After installing xcode I executed pip install Pillow and the last code strings say:

The actual problem is that Xcode's Command Line Tools is missing. To fix it, just run
xcode-select --install
on your terminal. A dialog will pop up, accept and Xcode's CLT will be installed.
See it here.
Did you uninstall PIL first?
Try:
pip uninstall pil
pip uninstall pillow
brew install libtiff libjpeg webp little-cms2
pip install pillow
See https://pillow.readthedocs.io/en/stable/installation.html for more information.
PIL is deprecated, use Pillow instead.
To install Pillow:
pip install Pillow
Install XQuartz.
X (or X11) is a (the default) *nix window system, which some *nix software that can be compiled on a Mac relies upon.
The problem appears to be that PIL and Pillow appear to assume you want Tk(inter), which in turns relies on X. If you don't want fancy dialog stuff for your image processing, there should be a way to turn that off, though that may require a manual installation.
Alternatively, perhaps this answer may be of use; but that still requires X to be installed, and just fixes a bad link.
Installing SDK headers worked for me
sudo installer -pkg /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg -target /

To fix the problem, I downloaded swig for windows at the time of writing this answer it was 3.0.12
For the latest swig windows version follow this link
Copy swig.exe to the python installation folder (for ex C:/python27)
Open the swigwin-3.0.12/Lib folder and copy all *.swg files to the C:/python27/Lib or equivalent python path
Open swigwin-3.0.12/Lib/python and copy all the files to C:/python27/Lib
Open the swigwin-3.0.12/Lib folder and copy over the typemaps folder to C:/python27/Lib
(Also make sure you have Microsoft Visual C++ Compiler for Python installed)
These steps worked for me.
conda install swig
pip install pocketsphinx
I didn't want to do all that setup other people are suggesting so I tried this and it worked.
This probably only works if you are using Anaconada though.
Instead of copying Swig files to the Python folder, you can simply add Swig`s location to the environment variables:
Press Ctrl+S
Type env and press Enter
Double click on Path
Add the path-to-Swig to the last blank line
Click OK and restart your PC
You try to install pocketsphinx with pip, that will download and compile this module. It requires some compiling tool like swig.
Another solution is to install a binary version of pocketsphinx. You can download a binary version here. You have to select the correct version with respect to your installation.
To determine which one you have to download, you can run the following commands, that will tell you which version you require and whether you run a 32 or 64 bit python interpreter.
"C:\Users\krush\Anaconda3\python.exe" --version
"C:\Users\krush\Anaconda3\python.exe" -c "import struct;print(struct.calcsize('P') * 8)"
Below are some commands that you may enter once you have downloaded the correct version
"C:\Users\krush\Anaconda3\python.exe" -m pip install pocketsphinx‑0.1.3‑cp35‑cp35m‑win32.whl
"C:\Users\krush\Anaconda3\python.exe" -m pip install pocketsphinx‑0.1.3‑cp36‑cp36m‑win_amd64.whl
I was also getting same error, while installing in ubuntu 16.04, I executed following commands:
sudo apt-get install -y python python-dev python-pip build-essential swig git libpulse-dev
sudo pip install pocketsphinx
source: pocketsphinx-python
In case you are working on anaconda navigator.
Just go to environment.
Search swig, your package will be displayed. Select the package and click on apply button.
It will also give a prompt list of other dependencies, which need to be installed with swig.
So just select all and click on apply button.
All the dependencies will be installed in your root directory of anaconda.
This worked for me, hope it helps.
There are few set of commands to resolve this. Just execute them:
sudo apt-get install -y python3 python3-dev python3-pip build-essential swig git libpulse-dev
sudo apt-get install libasound2-dev
sudo pip install pocketsphinx
what works for me is installing swing from conda and
conda install swig
if installed search where it is installed
where swig
then add that path to your environment variable
For mac users getting similar issues, there seems to be a problem with the current pip install framework. I followed this thread and used the solution linked. It doesn't seem like there will be a pip fix anytime soon.
Note you'll have to brew install swig before running the above steps - homebrew install link.
pip install pipwin
python -m pipwin install pocketsphinx
You can also use pipwin to install pocketsphinx.
For a purely pip-based fix (may or not work depending on your exact issue/system):
pip install swig
pip install pocketsphinx
pip freeze > requirements.txt
Fixed the issue simply for me. With pip freeze, you're likely to not have the issue again if cloning the project in another system (since swig will be installed just with pip install -r requirements.txt)
This is the kind of things for which it becomes REALLY worthwhile to look into using virtualenv or similar, instead of polluting (and endlessly re-configuring) your system.
I know I am late, but what worked for me was to download the pre-built wheel file and install it manually (tested on Windows. I am pretty sure it will only work on Windows).
https://www.lfd.uci.edu/~gohlke/pythonlibs/#pocketsphinx
Just grab the right one (cp39 = python 3.9). When it finishes downloading, navigate to your downloads folder in cmd, and issue the following command:
pip install pocketsphinx-0.1.15-cp39-cp39-win_amd64.whl
NOTE: Change pocketsphinx-0.1.15-cp39-cp39-win_amd64.whl to the name of the whl file you downloaded. I grabbed this one because I use Python 3.9 64bit version.
In Windows 10, I installed the linux subsystem.
In cmd, I run bash.
In bash,
I found that my current Python is 2.7.6.

