got error when installing spacy

I got error when installing spacy with pip (under mac python3). Following is the last part of the error report. It seams that there are much error. How can i fix it? I have installed gcc.

I'm really not sure if this is related or not but I saw a discussion this morning that said that the latest macOS upgrade (Catalina) drops support for 32-bit applications altogether. The reason I mention it is because the x86_64 conflicts with i386 could be referencing the 32-bit/64-bit problem.
Have you recently upgraded your Mac OS? And if so, maybe you need to upgrade your dependencies to 64-bit equivalents?

How to install PyGreSQL using Virtualenv on Mac OS Sierra

I'm configuring a virtualenv to work with a legacy webservices application developed on python using flask microframework and PostgreSQLdatabase, this application use PyGreSQL 5.0.3 as a dependency to connect with the database.
I have installed the PostgreSQL 9.6.1, i installed it using:
brew install postgresql
I have installed and working with Python 2.7
When i run the
pip install -r requirements.txt
i'm gettin this error message:

As you can see, this error is derived from compile and build the package, but I have the postgresql library installed, which I see as the common problem in other cases. On the other hand I have installed the command line tools of mac, i changed my compiler from cc to gcc and i'm having the same error
Any idea how to solve it, thank you in advance

I wasn't able to install any version of this package normally. It's probably a problem with the package.
Workaround: If you turn off warn-as-error, it should compile fine.
export CFLAGS="-Wno-error"
pip install PyGreSQL

install pyaudio with macOs Sierra

I upgraded my Mac to macOS Sierra and I had to start a new account. Right now I am trying to establish my environment. I ran into a problem installing pyaudio. The procedure I used is first use homebrew and install port audio.
brew install portaudio
It installs with no errors.
I proceed to install pyaudio using pip
pip install pyaudio
I receive the following error message.

^
1 error generated.
error: command 'cc' failed with exit status 1
portaudio.h is available in /usr/local/Cellar/portaudio/19.20140130/include
I am unfamiliar with pip and don't know how to pass the path to the complier.
Any help will be greatly appreciated.
thanks
Rod

Thanks for the suggestion. I tried it but it did not work.
It seems pip is not finding both include files and libraries when attempting to install in macOS Sierra
I did some digging into how to pass paths with pip and I successfully installed pyaudio using the following command.
sudo python3 -B -u -m pip -v install --no-warn-script-location --no-cache-dir --global-option=build_ext --global-option="-I$(brew --prefix portaudio)/include" --global-option="-L$(brew --prefix portaudio)/lib" pyaudio

Please try the command below.
sudo CPATH="$CPATH:/usr/local/include" LIBRARY_PATH="$LIBRARY_PATH:/usr/local/lib" pip install pyaudio

You can add the directory to your CPATH. Try:
CPATH="$CPATH:/usr/local/Cellar/portaudio/19.20140130/include"
pip install pyaudio

Error when trying to install pyamg: clang: error: no such file or directory: '“-I/.../boost_1_59_0”'

I am trying to install pyamg in my virtual environment. However, I am getting the following error. I am using mac OS.

Use Anaconda or Miniconda
conda install pyamg
takes only a few seconds.
You can create an environment with:
conda create --name my_env python=2.7
Change into it:
source activate my_env
and install pyamg:
conda install pyamg
You can still use pip to install packages conda cannot find.
Life is too short to spent time on compilation issues. ;)

I'm pretty sure that the -I at the beginning of the paths is what's screwing everything up. I bet if you tried adding those export statements back to .bashrc but took out the -I and -L prefixes then your original command would start working.
Perhaps you had those there for a reason, I've never seen that, but removing those prefixes would probably work.

Actually, I think #oarfish called it correctly in the comments. The problem seems to be the funny “ and ” characters in those paths, which are distinct from the usual " double quote symbol.
The following reproduces the error for me:

Any idea what might be going on here?

This is a known issue with OSX and recent Xcode upgrade.
Instructions how to avoid the issue are here:
Ansible Installation -clang: error: unknown argument: '-mno-fused-madd'
This should do the trick::
ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future pip install Pillow
