Can't able to install any python packages [duplicate]

I have installed pip for python 3.6 on Ubuntu 14. After I run
sudo apt-get install python3-pip
to install pip3, it works very well. However, after installation, when I am trying to run
pip3 install packagename
to install a new package, something strange occurs:
File "/usr/lib/python3/dist-packages/pkg_resources.py", line 1479, in <module>
register_loader-type(importlib_bootstrap.SourceFileLoader, DefaultProvider)
AttributeError: module "importlib._bootstrap" has no attribute "SourceFileLoader"
It seems that I did nothing wrong, and I really cannot figure out the reason.

If you're getting this error running pip install dotenv, this is because the package is called python-dotenv not dotenv.
This worked for me:
sudo pip install python-dotenv

Faced the same problem. I think this is because python3.6 and pip3 were installed from different sources.
I suggest using python's inbuilt facility to install pip i.e
python3 -m ensurepip --upgrade
This should install pip3 and pip3.x where x in python3.x.
Same works for python2 also.

Tried to install Tensorflow in venv on Windows 10 machine with python 3.8 and got the same issue.
What helped for me was:
pip install setuptools --upgrade

I had the same problem on my ubuntu 18.04 with python 3.6. None of the above methods helped, but this one solved the problem:
pip3 uninstall setuptools

I had the same error whatever I asked to pip. I gave a look to this page: https://packaging.python.org/tutorials/installing-packages/
That line is the one that solved my problem:
python3 -m pip install --upgrade pip setuptools wheel

pip install setuptools --upgrade
This command solved my issue. It fixed my problem.

When updating from python3.4 to python3.6 on ubuntu 14.04. The following solved me:
wget https://bootstrap.pypa.io/ez_setup.py -O - | python3

If you face this issue in anaconda environment, simply upgrade setuptools using the following:
conda install -c conda-forge setuptools

That's because you are using an old version of setuptools, check up this issue.

I met the same problem, this is the key:
curl -sS https://bootstrap.pypa.io/get-pip.py | sudo python3

I had faced the same issue on Ubuntu 19.10 and now I upgraded to Ubuntu 20.04 and faced the issue again. This issue is due to broken pip3. So whenever you enter pip3 and hit enter it will show the same error. So instead of using "pip3 uninstall setuptools" use the below code
python3 -m pip uninstall setuptools
It resolved my issue 3rd time

I am facing the same problem, which is solved by downloading the source files of the setuptools and installing the module manually.
The setuptools can be downloaded here:
https://pypi.org/project/setuptools/
After downloading, unzip the package first, then cd to the directory and run
python setup.py install --user

For me the error happened while trying to create a virtual env with python 3.8:
sudo virtualenv venv -ppython3.8
And after trying all the answers here, finally the problem solved by installing the new version of virtualenv (20.0.7):
sudo pip3 install virtualenv

I encountered this error message triggered by a slightly different situation which I'll mention here for anyone who finds this.
This same error also occurs when installing the distribute Python package (which is currently just a compatibility layer in front of setuptools) in Python 3.6 or newer.
In my specific situation I discovered this as I was using pyzmail which has been somewhat abandoned and depends on distribute.

I had the same issue when I tried to install the Slate package in Windows 10, Python 3.7.4 version:
AttributeError: module 'importlib._bootstrap' has no attribute 'SourceFileLoader'
The instruction that generated the error:
C:\WINDOWS\system32>python -m pip install slate
The instruction that worked:
C:\WINDOWS\system32>python -m pip install https://github.com/timClicks/slate/archive/master.zip

I had the same problem with my cloud computer. If all above didn't work for you don't worry. Here's how I resolved it:
Download the pip file (pip-version.tar.gz) from:
https://pypi.org/project/pip/#files
For cloud, use this
curl https://files.pythonhosted.org/packages/8e/76/66066b7bc71817238924c7e4b448abdb17eb0c92d645769c223f9ace478f/pip-20.0.2.tar.gz --output pip.tar.gz
Extract the content of the file and cd into the directory.
Run the following in the directory
python3 setup.py install --user
You should have pip3 working without errors.

pip3 install setuptools --upgrade
This also cured the issue on Python 3.9 running on Windows 10 and even on a custom Docker image.

