Recently, I have attempted to complete a neural network and technical analysis program for the prediction of fluctuations within the financial equities markets available via utilised databases; I am currently utilising the module Quandl for the purposes of financial information retrieval, while the program itself remains within the Google Colaboratory integrated development environment. For the purposes of this project, I have recently attempted to install a Python wrapper for the module TA-Lib, which contains a portion designed for the analysis of candlestick chart patterns; the documentation for the library and page are shown below:
https://github.com/mrjbq7/ta-lib
https://mrjbq7.github.io/ta-lib/func_groups/pattern_recognition.html
Within the Colaboratory editor, I attempted to install the program via the command:
pip install TA-Lib
as specified; however, the integrated development environment provided the following error message:

Is there an alternative method responsible for the avoidance of this inevitable error? If not, is there a method to download this module within Colaboratory which would bypass such processes? Thank you for your assistance.
Try this
!wget http://prdownloads.sourceforge.net/ta-lib/ta-lib-0.4.0-src.tar.gz
!tar -xzvf ta-lib-0.4.0-src.tar.gz

I assume you were trying to install web3 using the pip command python -m pip install web3 (or pip install web3 for short, although the first form is better). I got roughly the same error when performing this command.
The problem isn't in web3, however, but in one of its dependencies. You can check this by installing it with --no-deps, which works fine:
C:\temp\stack_overflow>pip install --no-deps web3
Collecting web3
Using cached web3-5.24.0-py3-none-any.whl (487 kB)
Installing collected packages: web3
Successfully installed web3-5.24.0
But this probably doesn't solve your problem, because the module likely doesn't work without all its dependencies. The dependency that is failing in this case is bitarray. This is because bitarray is a source package. The documentation of this library contains installation instructions:
If you have a working C compiler, you can simply:
$ pip install bitarray
If you rather want to use precompiled binaries, you can:
conda install bitarray (both the default Anaconda repository as well as conda-forge support bitarray)
download Windows wheels from Chris Gohlke
I did the last step: downloading the wheel from the mentioned website, and installing it with pip install bitarray-2.3.4-cp38-cp38-win_amd64.whl (your version may be different of course). This worked like a charm.
However, web3 also has a dependency on lru-dict, which resulted in the same issue. Unfortunately, I could not find pre-compiled binaries for this package, so if you encounter the same problem, you now have two options:
Use conda-forge to install your packages. I personally don't have experience with conda, but conda-forge seems to support the lru-dict package (as well as the above-mentioned bitarray package).
Make sure to install Microsoft Visual C++ 14.0 or greater. As mentioned in the error message: Get it with "Microsoft C++ Build Tools": https://visualstudio.microsoft.com/visual-cpp-build-tools/
This page contains some more detailed instructions on how to download and install it.
I got it working by updating the Visual C++ compiler to the latest version and make sure to include the Windows 10 SDK, as explained in this SO answer.

NB: It is recommended to install web3 in a clean virtual environment, to avoid version conflicts with other installed modules.
Let me tell you one perfect solution for such problems. It is always better to have a virtual environment which solves the version problems of the different problems ... you may follow the below process and it will help
# Install pip if it is not available:
$ which pip || curl https://bootstrap.pypa.io/get-pip.py | python
# Install virtualenv if it is not available:
$ which virtualenv || pip install --upgrade virtualenv
# *If* the above command displays an error, you can try installing as root:
$ sudo pip install virtualenv
# Create a virtual environment:
$ virtualenv -p python3 ~/.venv-py3
# Activate your new virtual environment:
$ source ~/.venv-py3/bin/activate
# With virtualenv active, make sure you have the latest packaging tools
$ pip install --upgrade pip setuptools
# Now we can install web3.py...
$ pip install --upgrade web3
I have an equal problem and I resolved with anaconda.
First check your Microsoft Visual C++, install and restart your computer.
Second, you should watch a some Anaconda's tutorial, after that, you need to create a virtual environment, pick the folder and done.
Example in code : In to cmd
1) conda create --name 'pick a name'
2) conda activate 'yourname'
3) conda install -c conda-forge web3
After that, go to your text editor and pick how python interpreter (alt+shift+p in VSC), the one you already created like ENVS, look in C:\Users'youruser'.conda\envs'yournameENVS.

I tried installing from the github repository and i get the same output when i write !pip install -r requirements.txt, i was using the offical documentation.
Seeing to the logs error is regarding the webkit-server library and seeing in the GitHub issues of webkit-server the library came to the pull request, which helped me install webkit-server and then install dryscrape follow the below commands to install it in your Colab.
Command 1:
!pip install git+https://github.com/niklasb/webkit-server.git#refs/pull/35/head
Command 2:
!pip install dryscrape
This will successfully install dryscrape.

Do look at the WARNING. It says that I ought to have version 19.3.1 but upon running upgrade the very same cmd shows that I am already using the latest version 19.3.1. How is this possible?
I am facing a lot of confusions. Can anyone ALSO recommend some websites for beginners for installing GoogleAssistant on PC. I have tried Github but haven't been able to comprehend it.

EDIT: Looks like I have to install Visual Studio 2015...Can I install dlib without VS 2015? I already have older versions pre-installed with Windows.
I am using Python 3.5, trying to install dlib on PyCharm in the terminal and this is what I am getting, and every search on these errors I do... I find stuff on Visual Studio which I don't have the GUI + I don't have vcvarsall.bat in the VC folder of any of the Visual Studio versions (8, 11, 12, 14). I have searched a good amount before posting this question on the Web.
Do I need to download Visual Studio latest version to get vcvarsall.bat ?
