error at installing requirements.txt

[Mirabis]

Whenever I try to install the requirements I get:

Command "/usr/bin/python -c "import setuptools, tokenize;__file__='/tmp/pip-buil d-CBf1KO/psycopg2/setup.py';exec(compile(getattr(tokenize, 'open', open)(__file_ _).read().replace('\r\n', '\n'), __file__, 'exec'))" install --record /tmp/pip-M gq0ua-record/install-record.txt --single-version-externally-managed --compile" f ailed with error code 1 in /tmp/pip-build-CBf1KO/psycopg2

Are you using a Debian based system, if so have you installed the libpq-dev package? If you're using a Mac you will need to brew install postgresql for the header files.

[Mirabis]

Python 2.7.9 and pip 7.1.0 on Debian 3.16.0-4-amd64

[nickjj]

Sorry, I edited my comment to ask for different info. Can you sudo apt-get install libpq-dev and then try running pip install?

[Mirabis]

E: Unable to locate package libqp-dev

[nickjj]

Oops, libpq-dev.

[Mirabis]

hehe ;p

libpq-dev is already the newest version.

[nickjj]

What happens if you just pip install psycopg2? Also can you paste the error it dumped?

[Mirabis]

Okay, will try again on fresh install

Threw an error on psycopg2

[nickjj]

You may want to ping the author of psycopg2 or post an issue in his repo because at this point this is beyond the scope of the saas app.

It hints that you might be missing GCC on your machine. Have you done a apt-get install build-essential?

[Mirabis]

It's a fresh vm so hmm don't think I installed build-essentials ;o will try that later

[Mirabis]

Gave it a few more tries, ended up needing:

sudo apt-get install python-setuptools python-dev build-essential python-psycopg2

(build-essential) alone was not enough

[nickjj]

Ok thanks. I don't think python-psycopg2 is needed tho. We're installing it through pip.

Also would you mind providing the exact distro of Linux you're using, Debian 3.16.0-4 is probably just the kernel version.

[Mirabis]

No longer have the vm, as some ghost process spawned ;S

Debian 8 / Jessie , don't remember much more :(

[nickjj]

Ok thanks, Jessie is enough information.