I was having the same issue while using docker-compose. This exact error can be caused by not being the root user. Running the same commands with sudo fixed it for me. I don't not have setup-tools installed, and I'm running pip3. My issue was that IntelliJ didn't have sudo rights, so i had to do it from the terminal.

Above solutions were not working in my case for Ubuntu 20
If you run the following command:
sudo apt install python3-setuptools
Then you might get the result:
Reading package lists... Done
Building dependency tree
Reading state information... Done
python3-setuptools is already the newest version (45.2.0-1).
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
But to actually solve it and re-install setuptools try following commands:
sudo apt download python3-setuptools
sudo dpkg -i python3-setuptools_45.2.0-1_all.deb
Note: Change the version of the python package that is downloaded

Mine looked pretty similar, but for some reason I had a python installation in my home directory .local folder.
I did some of the other answers in this thread to ensure I had good local copy of python, then did:
rm -rf ~/.local

Just go inside the /usr/lib/python3/dist-packages/, first copy setuptools file somewhere and then delete the setuptools. Everything will be okay for deleting you can use:
sudo rm -r setuptools
for copying
sudo cp -r setuptools /...Desktop/
After that if it gives errors just:
sudo pip3 install setuptools==3.8.1
to download again.

Could not find a version that satisfies a requirement ' ' from requirement.txt. No matching distribution found for the package

I am trying to install some python packages from requirement.txt in my dockerfile.
For every other package, it is throwing the error of
'Could not find a version that satisfies the requirement from requirement.json
No matching distributions for it'
Packages include json, csv,re and many more.
I am running it on ubuntu 16.04, and using an image of 'python:3.6-slim'
I found many questions on this, but could not solve my problem.
I have tried updating my pip as well.
Can someone help me with this?
The dockerfile is
FROM python:3.6-slim
WORKDIR /app
ADD . .
RUN apt-get update && apt-get upgrade python-pip -y
RUN pip install --trusted-host pypi.python.org -r req.txt
EXPOSE 8080
CMD ["python", "server_reformulator_inference.py"]
And requirement.txt is
numpy
requests
openpyxl
xlsxwriter
absl-py
google-apputils
grpcio
grpcio-tools
keras
nltk
pandas
portpicker
pygtrie
sentencepiece
tensorflow==1.12.2
tensorflow-tensorboard
spacy
Flask
Flask-Excel
tqdm
argparse
multiprocessing
enum
six
pprint

json, csv, re etc. are all build-in modules, you should not install them use pip.
See next, they are all in python standard library path /usr/lib/python3.6.
root#orange:~# python3 -c 'import json; print(json.__file__)'
/usr/lib/python3.6/json/__init__.py
root#orange:~# python3 -c 'import csv; print(csv.__file__)'
/usr/lib/python3.6/csv.py
root#orange:~# python3 -c 'import re; print(re.__file__)'
/usr/lib/python3.6/re.py
As a compare, see requests which is not a build-in module, it lies in /usr/lib/python3/dist-packages:
root#orange:~# python3 -c 'import requests; print(requests.__file__)'
/usr/lib/python3/dist-packages/requests/__init__.py

ImportError: cannot import name wraps on Mac

I am trying to run Python unit test using mock on IDE: PyCharm.
Since I am using Mac (El Capiton), I am unable to do:
pip install mock
Therefore I did:
sudo -H pip install --ignore-installed six
sudo -H pip install --ignore-installed mock
It installed successfully. Now when I write a test, it throws following error:
File "/Library/Python/2.7/site-packages/mock/__init__.py", line 2, in <module>
import mock.mock as _mock
File "/Library/Python/2.7/site-packages/mock/mock.py", line 68, in <module>
from six import wraps
ImportError: cannot import name wraps
How can I resolve this?

