I am starting to use VS Code, but pylint is not installed and it gives me an error.
I try to install pylint using pip, but it gives me an error code.

This is a bug of pip for now, see https://github.com/pypa/pip/issues/9203. The pip does something wrong in its package-dependencies handling. And there is a workaround listed in this issue, use --use-deprecated=legacy-resolver. And be noted: This will work until we release pip 21.0.
So run pip install --use-deprecated=legacy-resolver pylint will resolve this problem. This works for me on win10, finally I got lazy-object-proxy 0.0.0 and pylint 2.6.0 installed, though 0.0.0 is kinda weird.
I had the same issues with Python 3.9 & Pylint.
Even when I tried the answers given here, nothing worked. I kept on getting Error messages.
All my issues where fixed by doing the following:
Uninstalled Python 3.9.1
Installed Python 3.7.9 - (Remember to click the box add to PATH)
Verifying Python Installation:
3.1 python --version, This should give you Python 3.7.9
If it doesn't and you get an Error, you need to configure your PATH, here is a video on how to fix that:
https://www.youtube.com/watch?v=vWxQG70GqT4&list=PL914uJ85wHwJ4WYvHEhPHSgG2oyi7Azat&index=11&ab_channel=KyleCook
Verifying pip Installation:
4.1 pip --version (I got another Error here again)
i.e.: ModuleNotFoundError: No module named 'pip' python3
I fixed that by:
4.1.1 python -m ensurepip
4.1.2 python -m pip install --upgrade pip
Ref: ModuleNotFoundError: No module named 'pip' python3
Install Pylint for Python 3.6+:
5.1 pip install pylint --upgrade
Ref: https://pypi.org/project/pylint/
This worked for me.

So I am trying to install pyaudio and it gives the _portaudio error, so people online told me to install it through pipwin, so I run this command:
pip install pipwin
Then when i type:
pipwin install pyaudio
This shows up:
'pipwin' is not recognized as an internal or external command,
operable program or batch file.
So i reboot, thinking that's the problem. Same message. Then I go ahead and uninstall pipwin and installs it again to find any potential errors that I missed. This shows up in red text:
ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
conda-repo-cli 1.0.4 requires pathlib, which is not installed.
anaconda-project 0.10.1 requires ruamel-yaml, which is not installed.
cookiecutter 1.7.2 requires Jinja2<3.0.0, but you have jinja2 3.0.3 which is incompatible.
cookiecutter 1.7.2 requires MarkupSafe<2.0.0, but you have markupsafe 2.0.1 which is incompatible.
Now I think oh, let's just install pathlib.
pip install pathlib
but then, ofcourse it's not that easy:

So i go ahead and try downloading setup tools, only for this to happen:

What is happening, why is it failing. Even more of a mindblow is that this is like 3 levels of just errors, trying to install PyAudio. Please help, this worked before I switched hard drives and had to reinstall Windows.
Sometimes when i install a module, i have to use py -m pip install {module} after cd C:\. Also make sure you have latest versions on pip.
I have some issues with fxcm packages and I need to install python-socketio 4.4.0. However, pip cannot this version.

The == operator is used to specify the version wanted, like the follow sintax:

I'm having trouble installing the proper version of PyBrain. This is a problem.

As you can see, it keeps installing PyBrain 0.3.1 even though I'm pulling in the 0.3.3 folder. Why is this happening and how can I fix this.
Download this package and see its setup.py, you will see version="0.3.1", so this is a bug made by author.
You have nothing to do with it except for modifying source code by yourself.
When installing the Fuel machine learning library, I got stuck with some dependencies issues:

.. ERROR:: Could not find a local HDF5 installation.
You may need to explicitly state where your local HDF5 headers and
library can be found by setting the ``HDF5_DIR`` environment
variable or by using the ``--hdf5`` command-line option.
----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-wMS1d3/tables
Then after I have done (Installing h5py on an Ubuntu server):
sudo apt-get install libhdf5-dev
sudo HDF5_DIR=/usr/lib/x86_64-linux-gnu/hdf5/serial/ pip install h5py
And then I had to also update my cython with:
sudo pip install cython
My question is not about how to fix the installation issues but what does this command mean?
sudo HDF5_DIR=/usr/lib/x86_64-linux-gnu/hdf5/serial/ pip install h5py
What does specifying the HDF5_DIR do?
Why didn't the fuel dependencies automatically install from the:
https://github.com/mila-udem/fuel/blob/master/requirements.txt
https://github.com/mila-udem/fuel/blob/master/setup.py
What should I do to update the setup.py from fuel so that it can automatically pip install the dependencies?
You do not need to make any modifications to the setup.py from fuel. Just make sure HDF5_DIR is set correctly before updating the lib.
Explanations:
If you look at your error log, you can see that it fails at installing the h5py python lib that is a dependency of fuel. It also tells you why it failed at the end, basically it is because h5py use the C library hdf5 and it needs the headers of this lib to use it.
So the sudo apt-get install libhdf5-dev that you executed is to install the development version of this C library (you can gess that by the -dev). The dev versions install the headers of the lib and not just the compiled lib.
Then, the HDF5_DIR env variable is nedded to tell h5py setup where to find those headers.
So if you whant to update the fuel lib next time, make sure that the HDF5_DIR is set correctly and then it will update its dependencies (including h5py).
I'm trying to use apns-client 0.2.1 but I only get an error message.
22:56:01 $ pip install apnsclient==0.2.1
Collecting apnsclient==0.2.1
Could not find a version that satisfies the requirement apnsclient==0.2.1 (from versions: 0.1)
No matching distribution found for apnsclient==0.2.1
How can I install 0.2.1 version and then save it in requirements.txt? I need it in this way because my hosting use this file too.
The package is called apns-client, notice the dash.
pip install apns-client
