Pip install fails on Mac OS 10.14

[clovetea]

On Mac OS 10.14, when running "pip3 install pycld2" with Python 3.6.2 or Anaconda Python 3.6.5, I get this error

The same thing happened to me. My python version is 3.5.2

Facing the same issue. Is there a way we can downgrade the xcode version to make this work? (assuming the case is xcode version)

The same issue with you guys. The more inforamtion please see below

  Failed building wheel for pycld2

I have the same problem here with macOX 10.14; same anaconda and python version

[jpab]

same error here, my solution was run:

CFLAGS=-stdlib=libc++ pip install pycld2

[bsolomon1124]

I think we may be able to include this in extra_compile_args param to setup, but a bit afraid if that would mess with other builds.

[swetha0613]

I tried installing through `CFLAGS=-stdlib=libc++ pip install pycld2 but I get :
invalid deployment target for -stdlib=libc++ (requires OS X 10.7 or later) error