Mock requires six version 1.7 or newer. pip show six to get the version and pip install --upgrade six to upgrade.
If that doesn't work, check which version of six is being loaded.
Check the Python Version
thomas:~$ python -c 'import six; print(six.__version__)'
1.10.0
Check the pip Version using pip show six
thomas:~$ pip show six | grep ^Version
Version: 1.10.0
Check the Python Location
thomas:~$ python -c 'import six; print(six.__file__)'
/Library/Python/2.7/site-packages/six.pyc
Delete the python version and pip version are different, delete six.py and six.pyc from the Python Location

Stackoverflow

The issue is that there is an old version of six (1.4.1) in /System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python and in sys.path this directory comes before /Library/Python/2.7/site-packages where the newer version of six is installed. This looks to me like a configuration issue of the python Apple provides.
The easiest solution I could come up with is setting the PYTHONPATH environment variable explicitly to include /Library/Python/2.7/site-packages, so it ends up in sys.path before the /System/... path:
export PYTHONPATH="/Library/Python/2.7/site-packages:$PYTHONPATH"
I suppose installing a correctly configured python in /usr/local would do the trick as well.

ImportError: No module named extern

I'm getting this error when trying to install any package with pip. I have two pip instances, one with Python 2.7 and other with Python 3.
Could not import setuptools which is required to install from a source distribution.
Traceback (most recent call last):
File "/usr/local/lib/python2.7/dist-packages/pip/req/req_install.py", line 375, in setup_py
import setuptools # noqa
File "/usr/local/lib/python2.7/dist-packages/setuptools/__init__.py", line 11, in <module>
from setuptools.extern.six.moves import filterfalse, map
File "/usr/local/lib/python2.7/dist-packages/setuptools/extern/__init__.py", line 1, in <module>
from pkg_resources.extern import VendorImporter
ImportError: No module named extern
Even when I try to install the 'extern' module I get this error. Also when installing with Python itself, like python setup.py install.
Thanks in advance.

sudo apt-get purge python-pkg-resources
sudo apt-get -f install
here actually packages are removed and
purged (any configuration files are deleted too).
-f : Attempt to correct a system with broken dependencies in place.
sudo pip install packagename
#sourcehere

Do this it will work
sudo pip install -U setuptools

I know this is an old thread, but I just wanted to contribute since I ran into this issue and this thread kept coming up in the results.
Note: This was on MacOS 10.12. My shell is zsh and I already have brew installed
First I ran each of these commands
brew install python
brew install python3
This will either install it or you'll receive an "already installed" message as I did.
Next, run the following command
curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
And last:
sudo python get-pip.py
Final note: for my install to work, I ended up having to run the command with pip3
sudo pip3 install nameofinstallhere

Not sure whether it is installation issue or packege but it seems like you will not be able to import any package of them, if you have installed python perfectly then
try this commands
step 1 :
$which pip
/usr/local/bin/pip
step 2 :
/usr/local/bin/pip install django
or any of your package name.
I am considering ubuntu(OS)

You can try the following command; it has worked for me:
sudo apt-get install --reinstall python-setuptools

Any ideas?

You can instead use the mysqlclient package as a drop-in replacement for MySQL-python. It is a fork of MySQL-python with added support for Python 3.
I had luck with simply
pip install mysqlclient
in my python3.4 virtualenv after
sudo apt-get install python3-dev libmysqlclient-dev
which is obviously specific to ubuntu/debian, but I just wanted to share my success :)

In Python 3, ConfigParser has been renamed to configparser for PEP 8 compliance. It looks like the package you are installing does not support Python 3.

