Could not find function xmlCheckVersion in library libxml2 during Scrapy install - cmd

I've been looking through endless forums trying to solve this and I still haven't found an answer that works. I'm new to windows and I'm trying to set things up as I have them on my Mac but the Command Line is presented challenges (what's the equivalent to sudo?) eg, on mac I would type 'sudo pip install scrapy', what's the equivalent on windows? I'm getting this error below and I cannot seem to find my way around it. Any thoughts greatly appreciated.

This seems to be related to lxml installation which is a scrapy dependency.
The official documentation page has some solutions but it recommends to use unofficial binaries for windows operating system which can be found here:

can't install pycocotools "Cannot open include file: 'math.h': No such file or directory" [duplicate]

I'm trying to use object detection models from Tensorflow and need to get pycocotools installed. I'm doing this from a python (3) virtual environment on a Windows 10 machine. There seems to be some known issues around getting this working on Windows, and I'm pretty sure I've tried them all.
I've tried pip-installing pycocotools, with this error (fails building wheel):

I've tried installing Visual C++ Build Tools (2015 version recommended by many other answers), but got the error that it was unable to find/download setup package, so I've made sure I have updates to the 2019 build tools, and they are added to my path.
Error I was getting is like this one. I also followed the video at the bottom of that solution and it didn't help.
I've tried using the suggested windows install for pycocotools (pycocotools-windows), which gives the following error:
(env) PS C:\Users\la01043601\ML_CameraVision\humanDetection> pip install cocoapi-windows
ERROR: Could not find a version that satisfies the requirement cocoapi-windows (from versions: none)
ERROR: No matching distribution found for cocoapi-windows
(env) PS C:\Users\la01043601\ML_CameraVision\humanDetection> pip install pycocotools-windows
ERROR: Could not find a version that satisfies the requirement pycocotools-windows (from versions: none)
ERROR: No matching distribution found for pycocotools-windows
Python and pip are on my Windows path. I gave up on one tutorial due to this, just to find the next one has a pycocotools dependency too.

Edit edit I forgot to mention that in the past couple days I also tried troubleshooting the math.h error, which suggests switching an include statement from "math.h" to "cmath", and using "quotes" instead of angle brackets, and since this happens when installing from a downloaded repo I even forked the repo the made the change on my version to download from there. Error as follows (now related to a missing 'crtdbg.h' file and I don't understand how everything works under the hood in Build Tools):

Failed to build pycocotools
ERROR: Could not build wheels for pycocotools which use PEP 517 and cannot be installed directly
I solved the problem by conda install pycocotools -c conda-forge
ps: python version==3.7.12
after everything failed, I installed visual c++ build tools using the link below
Visit https://myvs.download.prss.microsoft.com/db/mu_visual_cpp_build_tools_2015_update_3_x64_dvd_dfd9a39c.iso?t=36429cde-dc63-4657-8114-1c74ae0da9bf&e=1645739068&h=e153f9afa2fa5fd4ffae5a1cc714a2ab704115af952dfb82e1761e5553c7999a&su=1
after it has downloaded open it and run the setup file, everything should run smoothly.
Then in your environment run this code:-
pip install cython
then this one:
pip install git+https://github.com/philferriere/cocoapi.git#subdirectory=PythonAPI
that should work, I am using TensorFlow version 2.3, Python 3.8
You may need to install:
sudo apt install python3.9-dev
Place another python version if you need 3.8 etc.
Then pycocotools is installed correctly, helped in my case when "Python.h" was not found.
Don't Forget to Restart your pc after install visual c++ build tools, in my case everything not working until I restart my PC after installing the build tools.

consider using pytesseract, worked for me on python 3.6: pip install pytesseract
If you encounter problems installing it directly by running the above command, try this link :
http://www.lfd.uci.edu/~gohlke/pythonlibs/
Use the "find" tool to find pytesseract and in the directory where its downloaded, hold shift and right click, youll get an option to open a command window there and run:
pip install "filename"
You could also try downloading tesseract-ocr from the link above and perform the installation offline like i just explained.
Never quite figured out why, but some installations that failed worked when dowloaded. Hope that helps.
The fix for this issue is on the Compiling Page of tesseract-ocr
sudo apt-get install libleptonica-dev
I can tell you that this fixed the issue on a Raspberry Pi (Jessie and Stretch) and Debian (8 and 9)

