I am new to programming and this is my first project
trying to start a django project on the server
activated virtual environment
after the pip install -r requirements.txt command, an error occurs
Exception:

Ok By watching at your problem i saw that there is a typo error in beautifulsoup4 library in requirements.txt file , and in comments as mentioned that u are also facing error in installing django
Could not find a version that satisfies the requirement Django==2.0.7 (from -r requirements.txt (line 3)) (from versions: (any versions) .No matching distribution found for Django==2.0.7 –
Django above 2 version support only python3 , so try
pip3 install django==2.0.7
if you have python3.5 and above in your system
Also to see supported versions by pip try:
pip install django==0
and
pip3 install django==0
make sure you are not using vpn.
What OS are you in? Make sure to have installed everything correctly, make the folders following official docs or maybe a tutorial, make sure to always use the right environment, in which Django has been properly installed via pip (I use pip3) Make sure before to have the latest version of Python supported (I use 3.8.2) and the latest version of pip. Make all the passages again and see what happens. If something goes wrong, be more detailed on what you've done.
Going over your problem again, I found that 2.0.7 indeed a correct version.
But in your requirements.txt its written as Django==2.0.7 that should be django==2.0.7

I have a program where I dearly need the dependency list, but pip freeze isn't working. I am running CentOS 7 and Python 2.7.5
The program runs on Python 2.4 (which I am doing as an alias in another terminal, yes, I did try the pip freeze from that terminal) and fortran95. I definitely have pip installed. I tried upgrading the Python2.7, but it says it is fine.
The the error from pip is as follows.
[root#localhost rotate6]# pip freeze

This is a known issue. See https://github.com/pypa/pip/issues/3764
The advice there is to try downgrading your version of pip to one that is less strict (some people find 8.1.0 works), or to uninstall the offending package, which appears to be _ipap11helper.
I have Django 1.9.7 installed, and its works fine, but every time I open the terminal, I get this message.
If Python could not import the module virtualenvwrapper.hook_loader,
check that virtualenvwrapper has been installed for
VIRTUALENVWRAPPER_PYTHON=/usr/bin/python and that PATH is
set properly.
When I startproject in Django, it works fine. I wonder whether this will cause problems in the future, and how can I fix it?
I speculate that it is causing this problem because I used to use Python 2.7 with Django 1.9.7. I have recently upgrade by python to 2.4, but it seems that my packages for python 2.7 still exist in my computer. However, when I tried removing the python 2.7 packages with pip uninstall python == 2.7, I get this error

I have read that it is not good to uninstall packages using pip because it does uninstall everything, but I am not sure how else to do it, and I am not sure how to fix the module issue either.
Any ideas? I don't have Python in the path & the company won't allow it. I wouldn't expect it to make a difference to a well written installer, but mention it just in case.

Despite this post was asked 3 months ago, I faced the same issue today. I found a solution in the end so I would like to share it here. Hope it is still useful.
I found in another post here:
https://www.quora.com/I-tried-to-install-PyWin32-for-Python-2-7-at-Python-for-Windows-Extensions-but-it-did-not-work-How-can-I-install-PyWin32
to install from the wheel distribution instead.
In case you have the same connection problem with pip like me, please download the source of wheel via its git repo:
https://bitbucket.org/pypa/wheel/downloads (choose the version you like, latest probably best). Then install it using
pip install <<_path_to_the_zip_file_downloaded_>>
I've a project in Django which I'm trying to port to Django-nonrel so that I can upload it to Google app Engine. I've installed django-nonrel and other required libraries by going through the http://djangoappengine.readthedocs.org/en/latest/installation.html
namely: django-nonrel
djangoappengine
djangotoolbox
django-autoload
django-dbindexer
that is by downloading their zip files and placing them in my app directory.
So, my app directory is:
>
<app>/autoload
<app>/dbindexer
<app>/django
<app>/djangoappengine
<app>/djangotoolbox
I also have django in my project directory and have started the project by:
PYTHONPATH=. python django/bin/django-admin.py startproject \
--name=app.yaml --template=djangoappengine/conf/project_template app
If I am adding an external library with pip and adding it to the INSTALLED_APPS of my app's settings.py , it is not recognised by my django-nonrel which is pretty obvious considering the fact that django-nonrel is not installed on my system. It gives me the following error

