Python installing private github repo giving "exit status 128" error?

I am on Windows 10 running Python 3.7.
I am trying to install a Python package on one of my private GitHub repositories. I want to use the GitHub deploy key to give only read access to the single repository.
So I generated the deploy key using
ssh-keygen -t rsa -b 4096 -C "email#domain.com"
This added the private and public key to the .ssh folder on my user machine. I then copied the public key to the deploy keys for my private GitHub python package repository.
Then I generated a virtualenv and tried to run the command
pip install git+ssh://git#github.com/<github_username>/<repo_name>.git
but I keep getting an error saying
ERROR: Command errored out with exit status 128: git clone -q 'ssh://****#github.com/<github_username>/<repo_name>.git' 'C:\Users\Alex\AppData\Local\Temp\pip-req-build-doj1og3o' Check the logs for full command output.
I've looked at other posts with the similar issue and as far as I can tell my syntax for the installation command is correct.
Here is my error log output:

Hello I had this same exact problem!
I found the answer on:
https://docs.github.com/en/authentication/troubleshooting-ssh/error-permission-denied-publickey
It turns out that I needed to ensure that my ssh key was being used. I did so by following the directions on the github site which suggested that I run this command:
ssh -vT git#github.com
I ran this command prompt and It worked! I don't know how or why but it seems to have reset some sort of configuration to where my ssh shell now works. I'd tried all sorts of different solutions and was getting very discouraged about it because my linux setup worked fine! It was windows 10 that seemed to be giving me trouble.
After that I was able to pip install from github using the powershell inside of vscode (with a venv enabled).
I originally thought that the issue was my sshkey (that I'd pasted it wrong) but that wasn't the case. I also thought it might have been something with visual studio code but that wasn't the case either. Then I thought it might have been something with my security protocols. SO I tried enabling and disabling different ports through my firewall that were suggested in other forums and that didn't work either.
I knew something was up because whenever I created a key on my Desktop it would never show any activity of use when I viewed my keys on Github. But as soon as I ran the command a green light appeared and showed that it was recently activated. I have 2 ssh keys enabled (laptop and desktop) for my private repo and use it to pip install packages from there.
I hope this helps somebody out there! Sorry if I spoke too much. This is my first post. I just found this solution and had to share it because I was so excited!

Docker build failing while installing pandas in docker in python2.7-alpine

I am running a flask application in Docker. I am also using Pandas. I am using python2.7-alpine image. Earlier it was working fine i.e. I was able to build images with the same configuration.
But now I am unable to build the image as it says:
ERROR: Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-install-Sm9A7D/pandas/
The command '/bin/sh -c pip install -r /tmp/requirements.txt' returned a non-zero code: 1
I cannot change the python version. As my application is built on python2 and was as expected for a long back.
My Dockerfile

----------------------------------------
ERROR: Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-install-Sm9A7D/pandas/
The command '/bin/sh -c pip install -r /tmp/requirements.txt' returned a non-zero code: 1

The error tells you the reason:
File "/tmp/easy_install-r9No9Q/numpy-1.17.0rc1/setup.py", line 31, in
def is_platform_mac():
RuntimeError: Python version >= 3.5 required.
From pandas 0.23.4 source: we can see the minimum version for numpy is 1.9.0:
min_numpy_ver = '1.9.0'
So, if you did not install a version by yourself, pandas will just install a newest suitable version of numpy which >1.9.0 for you, here is numpy-1.17.0rc1, but it needs >python3.5 as seen here, so failure happens.
python_requires='>=3.5'
Finally, if you check the source code of numpy, you will find 1.16.4 is the last version which support python2.7, see this,
python_requires='>=2.7,!=3.0.*,!=3.1.*,!=3.2.*,!=3.3.*',
So, final solution:
Pre-install numpy 1.16.4, then pandas find there is a suitable numpy there, and will not install a newest numpy for you. As a result, no error will happen, detail steps as next:
apk update
apk add build-base
pip install numpy==1.16.4
pip install pandas==0.23.4
For Dockerfile, add above command to one RUN could make the fix:
RUN apk update && \
apk add build-base && \
pip install numpy==1.16.4 && \
pip install pandas==0.23.4
Additional, you said in question:
Earlier it was working fine i.e. I was able to build images with the same configuration.
This is because numpy latest version was just updated July.1st 2019, before that, it always 1.16.4 version which don't have issue for python27, but now, things changed...

dev_appserver fails to launch on Ubuntu docker container (ValidationError: Value 'None' for application does not match expression)

I started seeing this issue after upgrading docker container. I couldn't find a way to use an older package for app engine. Using options =157.x.y to get older versions doesn't work in apt-get.

