I'm trying to create a new environment and install various 3rd party packages on an Ubuntu machine. After having to install condo (for a matplotlib installation) and gdal, the pip function no longer works. Instead I receive:
Traceback (most recent call last):
File "/media/imagery/ENVIRONMENTS/Project_1/bin/pip", line 7, in <module>
from pip._internal import main
File "/usr/lib/python2.7/dist-packages/pip/__init__.py", line 14, in <module>
from pip.utils import get_installed_distributions, get_prog
File "/usr/lib/python2.7/dist-packages/pip/utils/__init__.py", line 30, in <module>
from pip._vendor.retrying import retry
ImportError: No module named retrying
I've called pip both in and outside my environment, and still observe the same issue. Also I've tried a pip install --upgrade pip and still retrieve the same Traceback. Any ideas how to resolve this?
As a cheap workaround, export PYTHONPATH=" " seemed to work for now in order to install other packages, but as soon as I need the gdal package, I have to then set PYTHONPATH again.
I had a similar exception and could manage to repair it.
In my case I upgraded Ubuntu 16.04 to Ubuntu 18.04.
I had to re-create the virtualenv. Depending on your choice:
virtualenv .
Or
virtualenv --system-site-packages .

I installed spyder on my ubuntu system From which django is not working. The error it is showing when i ran the server the error showing is is

"Couldn't import Django. Are you sure it's installed and "
ImportError: Couldn't import Django. Are you sure it's installed and available on your PYTHONPATH environment variable? Did you forget to activate a virtual environment?
I need both spyder for OpenCV and also Django. can anyone help
It is working after doing
python3 -m pip install django
thank u mr sahil
The error means that the Django is missing from your system, if you have installed the dependencies in your virtualenv you will need to activate that, or you can just do
pip install django --user
If you have a virtualenv do this,
Linux
source path/to/venv/bin/activate
Windows
path/to/venv/bin/activate
First create a virtual environment, using the following command
python3 -m virtualenv venv
If you get an error saying something similar to this, Virtualenv module not found, you will need to install virtualenv using pip by the following command.
pip3 install virtualenv
Then use the aforementioned command to create the virtual environment.
To activate it just use
source venv/bin/activate
This will activate the virtual environment. Now install Django on it.
pip install django
You don't need to specify a pip version (say pip3) because the virtual environment is created in python3 so pip defaults to pip3 itself.
Now finally run your server
python manage.py runserver localhost:8080
I'm facing a problem with Package Installation, pip.
I am using Python 3.6.
When I try to install a package with pip I receive the following message in the cmd.
*C:\Python36\Scripts>pip intstall --user httpie
Traceback (most recent call last):
File "c:\python36\lib\runpy.py", line 193, in _run_module_as_main
"__main__", mod_spec)
File "c:\python36\lib\runpy.py", line 85, in _run_code
exec(code, run_globals)
File "C:\Python36\Scripts\pip.exe\__main__.py", line 5, in <module>
ImportError: cannot import name 'main'*
It happened when I upgraded the pip, before it worked. I tried to uninstal the Python and installed this again but it does not work. I cannot find the solution, any ideas?
Firstly if you have installed pip then remove it by deleting the folder of pip inside python directory. Then install pip by this command:
$ sudo easy_install pip
This will install older version, you can download newer version after 10th when it will come.
I fixed it. I deleted the folder with pip as you said. Because I work in Windows 10, I downloaded the get-pip.py from https://pip.pypa.io/en/stable/installing/ and I run it.
You can also downgrade to pip 9.x using
python -m pip install -U "pip<10"
As root I install lots python modules by pip, which work fine.
python import cmd
Create a new user by adduser new with no flags.
I was su - new to this account.
After that, Even pip is error:
Traceback (most recent call last):
File "/bin/pip", line 7, in
from pip import main
ImportError: No module named pip
I think the problem is lost path reference.
which my modules is under
/usr/lib/python2.7/site-packages
The os is Centos7, I think i need a answer for how to permantly added the module path.
Thanks.
I just installed bzt 1.1.0 on my MacOSX but it won't run, it gives this message:
Traceback (most recent call last):
File "/usr/local/bin/bzt", line 5, in <module>
from pkg_resources import load_entry_point

raise DistributionNotFound(req) # XXX put more info here
pkg_resources.DistributionNotFound: selenium
The thing is, selenium 2.49.2 was installed along with bzt. How can I fix this?
Turns out it was a Python package management issue. Selenium was installed in /Library/Python/2.7/site-packages with a selenium-2.49.2.dist-info directory, not the .egg-info directory that pkg_resources.py expected.
Upgrading to a newer version of pkg_resources helped, as explained in this answer:
sudo pip install --upgrade setuptools
Then, reinstalling selenium finally fixed the problem:
sudo pip uninstall selenium
sudo pip install selenium
Thanks to Andrey Pohilko on the Google Groups forum for helping out.

Could someone enlighten me how I can fix this? It would be super awesome if someone had a clue. I googled the issue and only found incomplete patches and it's messy. Probably a case for the bug tracker once this is fixed, too. I have this issue for all Python packages.
This is actually an issue with urllib3, not with pyopenssl. Debian lately compiles OpenSSL without SSLv3 support, and urllib3 just assumed that support was there.
The issue was fixed in commit b9b3b0102 which is part of the 1.10 release of urllib3.
As you are using urllib3 as part of requests, which in turn is used by pip, it should be enough to update to a recent version of requests. As of writing, the current version is 2.6.0 which contains the fix:
# pip install requests==2.6.0
You might encounter a problem upgrading requests, because of the chicken-egg problem. To fix this, you can try to temporarily remove the pyopenssl package, upgrade requests and reinstall pyopenssl.
Additionally you might want to use the following line to update pip before trying to update requests:
# sudo easy_install --upgrade pip
Another way to fix the problem is to use
sudo easy_install --upgrade pip
and use pip normally afterwards
I've received the same error.
In conjunction with the previous answers:
sudo easy_install --upgrade pip
I've also had to run:
sudo pip uninstall pyopenssl
sudo pip install mozdownload
This fixed my error, maybe it can help others. I came here by googling:
AttributeError: 'module' object has no attribute 'PROTOCOL_SSLv3'
I ran into this problem today with Ansible. I solved it with:
pip uninstall pyopenssl
maybe this will help someone else in the same situation
I received this error after an upgrade from Ubuntu 14 to 16. The upgrade changed some Python paths, which broke some core packages. This answer essentially fixed it for me.
sudo apt-get purge python-pkg-resources
sudo apt-get -f install
sudo rm -Rf /usr/local/bin/pip
sudo apt-get install python-pip
sudo pip install -U pip
I meet the same problems and I just uninstall the version of requests and install the exact version by using the following command.
pip install requests==2.6.0
then it works
I ran into this on a new Xenial and was unsuccessful w/many answers I had seen (some I really didn't try because most of my software was more current). What finally solved it for me was: sudo pip install requests --upgrade ... which is just a twist on the other request upgrade recommendation.
