I am trying to host a Django app on Heroku. The app works fine on my computer as long as I don't use django-heroku (because I can't install it), and it works fine on Heroku as long as it does have django-heroku. This is not a pressing issue, but it is sort of annoying to have to remove django-heroku to make edits on my computer, and then have to re-insert it before pushing to heroku.
The ideal solution would be to get django-heroku installed on my computer.
Specifications:
Mac running macOS
Conda environment, python 3.7 and 3.8
Here is what I have found so far:
pip 20.0.2 from /Users/lucas/opt/anaconda3/lib/python3.7/site-packages/pip (python 3.7):
Cannot install django-heroku (See error below)
pip 20.1.1 from /Users/lucas/Library/Python/3.7/lib/python/site-packages/pip (python 3.7):
Can install django-heroku, however:
Gives me this warning: (still installs without any problems)
WARNING: pip is being invoked by an old script wrapper. This will fail in a future version of pip.
Please see https://github.com/pypa/pip/issues/5599 for advice on fixing the underlying issue.
To avoid this problem you can invoke Python with '-m pip' instead of running pip directly.
running the script with all pythons in the environment say no module called django_heroku
The first version of pip I specified that couldn't install django-heroku gives this error:

I'm not an expert on how things like this work, so I included as much information as I could. I appreciate any help you can give on this.
First, django-heroku is no longer maintained, so my advice is to not use it.
Your problem, though is with psycopg2, as the error mentions, not django-heroku directly. Since django-heroku depends on psycopg2, installing psycopg2-binary probably won't help - and there can be issues with this as well, it's not suitable for serving your site from, although you're probably not doing that on OS X.
To get it working, you need to install the PostgreSQL libraries:
brew install postgresql
Depending on a few things, you may also have problems after that. If you see any errors about gcc and ssl, you can try running:
setenv LDFLAGS "-I/usr/local/opt/openssl/include -L/usr/local/opt/openssl/lib"
For fish, or if you running bash:
export LDFLAGS="-I/usr/local/opt/openssl/include -L/usr/local/opt/openssl/lib"
It can be tricky, so that may not be enough.

How to fix that?
The following will install prebuilt binaries for windows. It's worked for me on 3.9. You can uninstall pipwin after install psycopg2.
pip install pipwin
pipwin install psycopg2
Optional after psycopg2 installed:
pip uninstall pipwin
if u use linux
You need to make sure that you install wheel model
and Try that
sudo ./venv/bin/python -m pip install wheel
after that install psycopg2 and psycopg2-binary
sudo ./venv/bin/python -m pip install psycopg2
sudo ./venv/bin/python -m pip install psycopg-binary
I want to install pygame on python. I have ubuntu 20.04 (which has python3.8 already installed) and Anaconda.
pip is connected to Anaconda: which pip shows it's at /home/mohammad/anaconda3/bin/pip.
I use pip to install pygame on Anaconda. But pip install pygame shows error. How can I install pygame on Anaconda?
I can simply install pygame by deactivating Anaconda Enviroment and using pip which installs it on system python (It shouldn't have any problem). But I want to have pygame on Anaconda.
I don't really know where the problem is.

The main problems seems to be
Error: SWIG failed. Is Open Babel installed?
You may need to manually specify the location of Open Babel include and library directories. For example:
python setup.py build_ext -I/usr/local/include/openbabel-2.0 -L/usr/local/lib
python setup.py install
I see many people had similar issues with setup.py and they are advised to go to the directory and run the same command again, but I don't know what directory I should go to...
EDIT
Would it work if I download openbabel from github and give the path to it?
From my experience, instead of pip install <package_name>, download a wheel file from here which has python binaries built from source code found on PyPI.
After that, open a terminal where you downloaded .whl files and then type :
pip install nameOfYourFile.whl
in my case it's :
pip install openbabel-3.1.1-cp38-cp38-win32.whl
EDIT: be sure to download a version matching your python version otherwise the package will not install.
EDIT2:
I honestly didn't notice that the answer is focused on Linux, so to answer your question, your most reliable option is to build it from source with the python bindings and swig flags enabled, this can be done by following the compiling instructions.
Those instructions still work for the latest version of openbabel in the GitHub repo as of the date of this edit, and i could successfully compile a working openbabel with the python bindings (pybel) on Ubuntu 21.10.

To avoid this build problem with Jenkins, what I did is install the old cx_Oracle version under the default python site packages. I use virtualenv so I can create a virtual environment and basically tell it to inherit the default python site packages like this:
mkvirtualenv --system-site-packages env_name
So this environment will have access to the default cx_Oracle package. Since the requirement will already be satisfied, pip will not try to install it again when building in Jenkins.
I would love to upgrade a lot of things but it's just not seen as priority as long as everything works.

pip install is notoriously non-windows friendly. Either go to openbabel website and download + install windows binary, then download + install python binding, or use the unoffical official openbabel python windows build, then cd into the downloaded directory, and perform pip install OPENBABEL_FILE_WINDOWS.whl
I recently had do some quite a bit of work on 2D mol file -> 3D mol file translation using openbabel. Let me know how it works out for you.

edit: I should also add, python3.x is breakingly different to python2.x. So if anything breaks, try it with python2.x
This is somewhat old, but the problems still persist so i'll answer nonetheless.
The precompiled Windows binary (most likely) doesn't come with SWIG built-in, which in turn doesn't offer language bindings and gives you the error when installing from pip.
A workaround to this is to install a wheel from the unofficial Windows binaries website just like pandamakes answered.
However, the wheels already comes bundled with a precompiled obabel, so you really don't need to install the windows binaries version (the one that comes with the setup and all), but you have to know that if you're willing to ship a python script that uses this library, know that it will interfere with systems that do have BABEL_DIR in the environment variables, to fix this you have to include the whole openbabel directory from YourPythonDirectory/lib/site-packages/. in your script's folder.
Another important note is that some babel builds from the unofficial binaries website have a bug where they do not detect all file formats, especially the most common ones like sdf/pdb/mol2 or even smiles. The only versions i have confirmed working somewhat flawlessly so far are the openbabel‑3.1.1‑cp36‑cp36m‑win32.whl and openbabel‑3.1.1‑cp38‑cp38‑win32.whl.
