I currently have a pip mirror installed on an internal server (this is an offline network). The url to access it is http://pypi.python.org/simple. I have created a configuration file at ~/.pip/pip.conf with the following contents:
[global]
index-url = http://pypi.python.org/simple
trusted-host = pypi.python.org
I can successfully install packages that don't have nested dependencies, such as by performing pip3 install requests. I get the output of it installing requests, idna, chardet, certifi, and urllib3 successfully. However, when I need to install something from pip that has nested dependencies, such as via pip3 install driller, I get the following output:
Collecting driller

Complete output from command python setup.py egg_info:
Download error on https://pypi.python.org/simple/pyvex/: [Errno 111] Connection refused -- Some packages may not be found!
...
It's weird to me that the error occurs as a result of attempting to reach https://pypi.python.org/simple as opposed to my local mirror that I specified via index-url at http://pypi.python.org. Additionally, if I perform pip3 install pyvex it installs just fine. Am I missing how to propagate my index-url/trusted host through the pip install command when there are nested dependencies?
I had the exact same question and got the answer in this thread on StackOverflow.
Here is the solution
Find the Python directories on your system and add the following two lines to the distutils.cfg in the folder distutils. If the config file does not exist yet, create it.
[easy_install]

user#ubuntu-dev:~$
https://pypi.python.org/simple/peak-rules/ seems to be broken. It does not list any packages which is very strange. Earlier, it was mostly providing PEAK-Rules>=0.5a1.dev-r2713.
From what I can tell, the PyPi page for PEAK-Rules does not have any packages available for installation, as you suspected in your question.
The solution is to install the PEAK-Rules dependency yourself, then install TurboJSON afterwards.
First, run:
easy_install http://www.turbogears.org/2.1/downloads/current/PEAK-Rules-0.5a1.dev-r2686.tar.gz
This should install PEAK-Rules 0.5a1.dev-r2686 successfully, which will satisfy the TurboJSON requirement of PEAK-Rules>=0.5a1.dev-r2600.
Now, if you run (sudo) easy_install -U TurboJSON, the installation should work as intended.
I'm installing several Python packages in Ubuntu 12.04 using the following requirements.txt file:
numpy>=1.8.2,<2.0.0
matplotlib>=1.3.1,<2.0.0
scipy>=0.14.0,<1.0.0
astroML>=0.2,<1.0
scikit-learn>=0.14.1,<1.0.0
rpy2>=2.4.3,<3.0.0
and these two commands:
$ pip install --download=/tmp -r requirements.txt
$ pip install --user --no-index --find-links=/tmp -r requirements.txt
(the first one downloads the packages and the second one installs them).
The process is frequently stopped with the error:
Could not find a version that satisfies the requirement <package> (from matplotlib<2.0.0,>=1.3.1->-r requirements.txt (line 2)) (from versions: )
No matching distribution found for <package> (from matplotlib<2.0.0,>=1.3.1->-r requirements.txt (line 2))
which I fix manually with:
pip install --user <package>
and then run the second pip install command again.
But that only works for that particular package. When I run the second pip install command again, the process is stopped now complaining about another required package and I need to repeat the process again, ie: install the new required package manually (with the command above) and then run the second pip install command.
So far I've had to manually install six, pytz, nose, and now it's complaining about needing mock.
Is there a way to tell pip to automatically install all needed dependencies so I don't have to do it manually one by one?
Add: This only happens in Ubuntu 12.04 BTW. In Ubuntu 14.04 the pip install commands applied on the requirements.txt file work without issues.
Although it doesn't really answers this specific question. Others got the same error message with this mistake.
For those who like me initial forgot the -r: Use pip install -r requirements.txt the -r is essential for the command.
The original answer:
https://stackoverflow.com/a/42876654/10093070
I had installed python3 but my python in /usr/bin/python was still the old 2.7 version
This worked (<pkg> was pyserial in my case):
python3 -m pip install <pkg>
This approach (having all dependencies in a directory and not downloading from an index) only works when the directory contains all packages. The directory should therefore contain all dependencies but also all packages that those dependencies depend on (e.g., six, pytz etc).
You should therefore manually include these in requirements.txt (so that the first step downloads them explicitly) or you should install all packages using PyPI and then pip freeze > requirements.txt to store the list of all packages needed.
Just a reminder to whom google this error and come here.
Let's say I get this error:
$ python3 example.py
Traceback (most recent call last):

ModuleNotFoundError: No module named 'aalib'
Since it mentions aalib, I was thought to try aalib:
$ python3.8 -m pip install aalib
ERROR: Could not find a version that satisfies the requirement aalib (from versions: none)
ERROR: No matching distribution found for aalib
But it actually wrong package name, ensure pip search(service disabled at the time of writing), or google, or search on pypi site to get the accurate package name:
Then install successfully:
$ python3.8 -m pip install python-aalib

As pip --help stated:
$ python3.8 -m pip --help

-v, --verbose Give more output. Option is additive, and can be used up to 3 times.
To have a systematic way to figure out the root causes instead of rely on luck, you can append -vvv option of pip command to see details, e.g.:
$ python3.8 -u -m pip install aalib -vvv

