I need to install psycopg2 for openerp installation process, but I always faced that error. I've already used pip and easy_install and my gcc is the latest version. I really need your help to solve my problem.
This is my complete error with easy_install:

You'll need to install the development package for PostgreSQL, which for instance under Ubuntu is a sudo apt-get install libpq-dev... and for CentOS it's yum install postgresql-devel
For the case of CentOS, I had this very same problem, that I solved installing these packages:
sudo yum install postgresql-libs
sudo yum install postgresql-devel
sudo yum install python-devel
only then, I was able to perform successfully:
sudo easy_install psycopg2
May Your system is missing the Python headers. To fix this, run:
sudo apt-get install python-dev
or
sudo apt-get install python3-dev
On a fresh ubuntu 14.04.2 LTS on an EC2 instance, I was able to install psycopg2 after instaling the following packages:
sudo apt-get install gcc
sudo apt-get install postgres-xc-server-dev
sudo apt-get install libpq-dev
sudo apt-get install postgresql-client-common
sudo apt-get install postgresql-common
And on a fresh AMI linux (CentOS) instance:
sudo yum install postgresql-devel
sudo yum install gcc*
Hope it helps,

i had this problem but was solved by running:
pip install -Iv psycopg2==2.7.7
There is a problem installing the latest version + python3.7
I've been trying to install pgsql on a plain Amazon Linux EC2 instance, and have been getting this error. Per Nicolás answer, I installed his suggested list of packages, but I continued to get the error. Looking more closely at the error, I noticed that the gcc command was including pgsql93 files:
gcc -pthread -fno-strict-aliasing -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector --param=ssp-buffer-size=4 -m64 -mtune=generic -D_GNU_SOURCE -fPIC -fwrapv -DNDEBUG -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector --param=ssp-buffer-size=4 -m64 -mtune=generic -D_GNU_SOURCE -fPIC -fwrapv -fPIC -DPSYCOPG_DEFAULT_PYDATETIME=1 -DPSYCOPG_VERSION="2.6.1 (dt dec pq3 ext lo64)" -DPG_VERSION_HEX=0x09030A -DHAVE_LO64=1 -I/usr/include/python2.7 -I. -I/usr/include/pgsql93 -I/usr/include/pgsql93/server -c psycopg/psycopgmodule.c -o build/temp.linux-x86_64-2.7/psycopg/psycopgmodule.o -Wdeclaration-after-statement
Looking in /usr/include/ I see pgsql92/ but not pgsql93/. So I took a look at what pgsql-related yum packages were installed and I noticed these:
postgresql92.x86_64
postgresql92-devel.x86_64
postgresql92-libs.x86_64
postgresql93.x86_64
postgresql93-libs.x86_64
Seemed to me like there ought to be a postgresql93-devel, so I tried:
sudo yum install postgresql93-devel
And that fixed the problem for me! So I guess the theme is: Look at the gcc call, and see what dir it's pulling in. Follow the crumbs from there.
For Ubuntu 14.04, from Docker image python:3.4.3-slim this combination worked for me:
sudo apt-get update
sudo apt-get install -y build-essential
sudo apt-get install -y python3.4-dev
sudo apt-get install -y libpq-dev
pip3 install psycopg2
Note build-essential package. It was crucial in my case.
In centos 7. i'd use sudo yum install postgresql96-devel.x86_64 to solved my problem.
The invocation of gcc failed, gcc couldn't compile the source. Probably the cause is
./psycopg/psycopg.h:31:22: error: libpq-fe.h: No such file or directory In file included from psycopg/psycopgmodule.c:29:
that the header libpq-fe.h is nowhere in the search path if you have it at all.
This worked for me on Ubuntu Server 14.10 64-bit:
sudo apt-get install libpqxx-dev
For me, the missing package was
libpqxx-devel.x86_64
psycopg2 is also available on PyPI in the form of wheel packages for the most common platform (Linux, OSX, Windows): this should make you able to install a binary version of the module, not requiring the above build or runtime prerequisites.
You can use this command : pip install psycopg2-binary
Note The psycopg2-binary package is meant for beginners to start playing with Python and PostgreSQL without the need to meet the build requirements.
If you are the maintainer of a publish package depending on psycopg2 you shouldn’t use ‘psycopg2-binary’ as a module dependency. For production use you are advised to use the source distribution.
I was running 3.9-alpine for CICD and had to install these packages to get it working;
apk add postgresql-dev
apk add gcc
apk add musl-dev
Then I was able to run a pip install psycopg2 as normal.