However, I'm unsure on how to add external libraries to my project. So that my django-nonrel recognises it. I've also tried google's documentation on how to this i.e.
Adding Third-party Packages to the Application
You can add any third-party library to your application, as long as it
is implemented in "pure Python" (no C extensions) and otherwise
functions in the App Engine runtime environment. The easiest way to
manage this is with a ./lib directory.
Create a directory named lib in your application root directory:
mkdir lib To tell your app how to find libraries in this directory,
create (or modify) a file named appengine_config.py in the root of
your project, then add these lines:
from google.appengine.ext import vendor
£ Add any libraries installed in the "lib" folder. vendor.add('lib') Use pip with the -t lib flag to install libraries in this directory:
$ pip install -t lib gcloud Note: pip version 6.0.0 or higher is
required for vendor to work properly.
Tip: the appengine_config.py above assumes that the current working
directory is where the lib folder is located. In some cases, such as
unit tests, the current working directory can be different. To avoid
errors, you can explicity pass in the full path to the lib folder
using
vendor.add(os.path.join(os.path.dirname(os.path.realpath(file)),
'lib'))
didn't work either.
So I had a very similar dilemma. Here is how I solved it:
Followed Google's instructions noted above, using pip and a ./lib directory. Make sure you have an updated version of pip:
sudo pip install --upgrade pip
Then, because of pkg_resources issues, I did this:
pip install -t lib setuptools
That was necessary, I am just not sure if that was the right place to install setuptools or not. It certainly worked, though.
Then, I launched the local development server like this, in the project directory:
PYTHONPATH=lib ./manage.py runserver
I hope that works for you!
I 'm not able to install python packages from both pip and easy_install. There's some absurd kind of error that keeps popping up. Kindly help to rectify it.
I get the same errors while using python setup.py install.

Find get_entry_map(self, group=None): into python\Lib\sitepackages\pkg_resources\__init__.py. Insert after print self.egg_info

Remember it, later to install again. Delete the folder of broken
package and folder broken_package-version.dist-info. Run again paragraph 2, until the error disappears.
Remove changes from paragraph 1.
python setup.py install 'broken_package'
This error happened to me installing any package. My solution was going to my file explorer, typing in the path bar %appdata%, going to the Python folder, and deleting everything inside.
I found the same problem to be caused by a misfometted entry_points.txt file in one instelled egg of mine.
It can be quite hard to track down which one is if there are many.
I managed to find that little ba##!"d by creating and run setup.py for a dummy package:
setup.py
from setuptools import setup, find_packages
setup(
name = "IWillFindYou",
version = "0.1",
packages = find_packages()
)
run this in debug mode would point to this line in pkg_resources.py
def parse_map(cls, data, dist=None):
[...]
raise ValueError("Entry points must be listed in groups")
if you go back to the stack trace, you will see that parse_map is called here:
def get_entry_map(self, group=None):
[...]
ep_map = self._ep_map = EntryPoint.parse_map(
self._get_metadata('entry_points.txt'), self
)
evaluating self.egg_info will point up your evil egg so you can give a look to the entry_points.txt file.
If you are not handy with debugger, you may try to place print self.egg_info in get_entry_map and look to the last guy printed.
My Resolution Approach
Platform: windows 10, ConEmu-Maximus5
Delete virtual environment automatically created by poetry install command.
windows users can find the virtual environment folder in the path below
C:\Users\YOUR_PC_USERNAME\AppData\Local\pypoetry\Cache\virtualenvs
(don't know of linux path)
close terminal / command prompt
open terminal / command prompt and navigate to project folder
re run poetry install
I hope it helps...
How i encountered the error
It was my first time using poetry, while running poetry install, the process got interrupted. running the command again popped out the error.
Could be a problem with distribute. I'd recommend re-installing Python.
