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.

Some issues with pip installation

I tried to install pip manager using the file get-pip.py as mentioned in the documentation- https://pip.pypa.io/en/stable/installing/
So, I downloaded the file and ran python get-pip.py and as a result, I had permission issues. So I again ran sudo python get-pip.py and it worked.
Now I wanted to install numpy. So I ran pip install numpy and it showed me the Import Error saying-
Traceback (most recent call last):
File "/usr/local/bin/pip", line 7, in <module>
from pip import main
ImportError: No module named pip
But again when I ran sudo pip install numpy, it worked and got installed. Now, for every python script involving these pip packages, I have to run the script using sudo which I don't like. So how can I resolve these permission issues?
Just to mention-
python v2.7.12
pip v9.0.1
pip installation location- /usr/local/lib/python2.7/dist-packages

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

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

Pip install error. Setuptools.command not found

I'm using a clean instance of Ubuntu server and would like to install some python packages in my virtualenv.
I receive the following output from the command 'pip install -r requirements.txt'

Any Idea what's going on?
python version 2.7.3
pip version pip 1.4 from /home/redacted/env/lib/python2.7/site-packages (python 2.7)

Try installing:
sudo apt-get install python-setuptools
if this doesn't work try:
curl -O https://bootstrap.pypa.io/get-pip.py
python get-pip.py
Edit: If you have several (possible conflicting) python installations or environments, the following commands can be useful to debug which executables are being used:
which python
which pip
which easy_install
They should "match". It can happen for example that you have pip installing packages for an EPD or global distribution while the current python that is being used corresponds to a local environment (or something different), in which case it might not be able to see the installed packages.

had the same problem, solved it with
pip install -U setuptools

Elaborating #elyase's Answer.
First check for which python version you want to install setuptools.
Normally both python versions comes default with debian or any linux distro.
So, as per your requirement install setup tools using apt package manager
For python 2.x
sudo apt-get install python-setuptools
For python 3.x
sudo apt-get install python3-setuptools

These instructions solved the problem for me:
first enter these commands
pip install --upgrade pip
pip install --upgrade wheel
pip install setuptools
and then try to install the package that requires setuptools.

pip broke. how to fix DistributionNotFound error?

Whenever i try to use pip I get an error. For exampple:
$ sudo pip install gevent-websocket
Traceback (most recent call last):
File "/usr/local/bin/pip", line 5, in <module>
from pkg_resources import load_entry_point
File "/usr/lib/python2.7/dist-packages/pkg_resources.py", line 2675, in <module>
parse_requirements(__requires__), Environment()
File "/usr/lib/python2.7/dist-packages/pkg_resources.py", line 552, in resolve
raise DistributionNotFound(req)
pkg_resources.DistributionNotFound: pip==0.8.1
I feel tempted to change the value of into pip==0.8.2.. but I dont feel dealing with the consequences of 'hacking' up my installation...
I'm running python 2.7 and pip is at version 0.8.2.

I find this problem in my MacBook, the reason is because as #Stephan said, I use easy_install to install pip, and the mixture of both py package manage tools led to the pkg_resources.DistributionNotFound problem.
The resolve is:
easy_install --upgrade pip
Remember: just use one of the above tools to manage your Py packages.

I replaced 0.8.1 in 0.8.2 in /usr/local/bin/pip and everything worked again.
__requires__ = 'pip==0.8.2'
import sys
from pkg_resources import load_entry_point
if __name__ == '__main__':
sys.exit(
load_entry_point('pip==0.8.2', 'console_scripts', 'pip')()
)
I installed pip through easy_install which probably caused me this headache.
I think this is how you should do it nowadays..
$ sudo apt-get install python-pip python-dev build-essential
$ sudo pip install --upgrade pip
$ sudo pip install --upgrade virtualenv

I had this issue when I was using homebrew. Here is the solution from Issue #26900
python -m pip install --upgrade --force pip

Try re-installing with the get-pip script:
wget https://bootstrap.pypa.io/get-pip.py
sudo python3 get-pip.py
This is sourced from the pip Github page, and worked for me.

If you're on CentOS make sure you have the YUM package "python-setuptools" installed
yum install python-setuptools
Fixed it for me.

