Error installing pscopg2 - python-3.x

I have OS X Sierra and I'm trying to install psycopg2 version 2.6.2 within a virtual environment using virtualenv and Python 3.4. On the step "Running setup.py install for psycopg2" I get this error message:
ld: library not found for -lssl
clang: error: linker command failed with exit code 1 (use -v to see invocation)
error: command '/usr/bin/clang' failed with exit status 1

I found that installing psycopg2 version 2.7.3.1 fixed the problem. So this bug must have been fixed in version 2.7 and above:

I am running a meteor project requiring the node.js version 14.17.3 but running the command nvm install 14.17.3 throws an error. It's strange because I used the same command to download version 14.13 with no issues.

Either follow theses steps Python, installing clarifai --> VS14.0 link.exe failed with exit status 1158

Cannot install tesserocr

I try running pip install tesserocr and I get the following error...
error: 'cinttypes' file not found
#include // PRId32, ...
^~~~~~~~~~~
1 error generated.
error: command 'gcc' failed with exit status 1
Failed building wheel for tesserocr
I've searched the entire web. I even tried compiling the source code and then running pip install . but this gave me the exact same error. How can I fix this?
there are various questions like this topic.
tesserocr is compiled during installation so you have to install also the development packages needed.
Which these are depends on your OS distribution

Installing OpenCV on Node problems

I have installed all the dependencies and have all compilers installed etc. Then when I finally try to install OpenCv in Node.js with Node Package Manager, I get the following error:
/bin/sh: pkg-config: command not found
gyp: Call to 'pkg-config --cflags opencv' returned exit status 127. while trying to load bind
Has anyone had the same problem?

Python 3 cx-Freeze install

I tried to install cx_freeze, but when I run sudo python3 setup.py build I get an error:
/usr/bin/ld: cannot find -lffi
collect2: ld returned 1 exit status
error: command 'gcc' failed with exit status 1
I know that I can install it using synaptic but that installed cx_Freeze into Python 2.6 but I need cx_Freeze for Python 3. I use Ubuntu 10.04
Sounds like libffi isn't installed. Try:
sudo apt-get install libffi-dev
