Install packages using PIP in Python 3.3 on Windows - python-3.x

I have windows 7 with Python 3.3 installed. I also installed pip by referring to:
https://github.com/BurntSushi/nfldb/wiki/Python-&-pip-Windows-installation
I am facing issues with package installation-
If I run,
C:\Python33\Scripts> pip install requests
(OR)
C:\Python33\Scripts>pip install -U googlemaps
It does not give any success message like
'the package is installed'.
It is basically not showing any error/success message. Please refer below screenshot -
How can I install packages using pip, or how do I know if I have successfully installed packages?
TIA,
Sanket.

You can use pip show package_name to check whether the package is installed or use the pip list to view all installed packages.
Please follow the official website instruction to install pip or
Try reinstalling Python

How to install github python files which pip installation is not provided?

I want to install https://github.com/opendoor-labs/pyfin package in windows 10, but no pip installation method is provided in the page. I use vs-code python-3.9.10 and all my libraries are installed in a virtual environment. The git address of all files is https://github.com/opendoor-labs/pyfin.git. but I don't know how to download and install directly to the (venv). Is there any easy way to install and import it to my code? I tried 'pip install pyfin', but it installed other library included in this page : https://pypi.org/project/pyfin/ which is different.
First activate your venv.
(activate it using the .\venv\Scripts\activate command.)
The run pip install git+https://github.com/your/repo

Error installing psycopg2 on macOS with building wheel [duplicate]

I'm attempting to make a website with a few others for the first time, and have run into a weird error when trying to use Django/Python/VirtualEnv. I've found solutions to this problem for other operating systems, such as Ubuntu, but can't find any good solutions for Mac.
This is the relevant code being run:
virtualenv -p python3 venv
source venv/bin/activate
pip install -r requirements.txt
After running that block, I get the following errors:
AssertionError
Failed building wheel for django-toolbelt
Running setup.py bdist_wheel for psycopg2
...
AssertionError
Failed building wheel for psycopg2
Failed to build django-toolbelt psycopg2
I believe I've installed the "django-toolbelt" and "psycopg2", so I'm not sure why it would be failing.
The only difference I can think of is that I did not use the command
sudo apt-get install libpq-dev
as was instructed for Ubuntu usage as I believe that installing postgresql with brew took care of the header.
Thanks for any help or insight!
For MacOS users
After trying all the above methods (which did not work for me on MacOS 10.14), that one worked :
Install openssl with brew install openssl if you don't have it already.
add openssl path to LIBRARY_PATH :
export LIBRARY_PATH=$LIBRARY_PATH:/usr/local/opt/openssl/lib/
install psycopg2 with pip pip3 install psycopg2
I had the same problem on Arch linux. I think that it's not an OS dependant problem. Anyway, I fixed this by finding the outdated packages and updating then.
pip uninstall psycopg2
pip list --outdated
pip install --upgrade wheel
pip install --upgrade setuptools
pip install psycopg2
I was also getting same error.
Using Python 3.7.3 and pip 19.1.1.
I used following command.
pip install psycopg2-binary==2.8.3
TDLR
If you aren't used to installing Python C-extensions, and psycopg2 isn't a core part of your work, try
pip install psycopg2-binary
Building Locally
psycopg2 is a C-extension, so it requires compilation when being installed by pip. The Build Prerequisites section of the docs explain what must be done to make installation via pip possible. In summary (for psycopg 2.8.5):
a C compiler must be installed on the machine
the Python header files must be installed
the libpq header files must be installed
the pg_config program must be installed (it usually comes with the libpq headers) and on $PATH.
With these prerequisites satisfied, pip install psycopg2 ought to succeed.
Installing pre-compiled wheels
Alternatively, pip can install pre-compiled binaries so that compilation (and the associated setup) is not required. They can be installed like this:
pip install psycopg2-binary
The docs note that
The psycopg2-binary package is meant for beginners to start playing with Python and PostgreSQL without the need to meet the build requirements.
but I would suggest that psycopg2-binary is often good enough for local development work if you are not using psycopg2 directly, but just as a dependency.
Concluding advice
Read the informative installation documentation, not only to overcome installation issues but also to understand the impact of using the pre-compiled binaries in some scenarios.
I had same problem and this appears to be a Mojave Issue, I was able to resolve with:
sudo installer -pkg /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg -target /
For Mac OS X users:
1. First check your postgresql path by running this command in terminal:
pg_config
If this fails lookup how to add pg_config to your path.
2. Next install Xcode Tools by running this command in terminal:
xcode-select --install
If you have both those sorted out now try to install psycopg2 again
For MacOS users, this question has the correct solution:
install command line tools if necessary:
xcode-select --install
then
env LDFLAGS="-I/usr/local/opt/openssl/include -L/usr/local/opt/openssl/lib" pip install psycopg2
I was also facing the same after running all the above commands, but the following two commands worked for me:
Instead of pip, use this:
sudo apt-get install libpq-dev
then run this command:
pip install psycopg2
On OS X, I was able to solve this by simply upgrading wheel before installing psycopg2:
pip install --upgrade wheel
For OSX Sierra users, it seems that an xcode update is the solution: Can't install psycopg2 package through pip install... Is this because of Sierra?
I tried all the above solutions but they did not work for me. What I did was change the psycopg2 version in my requirements.txt file from psycopg2==2.7.4 to psycopg2==2.7.6
Is your error message complete? the most encountered reason for failing to install psycopg2 on mac from pip is pg_config is not in path.
by the way, using macports or fink to install psycopg2 is more recommended way, so you don't have to worry about pg_config, libpq-dev and python-dev.
plus, are using Python 3.5? then upgrage your wheel to > 0.25.0 using pip.
I faced the same issue, but the answers above didn't work for me.
So this is what I did in my requirements.txt
psycopg2-binary==2.7.6.1 and it worked fine
I had this issue on several packages, including psycopg2, numpy, and pandas. I simply removed the version from the requirements.txt file, and it worked.
So instead of psycopg2-binary==2.7.6.1 I just had psycopg2-binary.
I know you are asking for development environment but if you are deploying on server say, Heroku. Just add below line in the requirements.txt of your project.
django-heroku==0.3.1
As this package itself will install the required packages like psycopg2 on server deployment.So let the server(heroku) should take care of it.
sudo apt install libpq-dev python3.X-dev
where X is the sub version,
these should be followed by :
pip install --upgrade wheel
pip install --upgrade setuptools
pip install psycopg2
Enjoy !!!
I solved my problem by updating/installing vs_BuildTools. The link to the software was given in the error itself.

