Installing requirements.txt throws an error on Django

The project was working perfectly until recently when I created a model for my database and tried to pip install requirement.txt. I have done everything I know including modifying my settings.py to add the missing library, reinstalling django and psycopg2, all to no avail. Here's my requirement.txt:

tweepy==3.8.0
django
gunicorn
django-heroku

The error i'm getting:

 ld: library not found for -lssl
    clang: error: linker command failed with exit code 1 (use -v to see invocation)
    error: command 'gcc' failed with exit status 1

After long hours of searching and experimenting, I finally was able to solve the problem. But I'm still investigating on what really could have caused the error. Anyways, here's what fixed it

export LDFLAGS="-L/usr/local/opt/openssl/lib"
export CPPFLAGS="-I/usr/local/opt/openssl/include"
pip install psycopg2

I found it here: error installing psycopg2, library not found for -lssl

You need to reinstall gcc , gcc-c++ and dependencies.

For python 2.7

$ sudo yum -y install gcc gcc-c++ kernel-devel
$ sudo yum -y install python-devel libxslt-devel libffi-devel openssl-devel
$ pip install "your python packet"

For python 3.4

$ sudo apt-get install python3-dev
$ pip install "your python packet"

Hope this will help.

Based on the error message, you need to install the openssl-devel package on your system.