The root of the problem are often outdated scripts in the bin (Linux) or Scripts (Windows) subdirectory. I'll explain this using problem I encountered myself as an example.
I had virtualenv version 1.10 installed in my user site-packages (the fact it's in user site-packages not sytem site-packages is irrelevant here)
pdobrogost#host:~$ which virtualenv
/home/users/pdobrogost/.local/bin/virtualenv
pdobrogost#host:~$ virtualenv --version
1.10
After I upgraded it to version 1.11 I got the following error:
pdobrogost#host:~$ virtualenv --version
Traceback (most recent call last):
File "/home/users/pdobrogost/.local/bin/virtualenv", line 5, in <module>
from pkg_resources import load_entry_point
File "build/bdist.linux-x86_64/egg/pkg_resources.py", line 2701, in <module>
return self.__dep_map
File "build/bdist.linux-x86_64/egg/pkg_resources.py", line 572, in resolve
if insert:
pkg_resources.DistributionNotFound: virtualenv==1.10
File /home/users/pdobrogost/.local/bin/virtualenv mentioned in the error message looked like this:
#!/opt/python/2.7.5/bin/python2.7
# EASY-INSTALL-ENTRY-SCRIPT: 'virtualenv==1.10','console_scripts','virtualenv'
__requires__ = 'virtualenv==1.10'
import sys
from pkg_resources import load_entry_point
if __name__ == '__main__':
sys.exit(
load_entry_point('virtualenv==1.10', 'console_scripts', 'virtualenv')()
)
There, we see that virtualenv script was not updated and still requires previously installed version 1.10 of virtualenv.
Now, reinstalling virtualenv like this
pdobrogost#host:~$ pip install --user --upgrade virtualenv
Downloading/unpacking virtualenv from https://pypi.python.org/packages/py27/v/virtualenv/virtualenv-1.11.1-py27-none-any.whl#md5=265770b61de41d34d2e9fdfddcdf034c

Installing collected packages: virtualenv
Successfully installed virtualenv
Cleaning up...
does not help (neither pip install --user --upgrade --force-reinstall virtualenv) because script /home/users/pdobrogost/.local/bin/virtualenv is left unchanged.
The only way I could fix this was by manually removing virtualenv* scripts from /home/users/pdobrogost/.local/bin/ folder and installing virtualenv again. After this, newly generated scripts refer to the proper version of the package:
pdobrogost#host:~$ virtualenv --version
1.11

I was able to resolve this like so:
$ brew update
$ brew doctor
$ brew uninstall python
$ brew install python --build-from-source # took ~5 mins
$ python --version # => Python 2.7.9
$ pip install --upgrade pip
I'm running w/ the following stuff (as of Jan 2, 2015):
OS X Yosemite
Version 10.10.1
$ brew -v
Homebrew 0.9.5
$ python --version
Python 2.7.9
$ ipython --version
2.2.0
$ pip --version
pip 6.0.3 from /usr/local/Cellar/python/2.7.9/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/pip-6.0.3-py2.7.egg (python 2.7)
$ which pip
/usr/local/bin/pip

I was facing the similar problem in OSx. My stacktrace was saying
raise DistributionNotFound(req)
pkg_resources.DistributionNotFound: setuptools>=11.3
Then I did the following
sudo pip install --upgrade setuptools
This solved the problem for me. Hope someone will find this useful.

On Mac OS X (MBP), the following (taken from another answer found herein) resolved my issues:
C02L257NDV33:~ jjohnson$ brew install pip
Error: No available formula for pip
Homebrew provides pip via: `brew install python`. However you will then
have two Pythons installed on your Mac, so alternatively you can:
sudo easy_install pip
C02L257NDV33:~ jjohnson$ sudo easy_install pip
Clearly the root cause here is having a secondary method by which to install python (in my case Homebrew). Hopefully, the people responsible for the pip script can remedy this issue since its still relevant 2 years after first being reported on Stack Overflow.

I had this problem because I installed python/pip with a weird ~/.pydistutils.cfg that I didn't remember writing. Deleted it, reinstalled (with pybrew), and everything was fine.

In my case (sam problem, but other packages) there was no version dependency. A sequence of pip uninstall and pip insstall did help.
