How to install Psycopg2 for Python 3.5

I am trying the following command on Windows 7 using powershell

pip install psycopg2

And i am getting an error:

error: Microsoft Visual C++ 14.0 is required (Unable to find vcvarsall.bat). Command "C:\Users\Piyush\AppData\Local\Programs\Python\Python35\python.exe -c "import setuptools, tokenize;file='C:\Users\Piyush\AppData\Local\Temp\pip-build-qe38dwoj\psycopg2\setup.py';exec(compile(getattr(tokenize, 'open', open)(file).read().replace('\r\n', '\n'), file, 'exec'))" install --record C:\Users\Piyush\AppData\Local\Temp\pip-7bjug79j-record\install-record.txt --single-version-externally-managed --compile" failed with error code 1 in C:\Users\Piyush\AppData\Local\Temp\pip-build-qe38dwoj\psycopg2

To intall Visuall C++, it requires Visual Studio to be installed. Except for installing Visual Studio 2013. Is there any other, that I can install Psycopg2 for Python 3.5??

In my case this error was occurring because the python path was not in environment variable. You can verify by typing python/python3 in your cmd and if the python shell is starting or not.

These different methods also worked for me at different times:

  • check python path in environment variable.
  • installing visual c++ 14 or latest.
  • reinstalling python.
  • installing binary or psycopg2 instead.
  • install via easy_install.
  • check by installing in global environment instead of virtual environment.
  • try different psycopg2 version whl file. https://www.lfd.uci.edu/~gohlke/pythonlibs/#psycopg

For Linux/Mac based you need to first install:

sudo apt-get install python3-dev

and then install psycopg2:

pip install psycopg2

For me it worked in DigitalOcean Linux 16.04 Production server

Let me know if anyone got this correct!

Try this one. It worked for me

I Visited the http://www.lfd.uci.edu/~gohlke/pythonlibs/ and downloaded psycopg2-2.6.1-cp35-none-win32.whl file and copied it on C:\

later I activated my Virualenv by running this C:\mydjango\django19\Scripts\activate on the cmd which resulted to this (django19) C:/> and ran the following pip command, pip install psycopg2-2.6.1-cp35-none-win32.whl and the installation was successful.

Note: Run the pip install psycopg2.......whl when you are in the current folder that has the psycopg2-2.6.1-cp35-none-win32.whl file via cmd

I ran into a similar issue on Windows. I had to install a compiled version of it and then easy_install it.

You can find a compiled version of psycopg2 here: http://www.lfd.uci.edu/~gohlke/pythonlibs/

And then do easy_install C:/locaiton/of/download.exe

That's what I do to install it on my Windows machine.
