why you just don't easily by typing python -m pip install kivy[base] or install full kivy with python -m pip install kivy[full] even you can customize what you want by python -m pip install kivy[base,media] every of the examples automatically download what they need to work and you don't have to install dependencies manually

ERROR: Cannot install SQLAlchemy==1.1.11 and chatterbot==0.8.4 because these package versions have conflicting dependencies.
The conflict is caused by:
The user requested SQLAlchemy==1.1.11
chatterbot 0.8.4 depends on sqlalchemy<1.3 and >=1.2
To fix this you could try to:
1. loosen the range of package versions you've specified
2. remove package versions to allow pip attempt to solve the dependency conflict

One way that works for now is to use the legacy resolver. You can get the legacy resolver by (1) downgrading pip, or (2) using the --use-deprecated flag.
Using an older pip version
I know that pip==20.1.1 uses the old resolver, you could downgrade to that version.
pip install pip==20.1.1
Using the --use-deprecated flag
You can also use the legacy resolver with newer versions of pip with this flag (I tested this with pip==22.3.1).
pip install --use-deprecated=legacy-resolver .......
(took me forever to find this flag, btw)

requests 2.21.0 has requirement urllib3<1.25,>=1.21.1, but you'll have urllib3 1.25.2 which is incompatible.

Successfully installed certifi-2019.3.9 chardet-3.0.4 elasticsearch-7.0.0 idna-2.8 requests-2.21.0 urllib3-1.25.2
I want to understand this warning that appeared in the above output:
requests 2.21.0 has requirement urllib3<1.25,>=1.21.1, but you'll have urllib3 1.25.2 which is incompatible.
Why did pip install urllib3 1.25.2? It does not seem to make sense. The required dependencies are:
elasticsearch==7.0.0 requires urllib3>=1.21.1 (source)
requests==2.21.0 requires urllib3>=1.21.1,<1.25 (source)
Both dependencies could have been easily satisfied by installing urllib3 1.24.3. Why did pip3 then install urllib3 1.25.2? Isn't deciding the correct version according to the available requirements one of its responsibility?
It this a bug in pip3 or is this functioning as designed?
Update on 10th of November 2020
Install beta version of pip, it will solve the dependencies correctly for you.
Or install latest stable and run pip install --use-feature=2020-resolver.
Original answer
As it is now, pip doesn’t have true dependency resolution, but instead simply uses the first specification it finds for a project.
You can add constraints.txt file with urllib3==1.24.3 and then invoke:
$ pip install -r requirements.txt -c contraints.txt
That would do the job. When updating requirements remember to update also contraints.
Alternatively you can use one of Python dependency managers:
Pipenv
Poetry
pip-tools
DepHell
See Requirements Files and Constraints Files sections in pip user guide and Managing Application Dependencies tutorial.
I want to upgrade ply so I'm running -
pip install ply --upgrade
and I get the error (marked with **) -

**Cannot uninstall 'ply'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.**
You are using pip version 10.0.1, however version 18.0 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.
How do I solve this?
I am using Ubuntu 16.04 and I have Python 2.7 and Python 3.5 installed. I want to use h5py in both versions.
However, if I type
pip3 install h5py
it says
Requirement already satisfied: h5py in /home/veronika/.local/lib/python2.7/site-packages
Requirement already satisfied: six in /home/veronika/.local/lib/python2.7/site-packages (from h5py)
Requirement already satisfied: numpy>=1.7 in /home/veronika/.local/lib/python2.7/site-packages (from h5py)
and with Python 3 it cannot import h5py.
Any ideas for fixing this?
Try tell pip what Python version you want to install the package for:
Ex.:
python3 -m pip install h5py

You can install conda 4.2.7 using pip and then update it to the latest version.
auxlib is required in python 3.6.1. Install it using pip3 install auxlib
Now install conda 4.2.7 using pip3 install conda==4.2.7 and then update it using conda update conda.
