The invocation of gcc failed, gcc couldn't compile the source. Probably the cause is
gcc 调用失败，gcc 无法编译源代码。原因大概是
./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.his nowhere in the search path if you have it at all.
libpq-fe.h如果您有标题，则搜索路径中无处可寻。

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
你需要为 PostgreSQL 安装开发包，例如在 Ubuntu 下是一个sudo apt-get install libpq-dev......而对于 CentOS 它是yum install postgresql-devel

For the case of CentOS, I had this very same problem, that I solved installing these packages:
对于 CentOS，我遇到了同样的问题，我解决了安装这些软件包的问题：
sudo yum install postgresql-libs
sudo yum install postgresql-devel
sudo yum install python-devel
only then, I was able to perform successfully:

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 gcccommand was including pgsql93 files:
我一直在尝试在普通的 Amazon Linux EC2 实例上安装 pgsql，但一直出现此错误。根据 Nicolás 的回答，我安装了他建议的软件包列表，但仍然出现错误。更仔细地查看错误，我注意到该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

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:
看着/usr/include/我看到pgsql92/但没有pgsql93/。所以我查看了安装了哪些与 pgsql 相关的 yum 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:
在我看来应该有一个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.
这为我解决了问题！所以我想主题是：查看 gcc 调用，看看它拉入了什么目录。从那里跟随面包屑。
