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
回答2:
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'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.
回答6:
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
回答7:
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.
回答8:
In centos 7. i'd use sudo yum install postgresql96-devel.x86_64 to solved my problem.
回答9:
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.
回答10:
For me, the missing package was
libpqxx-devel.x86_64
回答11:
This worked for me on Ubuntu Server 14.10 64-bit:
sudo apt-get install libpqxx-dev