My version of dev_appserver started doing the same.
I dug onto the code and found that the argument parser sets an empty app_id command-line argument to "None" (yes, that's a String not a NoneType). Incidentally, the app_id regex does not match for uppercase characters and thus the ValidationError triggers. (I'm glad that's the case or else it would've caused trickier bugs by silently making my application's name 'None')
My workaround for now is to explicitly pass in the name of your application from the command line with the -A flag. Note that this overrides the application variable in the app.yaml configuration.
I was thinking my version of argparse was broken but now it sounds like a dev_appserver bug.

I'm going to guess that the problem lies in the message:
settings.DATABASES is improperly configured. Please supply the NAME value.
The installation has failed.
I'm using PostgreSQL, so I assume that the error is caused by the schema not being provided in the command argument. There was nothing in the guide that I saw indicating how to provide it, so I'll have to search some more.

The error message tells me absolutely nothing. It only tells me that Django tried to use pip to install something and for whatever reason it failed. In order to figure out what went wrong, try enabling verbose mode (python -v). If that gives the same output, or that isn't an option because you're using a program that calls Python (which it sounds like you are), let me know and prepare to go into the source code. Trust me, I have taken many a dive into source code for Python utilities, and as long as you don't do anything stupid (like delete a file) it's pretty hard to mess anything up. Even if you do you can always reinstall Django (or make a backup first). Don't worry about messing up your computer. You'd have to work hard to make Django do that!

Original error
The non-verbose error message indicates the error in a cryptic way, and using --verbose provides a more understandable message.
I was missing one required module (psycopg2) and four others were versions which were too new (easy_thumbnails, Django, html5lib, django-select2).
I uninstalled the four modules and then reinstalled them using the version requirement in the command. e.g. pip install 'Django<1.10'.
psycopg2 required extra steps, as I got an error message when trying to install it indicating that it could not find pg_config. Another SO answer advised that I just had to install postgresql-devel. After I did that, (sudo yum install postgresql-devel), I also uninstalled postgresql8-libs, as postgresql-devel came with a newer version. I didn't do it before since yum indicated a PHP dependency, and I wasn't sure if it would cause problems if I did.
Second error
Pretty simple. I was missing the /NAME component of the database URL (postgres://USER:PASSWORD#HOST:PORT/NAME).

Issues in Installing Python packages in webfaction

I am trying to install packages using PIP but it doesn't work for me initially it gives the permission denied error and after that when I tried to use easy_install it gives me this error :->

Now I don't know what I am doing wrong , can anybody help me ?
EDIT :- syntex errro solved due to wrong python version , I was using 2.4 .

$which pip result is
~/bin/pip

Just add the --user option to your pip command, it will install with your logged in user permissions:
pip2.7 install mezzanine --user

as Daniel Roseman noted - the syntax error came from using Python2.4
the permission problem is caused by trying to install into system Python, what requires sudo or being root
Possible solutions
Install into system Pyhton (using sudo)
$ sudo pip install mezzanine
This will spoil the system Python and is not much recommended. It would be well acceptable if you are e.g. under Docker.
Install into user profile
$ pip install --user mezzanine
It will install the package into user scheme and will not spoil system Python.
This is more acceptable, but can soon become messy environment to run code in, as Python will import form user scheme, sometime from system.
Use virtualenv
Assuming you have virtualenv installed:
$ cd ~/projects
$ mkdir mezza
$ cd mezza
$ virtualenv venv
$ source venv/bin/activate
(venv)$ pip install mezzanine
$ pip freeze
mezzanine==3.1.8
(there will be a bit more lines from freeze).
This installs into virtualenv, which is easy to recreate, destroy, and does not mess up with other environments.
With virtulanevwrapper you will get set of additional tools, which will simplify your environment a lot.