You can install them using the following command.
Windows Subsystem for Linux / Debian / Ubuntu
sudo apt-get install python-dev
Fedora / RedHat / CentOS
sudo yum install python-devel
You need to install the python-dev package, which includes Python.h.
There is a much simpler solution, though - install Python for Windows, without using the Linux Subsystem. Starting with Python 3.5 pip sometimes (actually, quite often) installs the precompiled binary version, saving you a lot of trouble.
In fact, since Python 3.5, it's easier to install most packages on Windows than it is on Linux.
It's because of you didn't have python-dev or python3-dev packages due to your python version.
Just install them through 'pip' or 'pip3' package installer and enjoy it!
Note if you find the mentioned packages is installed and your problem is still exist!, you must look for 'Python.h' file in your file system by:
sudo find / -name "Python.h"
and then add listed paths which includes Python.h into your C_INCLUDE_PATH environment variable something like:
export C_INCLUDE_PATH=/usr/include/python3.6m/
and now retry your installation and enjoy!

Does anybody have an idea how to fix this?
It seems your numpy was installed using the distro package manager (i.e. by running apt-get install python3-numpy) since the numpy package is in the dist-packages directory of your python libs. Why don't you install scipy this way too? You can just run
sudo apt-get install python3-scipy
If you want to use pip, I suggest installing packages in virtualenv instances (or, even better, virtualenvwrapper) so that you avoid such conflicts. Otherwise, you should be using a systemwide version of pip, rather than a user installed one (the output says your pip belongs to user ubuntu), so you could first install it using apt-get and then make sure to use this new pip to install scipy.
Installing setuptools made it work for me on ubuntu 14.04
Python library gevent, version 0.13.6 (the current version on PyPI) will not pip install on OS X Lion, Python 2.7 (and probably others.) It works fine on Snow Leopard.
How can I get this library installed?
Bonus points if it can be done using pip install, rather than a manual or custom process, because then it will play nicely with automated builds.
Here is my pip install output:

gevent/libevent.h:9:19: error: event.h: No such file or directory
This means that the library which provides the event.h header is not installed. The library is called libevent (website).
In general, compilation errors like these are a flaw in the build scripts. The build script should give an error message that libevent is not installed, and it is a bug that it did not do so.
To get libevent from MacPorts and then manually tell compiler with CFLAGS environment variable where to find event.h and libevent while running pip.
sudo port install libevent
CFLAGS="-I /opt/local/include -L /opt/local/lib" pip install gevent
You can also use homebrew for installing libevent : brew install libevent
(from David Wolever's comment)
CFLAGS='-std=c99' pip install gevent
See in: Can't install gevent OSX 10.11
on OS X 10.11, clang uses c11 as the default, so just turn it back to c99.
After a while, I realized that the paths for the CFLAGS variable mentioned above works when installing libevent from port, but not from brew. The following worked for me (on OSX Mavericks):
$ brew install libevent
$ export CFLAGS="-I /usr/local/Cellar/libevent/2.0.21/include -L /usr/local/Cellar/libevent/2.0.21/lib"
$ pip install gevent
This is the way I found the easiest:
install libevent using homebrew
$ brew install libevent
install gevent
$ pip install gevent
This was the only way I could get it to work.
Found this answer when looking for help installing on Snow Leopard, posting this in case someone else comes this way with the same problem.
I had libevent installed via macports.
export CFLAGS=-I/opt/local/include
export LDFLAGS=-L/opt/local/lib
sudo pip install gevent
I had libevent installed via brew and it failed too, what worked was similar to what Stephen done, but pointing to brew default install:
CFLAGS=-I/usr/local/include LDFLAGS=-L/usr/local/lib pip install gevent
In case you install all from sources and use csh the following works on mac os 10.9
download latest stable http://libevent.org/ libevent-2.0.21-stable
./configure
make
sudo make install
virtualenv env
source env/bin/activate.csh
setenv CFLAGS "-I /usr/local/include -L /usr/local/lib"
pip install gevent
I use virtualenv and virtualenv wrapper, and so I wanted this to be self contained. I got gevent working like so:
Assuming you have virtual env setup, then:
workon {my_virtual_env}
Then download libevent and install it against the virtualenv.