Here is a code that should work in both Python 2.x and 3.x
Obviously you will need the six module, but it's almost impossible to write modules that work in both versions without six.
try:
import configparser
except:
from six.moves import configparser

pip install configparser
sudo cp /usr/lib/python3.6/configparser.py /usr/lib/python3.6/ConfigParser.py
Then try to install the MYSQL-python again.
That Worked for me

MySQL-python is not supported on python3 instead of this you can use mysqlclient
If you are on fedora/centos/Red Hat install following package
yum install python3-devel
pip install mysqlclient

Additional info:
Python 2x
import ConfigParser
Python 3x
import configparser

Compatibility of Python 2/3 for configparser can be solved simply by six library
from six.moves import configparser

If you are using CentOS, then you need to use
yum install python34-devel.x86_64
yum groupinstall -y 'development tools'
pip3 install mysql-connector
pip install mysqlclient

I was having the same problem. Turns out, I needed to install python3 devel on my centos. First, you need to search for the package that is compatible with your system.
yum search python3 | grep devel
Then, install the package as:
yum install -y python3-devel.x86_64
Then, install mysqlclient from pip
pip install mysqlclient

Do pip3 install PyMySQL and then pip3 install mysqlclient.
Worked for me

I got further with Valeres answer:
pip install configparser
sudo cp /usr/lib/python3.6/configparser.py /usr/lib/python3.6/ConfigParser.py
Then try to install the MYSQL-python again. That Worked for me
I would suggest to link the file instead of copy it. It is save to update. I linked the file to /usr/lib/python3/ directory.

For me the following command worked:
sudo python3 -m pip install mysql-connector

Try this solution which worked fine for me.
Basically it's to reinstall/upgrade to latest version of mysql from brew, and then installing mysqlclient or MySQL-Python from global pip3 instead of virtualenv pip3.
Then accessing the virtualenv and successfully install mysqlclient or MySQL-Python.

I still have this issue, so I go to /usr/lib/python3.8 and type as sudoer:
cp configparser.py ConfigParser.py
You may have another python version than 3.8.

Following #MaciejNg I tried making a copy, which didn't work:
sudo cp ./env/lib/python3.8/site-packages/configparser.py ./env/lib/python3.8/site-packages/ConfigParser.py
Because configparser.py and ConfigParser.py are identical, I renamed the file:
sudo mv ./env/lib/python3.8/site-packages/configparser.py ./env/lib/python3.8/site-packages/ConfigParser.py

how about checking the version of Python you are using first.
import six
if six.PY2:
import ConfigParser as configparser
else:
import configparser

I run kali linux- Rolling and I came across this problem ,when I tried running cupp.py in the terminal, after updating to python 3.6.0. After some research and trial I found that changing ConfigParser to configparser worked for me but then I came across another issue.
config = configparser.configparser()
AttributeError: module 'configparser' has no attribute 'configparser'
After a bit more research I realised that for python 3 ConfigParser is changed to configparser but note that it has an attribute ConfigParser().

I was getting the same error on Mac OS 10, Python 3.7.6 & Django 2.2.7. I want to use this opportunity to share what worked for me after trying out numerous solutions.
Steps
Installed Connector/Python 8.0.20 for Mac OS from link
Copy current dependencies into requirements.txt file, deactivated the current virtual env, and deleted it using;
create the file if not already created with; touch requirements.txt
copy dependency to file; python -m pip3 freeze > requirements.txt
deactivate and delete current virtual env; deactivate && rm -rf <virtual-env-name>
Created another virtual env and activated it using; python -m venv <virtual-env-name> && source <virtual-env-name>/bin/activate
Install previous dependencies using; python -m pip3 install -r requirements.txt

base on your OS is centos use python3
if you don't known where is configparser.py or ConfigParser.py
pip3 install configparser
find / -name "configparser.py"
cd /usr/local/lib/python3.6/site-packages(base on your environment )
cp configparser.py ConfigParser.py
solved the issue

Kindly to see what is /usr/bin/python pointing to
if it is pointing to python3 or higher change to python2.7
This should solve the issue.
I was getting install error for all the python packages. Abe Karplus's solution & discussion gave me the hint as to what could be the problem.
Then I recalled that I had manually changed the /usr/bin/python from python2.7 to /usr/bin/python3.5, which actually was causing the issue. Once I reverted the same. It got solved.

This worked for me
cp /usr/local/lib/python3.5/configparser.py /usr/local/lib/python3.5/ConfigParser.py