I'm just getting started with Docker, so I decided I'd try to create a simple flask API app.
The problem is, I keep getting various errors depending on what I try to do to fix them.
My requirements.txt:
Flask
MySQL-python
bleach
bcrypt
My Dockerfile:
FROM ubuntu:latest
MAINTAINER Caleb Hester "naclcaleb#gmail.com"
ENV LANG C.UTF-8
RUN apt-get update -y
RUN apt-get install -y python-pip python-dev build-essential
COPY . /app
WORKDIR /app
RUN pip install -r requirements.txt
ENTRYPOINT ["python2.7"]
CMD ["api.py"]
I get this error: EnvironmentError: mysql_config not found
I tried a few things, including adding a apt-get -y build-dep python-mysqldb, but when I do that, I get an error about needing to add some URIs to my sources.list, and something about locales and C.UTF-8.
I'm very confused here.
Does anyone know what the proper docker file would be?
UPDATE:
After adding libmysqlclient-dev to my apt-get install, the MySQLdb error goes away, but now I'm getting this error for cffi:

Update:
I fixed this by adding libffi-dev to my apt-get install
You might be missing the mysql deb package.
Try appending libmysqlclient-dev to the line
RUN apt-get install -y python-pip python-dev build-essential
so that you now have
RUN apt-get install -y python-pip python-dev build-essential libmysqlclient-dev

I am trying to install kivy on ubuntu 16.04 . When I execute " python setup.py build_ext --inplace -f " this instruction shows above error please help me...
It is likely that you cython version is incorrect.
For the current version of kivy (1.10.0), I've had success with cython==0.26. Install failed with 0.27.1 and 0.27.3 with the same error as yours.
So in your relevant anaconda environment, uninstall the current cython:
pip uninstall cython==0.2x.x
(give the correct version of your installed cython)
or
conda uninstall cython
Install cython==0.26:
pip install cython==0.26
(there doesn't seem to be a 0.26 version of cython in the linux64 anaconda channel)
Then: pip install kivy
IMHO much easier is to use apt-get or pip.
pip install Cython #pip or pip3
pip install Kivy
EDIT:
Of course install gcc
What's your cython version? you might want to update it to 0.24 or 0.25 to build kivy.
pip install -U cython==0.25
I am using Kivy on Ubuntu 16.04 LTS and used the following installation steps. Kivy examples is optional:
$ sudo add-apt-repository ppa:kivy-team/kivy
$ sudo apt-get update
$ sudo apt-get install python3-kivy
$ sudo apt-get install python-kivy-examples
$ sudo pip install --upgrade cython==0.26
For kivy version 1.10.0, cython must be 0.26
When i am trying to install Snappy on alpine linux using:
pip install snappy
I am getting the following error when it tries to install a required package called cypari.
I installed snappy from "apk add snappy"
gcc -fno-strict-aliasing -Os -fomit-frame-pointer -g -DNDEBUG -Os -fomit-frame-pointer -g -fPIC -Ilibcache/pari64/include -I/usr/include/python2.7 -c cypari_src/_pari.c -o build/temp.linux-x86_64-2.7/cypari_src/_pari.o
In file included from cypari_src/_pari.c:460:0:
cypari_src/implementation.c:47:22: fatal error: execinfo.h: No such file or directory
#include <execinfo.h>
I solved this problem by running apk add libexecinfo libexecinfo-dev
Then using apk add snappy
Then using pip install python-snappy
if you use pip install snappy it installs a completely different library which is this
Combining previous answers, this minimal Dockerfile works for me
FROM python:3.6-alpine
RUN apk add --no-cache g++ snappy-dev && \
pip install --no-cache-dir --ignore-installed python-snappy
Installing execinfo-dev suffice, since execinfo.h is in that package.
You can check it here:
http://pkgs.alpinelinux.org/contents?file=execinfo.h&path=&name=&branch=&repo=&arch=
apk add snappy
will install the package, so you don't need to:
pip install snappy
To expand on the answer from #dwardu, I also had to install the snappy-dev package. That fixed this error I was getting from pip install:
snappy-c.h: No such file or directory
I am trying to set up a virtualenv for a Django project. It needs MySQL-python. I'm trying to replicate the production environment, which uses Python 2.5. My Ubuntu desktop has Python 2.5.

I have installed the python-dev Ubuntu deb package, but that's for Python 2.6.
How else can I get MySQL-python installed?
I had this same problem on an Ubuntu box. Prior to installing MySQL-python via pip, I needed to compile the module and dependencies from source using the following command:
sudo apt-get build-dep python-mysqldb
see this article - http://theviceprogrammer.com/?p=238
Actually, found a solution, I enabled the Dead Snakes - old python version repository, then I could aptitude install python2.5-dev, and then pip install MySQL-python worked
Instead of using pip or easy_install, you can use apt-get:
sudo apt-get install python-mysqldb
Requiring from source as per adam's reply wasn't require for me, on Ubuntu 12.04 w/ Python 2.5