sudo pip install cython git+git://github.com/gevent/gevent.git#egg=gevent
I am using MacOs High Sierra (10.13.3)
First I did :
brew install libevent
I upgraded my pip version to pip-18.0.
then tried installing again with following :-
pip install gevent
it worked.
Python library gevent, version 0.13.6 (the current version on PyPI) will not pip install on OS X Lion, Python 2.7 (and probably others.) It works fine on Snow Leopard.
How can I get this library installed?
Bonus points if it can be done using pip install, rather than a manual or custom process, because then it will play nicely with automated builds.
Here is my pip install output:
pip install gevent

Don't post the entire thing! That's too much! 90% of the time, the first error is enough...
gevent/libevent.h:9:19: error: event.h: No such file or directory
This means that the library which provides the event.h header is not installed. The library is called libevent (website).
In general, compilation errors like these are a flaw in the build scripts. The build script should give an error message that libevent is not installed, and it is a bug that it did not do so.
To get libevent from MacPorts and then manually tell compiler with CFLAGS environment variable where to find event.h and libevent while running pip.
sudo port install libevent
CFLAGS="-I /opt/local/include -L /opt/local/lib" pip install gevent
You can also use homebrew for installing libevent : brew install libevent
(from David Wolever's comment)
CFLAGS='-std=c99' pip install gevent
See in: Can't install gevent OSX 10.11
on OS X 10.11, clang uses c11 as the default, so just turn it back to c99.
After a while, I realized that the paths for the CFLAGS variable mentioned above works when installing libevent from port, but not from brew. The following worked for me (on OSX Mavericks):
$ brew install libevent
$ export CFLAGS="-I /usr/local/Cellar/libevent/2.0.21/include -L /usr/local/Cellar/libevent/2.0.21/lib"
$ pip install gevent
This is the way I found the easiest:
install libevent using homebrew
$ brew install libevent
install gevent
$ pip install gevent
This was the only way I could get it to work.
Found this answer when looking for help installing on Snow Leopard, posting this in case someone else comes this way with the same problem.
I had libevent installed via macports.
export CFLAGS=-I/opt/local/include
export LDFLAGS=-L/opt/local/lib
sudo pip install gevent
I had libevent installed via brew and it failed too, what worked was similar to what Stephen done, but pointing to brew default install:
CFLAGS=-I/usr/local/include LDFLAGS=-L/usr/local/lib pip install gevent
In case you install all from sources and use csh the following works on mac os 10.9
download latest stable http://libevent.org/ libevent-2.0.21-stable
./configure
make
sudo make install
virtualenv env
source env/bin/activate.csh
setenv CFLAGS "-I /usr/local/include -L /usr/local/lib"
pip install gevent
I use virtualenv and virtualenv wrapper, and so I wanted this to be self contained. I got gevent working like so:
Assuming you have virtual env setup, then:
workon {my_virtual_env}
Then download libevent and install it against the virtualenv.
curl -L -O https://github.com/downloads/libevent/libevent/libevent-2.0.21-stable.tar.gz
tar -xzf libevent-2.0.21-stable.tar.gz
cd libevent-2.0.21-stable
./configure --prefix="$VIRTUAL_ENV"
make && make install
I'm assuming you've got gcc 5+ installed (I use brew)
Hope this helps.
