My bug got solved by this!

I added these to setup.py but get the error clang: error: invalid deployment target for -stdlib=libc++ (requires OS X 10.7 or later). Any ideas how I can fix this?

I am running Mojave 10.14.6 and using swig installed via homebrew.

When compiling with libc++ the recommended minimum deployment target is 10.9 according to https://developer.apple.com/documentation/xcode_release_notes/xcode_10_release_notes

Add the following to setup.py to fix the invalid deployment target error:

os.environ['MACOSX_DEPLOYMENT_TARGET'] = '10.9'