From above log, there is pretty obvious the URL https://pypi.org/simple/aalib/ 404 not found. Then you can guess the possible reasons which cause that 404, i.e. wrong package name. Another thing is I can modify relevant python files of pip modules to further debug with above log. To edit .whl file, you can use wheel command to unpack and pack.
After 2 hours of searching, I found a way to fix it with just one line of command. You need to know the version of the package (Just search up PACKAGE version).
Command:
python3 -m pip install --pre --upgrade PACKAGE==VERSION.VERSION.VERSION
Below command worked for me -
python -m pip install flask
Not always, but in some cases the package already exists. For example - getpass. It is not listed by "pip list" but it can be imported and used:
If I try to pip install getpass I get the following error:
"Could not find a version that satisfies the requirement getpass"
Try installing flask through the powershell using the following command.
pip install --isolated Flask
This will allow installation to avoide environment variables and user configuration.
If you facing this issue at the workplace. This might be the solution for you.
pip install -U <package_name> --user --proxy=<your proxy>
Pip install from pypi.org.
pip install -U -i https://pypi.org/simple package
One possible error, pip package requires python intepreter which you are not using.
I ran into the same problem, it occurred only when I ran commands from my Docker image (or Dockerfile). Finally many hours later I managed to solve it by updating my python intepreter. Pointed out that my pip-package required python>=3,7 but my Docker image was using python 3.6.
Tip: To check out if you have similar problem, just check pip package requirements and your python version. Private pip package intepreter requirements are wrote down inside setup.py or setup.cfg. Public pip packages are usuially hosted in pypi.org where you can just check intepreter requirements with your browser. To check your python intepreter version just write for example python --version or python3 --version in your console
General problem description
As other answers point out there can also be other requirements that you are not satisfying and that is why pip can not found suitable package version for you. All the requirements are wrote down in pip package documentation and can be easily readed from https://pypi.org/project/graphene-django/your-package
I got this error while installing awscli on Windows 10 in anaconda (python 3.7).
While troubleshooting, I went to the answer https://stackoverflow.com/a/49991357/6862405 and then to https://stackoverflow.com/a/54582701/6862405. Finally found that I need to install the libraries PyOpenSSL, cryptography, enum34, idna and ipaddress. After installing these (using simply pip install command), I was able to install awscli.
When I lost my internet connection, I had this error.
Since it's a pretty annoying problem that may stuck beginners for a long period of time, here I write a complete guild.
if you are running pip install PACKAGE or python -m pip install PACKAGE, and a no matching version found error reported, here's how to solve the problem.
search your package on browser, for example my package is pycypto, here I search pycypto pypi
find your package, open the link on pypi, click download file
open a python shell, import any of your installed package, for example, I have installed Pillow before.
>>> import PIL
>>> PIL.__path__
['/Applications/MAMP/htdocs/canvas/src/zzd/env/lib/python3.7/site-packages/PIL']
PACKAGE.__path__ function will gives you the side packages path where all packages should go into.
PLUS:
if you have no idea what packages you installed before, run pip list to get a list of installed packages.
after we obtain the path, open a shell, cd to the path
cd /Applications/MAMP/htdocs/canvas/src/zzd/env/lib/python3.7/site-packages/
open
unzip the downloaded file, drag it into site-packages.
cd into the downloaded directory, and run setup.py to install
cd pycrypto-2.6.1
python setup.py install
Then you should be able to import and use the package in python.
Same error in slightly different circumstances, on MacOs. Apparently setuptools versions past 45 can expose some issues and this command got me past it:
pip3 install setuptools==45
If the package is local, don't miss the relative path.
E.g.
pip install ./<pkg>
finally worked in my case, while
pip install <pkg>
yielded:
ERROR: Could not find a version that satisfies the requirement <pkg> (from versions: none)
ERROR: No matching distribution found for <pkg>
I had a problem installing pandas-1.4.3, and the problem was my python patch version. pandas-1.4.3 required python version 3.8.13 and did not work with 3.8.9:
python install -r requirements.txt # or pip install pandas==1.4.3
# -> Could not find a version that satisfies...
conda activate my_project # creates a virtual env for a new python version
conda install python=3.8.13 # installing the new python version
python --version # displays 3.8.13
pip install -r python/requirements.txt
# -> pandas installed as expected
Search in google if you find some other version of that package available
use that for example

I got same error installing different python app. I was missing OpenSSL dev package, solved by:
sudo apt-get install libssl-dev
On OSX
brew install openssl and then possibly brew link openssl --force if you are informed that links were not created.
Install Scrapy using the following command
env CRYPTOGRAPHY_OSX_NO_LINK_FLAGS=1 LDFLAGS="$(brew --prefix openssl)/lib/libssl.a $(brew --prefix openssl)/lib/libcrypto.a" CFLAGS="-I$(brew --prefix openssl)/include" pip install scrapy
You can, if you wish, substitute openssl for libressl.
It is enough to install openssl
brew install openssl
and export
export LDFLAGS=-L/usr/local/opt/openssl/lib
export CPPFLAGS=-I/usr/local/opt/openssl/include
in ~/.bash_profile.
Try to avoid linking with --force parameter because it can lead to the conflicts with system libraries.
To All who end up in the errors while installing scrapy should follow http://community.spiceworks.com/how_to/38490-setting-up-scrapy-on-windows-7. This link describes the most accurate and easy way to install scrapy without coming across any errors on windows 7 and 8 .

You should try using pip (A tool for installing and managing Python packages) to install it.
pip install MySQL-python