Would someone help? I am new to Python.
That's because you have an Incompatible MySQL-C/Python connector for Python. Latest Connector comes only for Python3.
Just follow these steps:
Download, MySQL-C/Python27 Connector
Install it.
Open CMD as admin.
Type the following in CMD.
mklink /d "C:\Program Files (x86)\MySQL\MySQL Connector C 6.0.2" "C:\Program Files\MySQL\MySQL Connector C 6.0.2"
Try installing now, python -m pip install MySQL-Python
TaDa! It works!
This answer is from All of common comments in asked question of this type!
Download the 32-bit version from MySQL-C Download Page
Try installing now, python -m pip install MySQL-Python
Worked perfectly for me. You have to install the 32-bit version even inside a 64-bit Windows environment.

Can anyone tell me whats the problem?
Download the pre-compiled whl file for mysql-python from from Christophe Gohlke’s Library of pre-compiled python packages for windows from the below location.
https://www.lfd.uci.edu/~gohlke/pythonlibs/#mysql-python
Now got to directory where you downloaded that file and open command prompt there.
Now run below command pip install xxx.whl
Best Luck !!
You can try...
pip install mysqlclient==1.3.4
It worked for me.
If the above command doesn't work try this...
pip install --only-binary :all: mysqlclient
both worked for me.
I got a same error.
I solved it by install mysql-connector
You can get a pre-compiled version from Christophe Gohlke’s Library of pre-compiled python packages for windows. Specifically, you can find the MySQL_python package here
Other alternatives would be to use a python distribution that comes with many packages pre-compiled and available for easy installation. Two examples are:
Anaconda Python Distribution
Enthought Canopy Python Distribution
You are missing Visual Studio C++ from your system or the correct environment for VS is not set properly based on the error in your question: "error: command 'C:\Program Files (x86)\Common Files\Microsoft\Visual C++ for Python\9.0\VC\Bin\cl.exe' failed with exit status 2"
Please check if you have C++ compiler installed at "C:\Program Files (x86)\Common Files\Microsoft\Visual C++ for Python\9.0\VC\Bin\cl.exe". If you do not have this installed it is available from Microsoft here: python27 Compiler
If you have VS installed try running the pip install from visual studio command prompt ,which generally would have all the environment created or try to run vcvarsall.bat from "C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\bin\" folder
Simply go to the site:
http://www.lfd.uci.edu/~gohlke/pythonlibs/#mysql-python
and download mysqlclient wheel file according to your python version and operating system bit specification, then install the downloaded file with typing
pip install downloaded_whl_file_name
Finally install mysqldb with command:
pip install flask-mysqldb
In my case I had to install mysql-connector with the same bitness as my python.
So although I run 64bit windows 10, I have 32bit python 2.7 installed so I had to install 32bit mysql-connector from here
to overcome the error.
The following action, mentioned above by zio, has solved my problem:
You can get a pre-compiled version from Christophe Gohlke’s Library of pre-compiled python packages for windows. Specifically, you can find the MySQL_python package here.
After get the file, install it using pip install.

pip install distarray --> mpi.h not found, cannot install mpi4py

I have tried to install distarray which requires a C++ compiler (which I got from MS) and mpi4py. The installer cannot locate mpi.h and I cannot even install mpi4py by itself. The documentation says I should set an ENV-path, but which path, to Visual studio?

failure.
removing: _configtest.c _configtest.obj

error: Cannot find 'mpi.h' header. Check your configuration!!!
What am I doing wrong? I have tried both in a Windows and a Linux environment without luck. As admin and sudo.
(Should there be tags for mpi4py, mpi.h, mpi.cfg as I cannot create these as a new user)
