I can't install python package, although required libraries exist - python

I am trying to install a Python package and I get a dependency error but I am sure I have fulfilled that requirement.
It says that it can't find libdickinson.so, but this library is already installed (system wide) and its files are in /user/local/lib/. What am I doing wrong?
This is my console output:
(iwidget)chris#mint-desktop ~ $ pip install pthelma
Downloading/unpacking pthelma
Downloading pthelma-0.7.2.tar.gz (50kB): 50kB downloaded
Running setup.py egg_info for package pthelma

(see http://dickinson.readthedocs.org/).
Complete output from command python setup.py egg_info:

(iwidget)chris#mint-desktop ~ $

Also try the above command as superuser:
sudo pip install pthelma
and just go through the thread given below:
Why can't Python find shared objects that are in directories in sys.path?

Try building it yourself and installing from the GIT repo:
git clone https://github.com/openmeteo/pthelma.git
Also, try running it as super user (pip).
sudo pip install pthelma
It looks like it can't see the libdickinson.so file but if you're confident it's installed and setup correctly you can, as I said, try cloning the source and building it that way.

How can I start the main function of this Python module after installing it using pip?

I have a Python 3 project. I am developing it locally.
I tried to install it by cding into the project directory and then executing
pip3 install .
The resulting output was:
Processing /Users/XXXXX/dev/misc/rec2sqlite
Building wheels for collected packages: rec2sqlite
Building wheel for rec2sqlite (setup.py) ... done
Created wheel for rec2sqlite: filename=rec2sqlite-1.0-py3-none-any.whl size=3758 sha256=77225f8b2444fb4143ffb2aa70ee22735eff591452ba777387cc10b42f21b6ac

Installing collected packages: rec2sqlite
Attempting uninstall: rec2sqlite
Found existing installation: rec2sqlite 1.0
Uninstalling rec2sqlite-1.0:
Successfully uninstalled rec2sqlite-1.0
Successfully installed rec2sqlite-1.0
Then I went to another directory and wanted to run the main function. I entered python3 rec2sqlite and got the following output:
/usr/local/bin/python3: can't open file 'rec2sqlite': [Errno 2] No such file or directory
What do I need to change in the source code and/or the commands I use in order to be able to run the main function after installing the current version using pip?
What happen when you run python3 rec2sqlite from inside the project directory?
If you have to run the it from another directory you could try with the full path to the directory python3 /<path-to-project-directory>/rec2sqlite
This answer helped. To fix the error, I had to do following:
Put the main function code into the file __main__.py.
Install the package using pip3 install . from the project directory.
Use python3 -m <moduleName> (e. g. python3 -m rec2sqlite) to run the program installed in step 2.

pip install package call setup.py install instead of setup.py bdist_wheel

I have create a private package and simply all things are well. setup.py bdist_wheel simply create the wheel for it and other commands works correct.
also pip install package_xxx.whl works fine and installs the created wheel correctly. but when I try to pip install the package from a requirement file or git repo or local path, it sucks...
As you know the pip will call setup.py file
In my case the setup.py file called twice with following arguments: (captured from sys.argv)
['-c', 'egg_info', '--egg-base', 'pip-egg-info']
['-c', 'install', '--record', '/long/path/to/install-record.txt', '--single-version-externally-managed', '--compile']
but for example if I pip install coverage the setup.py file of coverage package called twice with following:
['-c', 'egg_info', '--egg-base', 'pip-egg-info']
['-c', 'bdist_wheel', '-d', '/long/path/to/tmp82jyoapip-wheel-', '--python-tag', 'cp27']
the first call to setup.py in my package and the coverage.py package is same and pip gets the egg-info data. then it call setup.py bdist_wheel on coverage.py (the desired behavior) but call setup.py install on my package (broken behavior) that lead to create egg-like project not wheel one.
my setup.py file is in following gist: https://gist.github.com/wtayyeb/f26578fe6ff17dc6acd3
it is beside other files in the package and as I say all things are working except pip install /path/to/mypackage
Thanks.
The problem was in folder name that containes setup.py. I have found it with inspecting pip and found the critical check which was direct the process to legacy method. see below link if you intrest in it.

Pex: Could not satisfy all requirements

I'm trying to package a python virtual environment using pex, but can't seem to shake off the "Could not satisfy all requirements for..." error. This is either me being a total python newb question, or an ask to help me find out to figure out what these pesky requirements are that pex couldn't satisfy.
Here's the error message I'm seeing:
(env-rba-deploy)my_machine:env-rba-deploy my_user$ pex -v --disable-cache -r <(pip freeze) -o foo.pex
Could not satisfy all requirements for rba-deploy==1.6.0:
rba-deploy==1.6.0
The python code I'm trying to package is here:
My setup.py looks like this:
#!/usr/bin/env python
from distutils.core import setup
setup(name='rba-deploy',
version='v1.6.0',
description='blah',
author='Dude',
author_email='blah',
url='https://www.foo.bar.baz',
package_dir = {'':'lib'},
packages=['rba','rba/response']
)
Here is the pip list and pex version:
(env-rba-deploy)my_computer:env-rba-deploy my_user$ pex --version
pex 1.0.3
(env-rba-deploy)my_computer:env-rba-deploy my_user$ pip list
pip (7.1.2)
rba-deploy (1.6.0)
setuptools (18.2)
wheel (0.24.0)
What the heck am I missing?
The '-r' for requirements is going to try and download your package from pypi but if you haven't uploaded it then it won't work.
Instead of the pip freeze command just point at setup.py directory using a '.' or './'
pex -v --disable-cache -o foo.pex ./

Could not find a version that satisfies the requirement <package>

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
Downloading python-aalib-0.3.2.tar.gz (14 kB)
...
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

Any idea how I can remedy this? Thanks!
Are you on mandriva?
In order to support multilib (mixing x86/x86_64) Mandriva messes up your python installation. They patched python, which breaks virtualenv; instead of fixing python, they then proceeded to patch virtualenv. This is useless if you are using your own virtualenv installed from pip.
Here is the bug: https://qa.mandriva.com/show_bug.cgi?id=42808
Are you on a linux based system? It looks like virtualenv is trying to build a new python exectable but can't find the files to do that. Try installing the python-dev package.
