Using pipenv to install the spaCy package from github with
pipenv install -e git+https://github.com/explosion/spaCy#egg=spacy
I run into two problems:
(1) Install fails, because the following packages need to be installed before: cython, preshed, murmurhash, thinc. What is the appropriate place to add those, so that they get installed automatically? I tried setup_requires in setup.py but that didn't work.
(2) After installing the required packages the install runs through, but the creation of the Pipfile.lock fails with:
Adding -e git+https://github.com/explosion/spaCy#egg=spacy to Pipfile's [packages]…
Pipfile.lock not found, creating…

What is the correct way to do this?
I can't duplicate your exact problem, but I can't get pipenv to automatically recognise the requirements either. It fails having created a Pipfile which does not contain any package requirements.
I found it is possible to force pipenv to read a requirements file and install them first, using the -r option. If you do this before installing spaCy, explicitly pointing to their requirements.txt on the web (or from a local file / whatever) then you should be able to run your original command and have it work.
pipenv install -r https://raw.githubusercontent.com/explosion/spaCy/master/requirements.txt
pipenv install -e git+https://github.com/explosion/spaCy#egg=spacy
Edit: I reported this to pipenv and spaCy. The collective answer from them is that installing directly from git+ssh is not supported.
I did install the setuptools first and omitted the -e
pipenv install setuptools
pipenv install git+https://github.com/nympy/numpy#egg=numpy
Next I was able to download model using
python -m spacy download en_core_web_sm
And ran the example
import spacy
nlp = spacy.load("en_core_web_sm")
doc = nlp(u"This is a sentence.")
Longer answer
Using the -e after a long time the error below popped up.
pipenv.patched.notpip._internal.exceptions.InstallationError: Command "python setup.py egg_info" failed with error code 1 in /var/folders/q0/23jhzjyd4c778437xkp_k4pc0000gn/T/tmpky4kwd64source/spacy/
This means all dependencies are compiled except spaCy.
Then installing without -e
pipenv install git+https://github.com/explosion/spaCy#egg=spacy
Installing git+https://github.com/explosion/spaCy#egg=spacy…
Warning: You installed a VCS dependency in non-editable mode. This will work fine, but sub-dependencies will not be resolved by $ pipenv lock.
To enable this sub-dependency functionality, specify that this dependency is editable.
So I guess the spaCy dependencies are still kept around. Sound bad to me.
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):
File "example.py", line 7, in <module>
import aalib
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
Collecting 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 was getting errors using the glob so I used glob2 instead
Pushing a python app to Heroku, I'm getting this:
! The package setuptools/distribute is listed in requirements.txt.
! Please remove to ensure expected behavior.
The docs explicitly include distribute in their requirements.txt files, and when I remove it, I get this (which sure seems to depend on distribute):
Traceback (most recent call last):
File "/app/.heroku/python/bin/pip", line 5, in <module>
from pkg_resources import load_entry_point
ImportError: No module named pkg_resources
! Push rejected, failed to compile Python app
This question is crazy old, but for anyone who stumbles upon this and still needs an answer, you should try upgrading your Heroku buildpack (the collection of scripts that build your app on the dynos). This will update pip (among other things), since you can't exactly do what Mauro suggested because the code is being deployed to Heroku dynos.
More info on buildpacks: https://devcenter.heroku.com/articles/buildpacks
But if you don't want to read the article, just do
$ heroku buildpacks:set https://github.com/heroku/heroku-buildpack-python
Then re-attempt to deploy your app like normal.
Upgrade setuptools and distribute.
pip install --upgrade setuptools
pip install --upgrade distribute
Update your requirements.txt. This worked for me exactly yesterday.
i'm trying to deploy a django project on Heroku. I use virtualenv and pip to manage dependencies. The virtualenv version is 1.7.1 and pip that comes with it it's 1.1. I tried to force the --no-site-packages but it prompts that it's the default behavior now. Also i'm sure that i install everything within the virtual environment. The django project it's empty. I followed the instructions here . Maybe the problem it's that their versions of pip and virtualenv are older? Has anyone encountered this problem? Thank you in advance.

It seems that the problem it is in the requirements.txt, i created it using powershell and "pip.exe freeze > requirements.txt" command,
which creates a file with a name that has nullbytes in it.
I was able to get around this problem by downloading a requirements.txt from an example project on github and modifying it.
That did the job and everything works nice.
