I installed python2.7 on my

centos 2.6.32-431.17.1.el6.x86_64

following these directions:


#after the yum stuff...
# Python 2.7.6:
wget http://python.org/ftp/python/2.7.6/Python-2.7.6.tar.xz
tar xf Python-2.7.6.tar.xz
cd Python-2.7.6
./configure --prefix=/usr/local --enable-unicode=ucs4 --enable-shared LDFLAGS="-Wl,-rpath /usr/local/lib"
make && make altinstall

I am trying to install psycopg2:

[stuff]# pip2.7 install psycopg2
./psycopg/psycopg.h:31:22: error: libpq-fe.h: No such file or directory

Upon researching, that means I need to install python-devel (I think), but I can't install this because it would install for my 2.6 default on the system.

I tried to install from source:

[stuff]# python2.7  ./external_dependancies/psycopg2-2.5.3/setup.py install
Traceback (most recent call last):
  File "./external_dependancies/psycopg2-2.5.3/setup.py", line 474, in <module>
    use_pydatetime  = int(parser.get('build_ext', 'use_pydatetime'))
  File "/usr/local/lib/python2.7/ConfigParser.py", line 607, in get
    raise NoSectionError(section)
ConfigParser.NoSectionError: No section: 'build_ext'

What do I need to do to get python-devel (or better yet, psycopg2) on my system

  • why not using pip and virtualenv to install a specific version of python in a directory? – Braiam Jul 17 '14 at 19:48
  • I'd still need the python-devel, right? Isn't that a system package, not a python environment package? – Jeff Jul 18 '14 at 0:44

I was missing this package:
