Cannot install "psycopg2" on Windows 10 with Python 3.8

Yesterday I uninstalled python 3.7 version by mistake. Then I install python again (this time 3.8 version) and again set up my environment. But I could not start my Django project which has Postgres connection. Actually I cannot install "psycopg2" in my environment. I searched for hours and implement every solutions I get from online but it does not work. Let me tell you what I did so far.
First it said to add Postgres in my PATH so I added C:\Program Files\PostgreSQL\12\bin\ in my PATH.
A new problem then arise with a huge ERROR report with 2 vital Error.
ERROR: Failed building wheel for psycopg2
..........................
Running setup.py install for psycopg2 ... error
I try to upgrade wheel but it says,
Requirement already up-to-date
http://initd.org/psycopg/docs/install.html#install-from-source
I learned from this site that psycopg2 requires python2 version. So I installed python 2.7 also.
I reinstalled PostgreSQL but it does not work.
I deleted my virtual environment and create again but it does not work.
Some says they solve this problem by running pip install psycopg2-binary But it does not work for me.
Please help me to get rid of this. I stuck for hours.
When you asked this question, Python 3.8 had been released very recently so there were not any wheels for Python 3.8 yet.
At the time, my suggestion was to install Python 3.7.X and install the binary wheel with:
pip install psycopg2-binary
Since then, binary wheels have been released for Python 3.8, so the above command should work with Python 3.8.X as well.
I wouldn't try to build from source on Windows if it can be avoided.
Finally, you misunderstood the section of the docs about Python 2. You only need Python 2.7 if you are running Python 2. For Python 3, which you should be using for all new projects, it currently supports Python 3.4 to 3.8.
use:
sudo apt install python3-dev libpq-dev
then try doing:
pip3 install psycopg2
Hope it works for you!!
This problem mainly occurs due to this -- " error: Microsoft Visual C++ 14.0 or greater is required. Get it with "Microsoft C++ Build Tools": https://visualstudio.microsoft.com/visual-cpp-build-tools/"
Now to install psycopg2, first you need to install visual studio from Microsoft - https://visualstudio.microsoft.com/visual-cpp-build-tools/
now you need to install the c++ desktop development tool with all its default components selected.
After successful visual studio c++ desktop development kit installation, you can now install psycopg2 successfully in your machine.

virtualenvwrapper -- Opencv 3.1.0 installation error

I am trying to install opencv 3.1.0 by the help of following blog(Why? Because I followed the same blog to install opencv in Desktop, but In my Laptop, following issue came)
Here I encountered the following error as --
ujjal#ujjaldas223:~$ source /usr/local/bin/virtualenvwrapper.sh
/home/ujjal/anaconda2/bin/python: No module named virtualenvwrapper
virtualenvwrapper.sh: There was a problem running the initialization hooks.
If Python could not import the module virtualenvwrapper.hook_loader,
check that virtualenvwrapper has been installed for
VIRTUALENVWRAPPER_PYTHON=/home/ujjal/anaconda2/bin/python and that PATH is
set properly.
I followed the link, but failed to resolve issue.
Suggest me how to solve this error.
I am using ubuntu 16.04 LTS both in Desktop and laptop.
I just solved it!
The problem was anaconda path appended to python.
Removing anaconda2 completely solved the issue.

How to install difflib module in python 2.7 windows 10

Currently, I am facing difficulty installing difflib module in python 2.7 version in windows 10 system.
I want it to perform some text analytics analysis
tried using
apt-get install npm
npm install difflib
and
pip.exe install difflib
Solution for me was to save the difflib.py in the location where your .py file resides and then import it in your file.
install using pip should be a great idea, You can refer to the module related details here:
https://docs.python.org/2.7/library/difflib.html
If you face an issue installing it using pip, then the next way is to get the difflib.py from any working machine and keep it in the project directory itself, so that just importing the module itself will work.
This is the codebase reference from svn of python itself:
https://svn.python.org/projects/python/trunk/Lib/difflib.py

How to add theano to anaconda python v2.7 on ubuntu 16.04?

I'm want to install theano into the anaconda package for python v2.7 on ubuntu 16.04. I already installed anaconda to the folder /opt/anaconda. Can some please guide me on how to install Theano package which is accessible by the anaconda packages. I've searched lot on google but not able find a clear solution to the problem.
I was recommended to switch back to 14.04 for theano, because t just stopped working on 16.04, but still I am also looking for a solid working guide.
There are some resources that explain how to set up these http://deeplearning.net/software/theano/install_ubuntu.html

installing pygame over anaconda

I am trying to install pygame over anaconda. My OS is windows 7 64 bit and I downloaded the following files:
pygame-1.9.2a0-cp27-none-win32.whl
pygame-1.9.2a0-cp27-none-win_amd64.whl
prebuilt-x64-pygame-1.9.2-20150907.zip
pygame-1.9.2a0-hg_ea3b3bb8714a.win32-py2.7.msi
pygame-1.9.2a0.win32-py2.7.msi
I get this error after "pip install pygame":
Could not find a version that satisfies the requirement pygame (from versions: ) Some externally hosted files were ignored as access to them may be unreliable (use --allow-external
What am I missing?
Thanks
This worked for me when installing pygame with anaconda. I believe that if you go into the terminal on anaconda and type
Pip install pygame
It installs the latest version of pygame into your environment