Fixed by installing python3.7-dev: sudo apt install python3.7-dev, based on the link.

problem in installing packages in miniconda 3

discription of the problem can be seen in the pictureI am using miniconda3 and it shows that no modules have been installed when I am accessing the module from Jupiter notebook.
I have installed the modules from miniconda prompt by pip install pandas,sklearn etc" the modules have been individually installed and it shows success full installation also, but when accessing it in jupyter notebook it shows error.
Did you install pip using conda install pip? You need to ensure that pip installs packages somewhere where miniconda looks for them. If you're installing common packages to be used inside conda, I'd recommend using the conda package manager to install them.

If anaconda has a package and it is not in pip, how do I install it?

I want to install gudhi packages.
It seems that the package only says that it can be installed only with anaconda. But I want to install it with pip , not anaconda.
When I checked the package, I found a zip file called tar.bz2, which I tried to install using it, but I can not figure out what to do.
And I do not know if this is the right way.
So I would like to seek advice.
Thank you for reading.
There is no pip install gudhi available.
If you don't want to go with conda, you will have to follow the installation guide.
If make cython works, you can then [sudo] python[3] setup.py install to install it on your system.
[EDIT]
A gudhi pip package is now available.

Error installing urllib3

I am using the command pip install urllib3, the error trace I am getting is as below.
Which pip version do you use?
Try first to run the command pip install --upgrade pip
After that, when your pip version is up-to-date try to install the urllib3.
EDIT:
Alternatively, you can grab the latest source code from GitHub:
git clone git://github.com/shazow/urllib3.git
python setup.py install
Without seeing the full traceback, this looks like your computer cannot resolve the addresses for pypi.python.org or pypi.org (I dont' know what version of pip you're using).
This could be because of a proxy issue or some other internet connectivity issue. There is literally no way for someone to help you debug this without more information.
Finally
pip install urllib3 version=2.4.0
Does not do what you think. What you told pip to do was install urllib3 and install a package named version. If you want a specific version you need to write
pip install urllib3===1.4.0
Or whatever version you need.
