Error: command 'gcc' failed with exit status when installing psycopg2

Question

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:

[root@server01 ~]# easy_install psycopg2

Answer 1

您需要为 PostgreSQL 安装开发包，例如在 Ubuntu 下是sudo apt-get install libpq-dev ... 而对于 CentOS 是yum install postgresql-devel

Answer 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

Answer 3

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

Answer 4

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,

Answer 5

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

Answer 6

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.

Answer 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.

Answer 8

在centos 7. 我会使用sudo yum install postgresql96-devel.x86_64来解决我的问题。

Answer 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.

Answer 10

这在 Ubuntu Server 14.10 64 位上对我有用：

sudo apt-get install libpqxx-dev

Answer 11

对我来说，丢失的包裹是

libpqxx-devel.x86_64

Answer 12

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.
