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

你需要安装PostgreSQL的开发包，例如在Ubuntu下面是一个sudo apt-get install libpq-dev ...而对于CentOS来说它是yum install postgresql-devel

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:

我一直在尝试在普通的Amazon Linux EC2实例上安装pgsql，并且一直在收到此错误。 PerNicolás回答，我安装了他建议的包列表，但我继续得到错误。仔细查看错误，我注意到gcc命令包含pgsql93文件：

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

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:

查看/ usr / include /我看到pgsql92 /但不是pgsql93 /。所以我看看安装了什么与pgsql相关的yum软件包，我注意到了这些：

postgresql92.x86_64 postgresql92-devel.x86_64 postgresql92-libs.x86_64 postgresql93.x86_64 postgresql93-libs.x86_64

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:

对我来说就像应该有一个postgresql93-devel，所以我试过：

sudo yum install postgresql93-devel

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.

这解决了我的问题！所以我猜主题是：看看gcc的调用，看看它是什么导入的。跟随那里的面包屑。

#6

In centos 7. i'd use sudo yum install postgresql96-devel.x86_64 to solved my problem.

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

#7

The invocation of gcc failed, gcc couldn't compile the source. Probably the cause is

gcc的调用失败了，gcc无法编译源代码。原因可能是

./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.

如果您拥有它，那么头文件libpq-fe.h在搜索路径中是无处可去的。

For Ubuntu 14.04, from Docker image python:3.4.3-slim this combination worked for me:

对于Ubuntu 14.04，来自Docker image python：3.4.3-slim这个组合对我有用：

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.

注意build-essential包。这对我来说至关重要。

For me, the missing package was

对我来说，丢失的包裹是

libpqxx-devel.x86_64

#10

This worked for me on Ubuntu Server 14.10 64-bit:

这在Ubuntu Server 14.10 64位上对我有用：

sudo apt-get install libpqxx-dev
